Lager ( / ˈ l ɑː ɡ ər / ) is a style of beer brewed and conditioned at low temperature. Lagers can be pale , amber , or dark . Pale lager is the most widely consumed and commercially available style of beer. The term " lager " comes from the German word for "storage", as the beer was stored before drinking, traditionally in the same cool caves in which it was fermented.
106-723: Steinlager (sometimes known as Steinlager Classic ) is a lager -style beer brewed by Lion in East Tāmaki , a suburb of Auckland , New Zealand. It has won several prizes, notably at beer competitions in the United States , and is New Zealand's biggest export beer. In 1957 the New Zealand Minister of Finance , Arnold Nordmeyer , threatened to cut international beer imports as part of his "black budget" and challenged New Zealand's brewers to "come up with an international-style lager beer". Lion (then New Zealand Breweries) produced
212-467: A copper to reddish-brown colour , low bitterness, low hop profile, a malty aroma, and 4.8–5.4% alcohol by volume . Pale lagers were not common until the later part of the 19th century when the use of lighter roasted malts spread. Dark lagers may be called Dunkel , tmavé or Schwarzbier depending on region, colour or brewing method. Tmavé is Czech for "dark" – beers which are so dark as to be black are termed černé pivo , "black beer". Dunkel
318-435: A "cooling culture" as majority of people used ice and iceboxes to store their dairy products, fish, meat, and even fruits and vegetables. These early cold storage practices paved the way for many Americans to accept the refrigeration technology that would soon take over the country. The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755. Cullen used
424-463: A 1.7% increase in dairy consumption and overall protein intake by 1.25% annually in the US after the 1890s. People were not only consuming these perishables because it became easier for they themselves to store them, but because the innovations in refrigerated transportation and storage led to less spoilage and waste, thereby driving the prices of these products down. Refrigeration accounts for at least 5.1% of
530-509: A beer the following year named Steinecker, named after the company whose equipment the beer was made in. The beer's name was changed in 1962, not in response to a challenge from the Steinecker company, but to distinguish it from Heineken . In 1973 Steinlager was launched in the United States and an American consultant suggested that to become successful the company should change the colour of their bottles to match that of other premium beers. As
636-454: A company acquired by the W.C. Bradley Co., which went on to produce the first commercial ice-makers in the US. By the 1870s, breweries had become the largest users of harvested ice. Though the ice-harvesting industry had grown immensely by the turn of the 20th century, pollution and sewage had begun to creep into natural ice, making it a problem in the metropolitan suburbs. Eventually, breweries began to complain of tainted ice. Public concern for
742-470: A concentration of business, shopping, and entertainment outside a traditional downtown or central business district in what had previously been a residential or rural area. There were several factors contributing to the growth of these cities such as Los Angeles, Las Vegas, Houston, and Phoenix. The factors that contributed to these large cities include reliable automobiles, highway systems, refrigeration, and agricultural production increases. Large cities such as
848-553: A deep tan or amber color. Among the common styles of amber lager are Märzen , traditionally brewed in Munich for the celebration of Oktoberfest , Bock , a higher alcohol-content amber lager originating in Einbeck in central Germany, and the widely distributed Vienna lager. The Vienna lager style was developed by Anton Dreher in the late 1830s. While on a trip to England and Scotland in 1833 with Gabriel Sedlmayr, Dreher gained knowledge of
954-589: A demand for New Zealand meat around the world. In order to meet this new demand, the farmers improved their feed so sheep could be ready for the slaughter in only seven months. This new method of shipping led to an economic boom in New Zealand by the mid 1890s. In the United States, the Meat Inspection Act of 1891 was put in place in the United States because local butchers felt the refrigerated railcar system
1060-462: A few years, 300,000 people in rural areas of the United States had received power in their homes. While electricity dramatically improved working conditions on farms, it also had a large impact on the safety of food production. Refrigeration systems were introduced to the farming and food distribution processes, which helped in food preservation and kept food supplies safe . Refrigeration also allowed for shipment of perishable commodities throughout
1166-483: A greater variety of crops, fertilizers, pesticides, and improved technology. Improved technology has decreased the risk and time involved for agricultural management and allows larger farms to increase their output per person to meet society's demand. Prior to 1882, the South Island of New Zealand had been experimenting with sowing grass and crossbreeding sheep, which immediately gave their farmers economic potential in

#17328581541091272-581: A higher strength. The Vienna lager style has survived to this day, mostly thanks to the emerging microbrewing, home-brewing and craft beer scene in the United States of the 1980s and 1990s. Due to the influence of the American craft beer movement, Vienna lager can again be found in Europe, including traditional Austrian breweries like Ottakringer and Schwechater who have made this pale amber beer style part of their range of beers again. A Vienna lager typically has
1378-496: A horse-drawn ice cutter in 1825. This invention as well as Tudor's success inspired others to get involved in the ice trade and the ice industry grew. Ice became a mass-market commodity by the early 1830s with the price of ice dropping from six cents per pound to a half of a cent per pound. In New York City, ice consumption increased from 12,000 tons in 1843 to 100,000 tons in 1856. Boston's consumption leapt from 6,000 tons to 85,000 tons during that same period. Ice harvesting created
1484-455: A hybridization in the early fifteenth century. In 2011, a team of researchers claimed to have discovered that Saccharomyces eubayanus is responsible for creating the hybrid yeast used to make lager. Based on the numbers of breweries, lager brewing became the main form of brewing in the Kingdom of Bohemia between 1860 and 1870, as shown in the following table: In the 19th century, before
1590-518: A lack of ice-storehouses and iceboxes. As these two things became more widely available, individuals used axes and saws to harvest ice for their storehouses. This method proved to be difficult, dangerous, and certainly did not resemble anything that could be duplicated on a commercial scale. Despite the difficulties of harvesting ice, Frederic Tudor thought that he could capitalize on this new commodity by harvesting ice in New England and shipping it to
1696-402: A large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to human prehistory , but for thousands of years humans were limited regarding the means of doing so. They used curing via salting and drying , and they made use of natural coolness in caves , root cellars , and winter weather, but other means of cooling were unavailable. In
1802-475: A larger concentration of agricultural sales coming from a smaller percentage of farms. Farms today have a much larger output per person in comparison to the late 1800s. This has resulted in new food sources available to entire populations, which has had a large impact on the nutrition of society. The seasonal harvesting of snow and ice is an ancient practice estimated to have begun earlier than 1000 BC. A Chinese collection of lyrics from this time period known as
1908-450: A man to death on a warm summer's day". In 1805, American inventor Oliver Evans described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum. In 1820, the English scientist Michael Faraday liquefied ammonia and other gases by using high pressures and low temperatures, and in 1834, an American expatriate to Great Britain, Jacob Perkins , built
2014-525: A more heavily hopped pale lager, is most often known as "Pilsner", "Pilsener", or "Pils". Other lagers are Bock , Märzen , and Schwarzbier . In the United Kingdom , the term commonly refers to pale lagers derived from the Pilsner style. While cold storage of beer, "lagering", in caves for example, was a common practice throughout the medieval period, bottom-fermenting yeast seems to have emerged from
2120-638: A pale amber colour. The beer style became well-known internationally, in particular due to the Dreher brewery's restaurant and beer hall at the International Exposition of 1867 in Paris, and started getting copied by many of the US-American lager breweries founded by German immigrants. The first amber-coloured Oktoberfest-Märzen brewed by Franziskaner-Leistbräu in 1872 was also a Vienna-style beer brewed to
2226-570: A pit called a Yakhchal and may have been the first group of people to use cold storage to preserve food. In the Australian outback before a reliable electricity supply was available many farmers used a Coolgardie safe , consisting of a room with hessian (burlap) curtains hanging from the ceiling soaked in water. The water would evaporate and thereby cool the room, allowing many perishables such as fruit, butter, and cured meats to be kept. Before 1830, few Americans used ice to refrigerate foods due to
SECTION 20
#17328581541092332-517: A process of cool fermentation , followed by maturation in cold storage. The German word "Lager" means storeroom or warehouse. The yeast generally used with lager brewing is Saccharomyces pastorianus . It is a close relative of the Saccharomyces cerevisiae yeast used for warm fermented ales. While prohibited by the German Reinheitsgebot tradition, lagers in some countries may include
2438-453: A proportion of adjuncts , usually rice or maize. Adjuncts entered United States brewing as a means of thinning out the body of beers, balancing the large quantities of protein introduced by six-row barley . Adjuncts are often used now in beermaking to introduce a large quantity of sugar, and thereby increase ABV , at a lower price than a formulation using an all-malt grain bill. There are, however, cases in which adjunct usage actually increases
2544-524: A pump to create a partial vacuum over a container of diethyl ether , which then boiled , absorbing heat from the surrounding air. The experiment even created a small amount of ice, but had no practical application at that time. In 1758, Benjamin Franklin and John Hadley , professor of chemistry, collaborated on a project investigating the principle of evaporation as a means to rapidly cool an object at Cambridge University , England . They confirmed that
2650-617: A refrigerant worldwide was curtailed in the Montreal Protocol of 1987. In the last century, refrigeration allowed new settlement patterns to emerge. This new technology has allowed for new areas to be settled that are not on a natural channel of transport such as a river, valley trail or harbor that may have otherwise not been settled. Refrigeration has given opportunities to early settlers to expand westward and into rural areas that were unpopulated. These new settlers with rich and untapped soil saw opportunity to profit by sending raw goods to
2756-656: A result, the original brown bottle colour was changed to green. According to Steinlager, the Steinlager Pure beer contains malted barley , hops , yeast and water. The entire Steinlager range of beer is not gluten-free, and isn't considered suitable for those with coeliac disease . In 1991, another beer bearing the Steinlager name was introduced. Steinlager Blue was marketed using an advertising campaign featuring The Blues Brothers . The two different tasting beers were known as Steinlager Blue or Steinlager Green which related to
2862-430: A space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). Refrigeration is an artificial, or human-made, cooling method. Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. This work of energy transfer
2968-636: A triumph over physical difficulties, as would have been incredible, even unimaginable, a very few days ago...". The Marlborough —sister ship to the Dunedin – was immediately converted and joined the trade the following year, along with the rival New Zealand Shipping Company vessel Mataurua , while the German Steamer Marsala began carrying frozen New Zealand lamb in December 1882. Within five years, 172 shipments of frozen meat were sent from New Zealand to
3074-415: Is 3 to 5 °C (37 to 41 °F). In commerce and manufacturing, there are many uses for refrigeration. Refrigeration is used to liquefy gases – oxygen , nitrogen , propane , and methane , for example. In compressed air purification, it is used to condense water vapor from compressed air to reduce its moisture content. In oil refineries , chemical plants , and petrochemical plants, refrigeration
3180-513: Is German for "dark". At 4.5% to 6% abv , Dunkel is weaker than Doppelbock , a stronger dark Bavarian beer. Dunkel was the original style of the Bavarian villages and countryside. Schwarzbier , a much darker, almost black beer with a chocolate or licorice-like flavour, similar to stout , is brewed in Saxony and Thuringia . Refrigeration Refrigeration is any of various types of cooling of

3392-408: Is simply Steinlager Classic served at 0 degrees Celsius . Steinlager Edge was a mid-strength, low-carb variant of Steinlager. It is made from the same hops as Classic and Pure but has an alcohol content of just 3.5% compared to 5.0%. It was discontinued in 2013 due to poor sales. In 2016, Steinlager Tokyo Dry was introduced as "New Zealand raw ingredients meet Japanese brewing mastery". Steinlager
3498-471: Is supplied from a high-temperature source to the engine, part of the heat being used to produce work and the rest being rejected to a low-temperature sink. This satisfies the second law of thermodynamics . A refrigeration cycle describes the changes that take place in the refrigerant as it alternately absorbs and rejects heat as it circulates through a refrigerator . It is also applied to heating, ventilation, and air conditioning HVACR work, when describing
3604-508: Is traditionally driven by mechanical means (whether ice or electromechanical machines), but it can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration has many applications, including household refrigerators , industrial freezers , cryogenics , and air conditioning . Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Refrigeration has had
3710-403: Is used to cool the ice down further (as in a traditional ice-cream maker ). Dry ice can reliably bring the temperature well below water freezing point. This consists of a refrigeration cycle, where heat is removed from a low-temperature space or source and rejected to a high-temperature sink with the help of external work, and its inverse, the thermodynamic power cycle . In the power cycle, heat
3816-454: Is used to maintain certain processes at their needed low temperatures (for example, in alkylation of butenes and butane to produce a high- octane gasoline component). Metal workers use refrigeration to temper steel and cutlery. When transporting temperature-sensitive foodstuffs and other materials by trucks, trains, airplanes and seagoing vessels, refrigeration is a necessity. Dairy products are constantly in need of refrigeration, and it
3922-544: Is usually mild, and the producers often recommend that the beers be served refrigerated. Pale lager is a very pale to golden -coloured lager with a well attenuated body and noble hop bitterness. The brewing process for this beer developed in the mid 19th century when Gabriel Sedlmayr took pale ale brewing techniques back to the Spaten Brewery in Germany and applied it to existing lagering brewing methods. This approach
4028-537: The Sleaping , describes religious ceremonies for filling and emptying ice cellars. However, little is known about the construction of these ice cellars or the purpose of the ice. The next ancient society to record the harvesting of ice may have been the Jews in the book of Proverbs, which reads, "As the cold of snow in the time of harvest, so is a faithful messenger to them who sent him." Historians have interpreted this to mean that
4134-618: The British Isles . Although not actually the first to achieve successful transportation of frozen goods overseas (the Strathleven had arrived at the London docks on 2 February 1880 with a cargo of frozen beef, mutton and butter from Sydney and Melbourne ), the breakthrough is often attributed to William Soltau Davidson , an entrepreneur who had emigrated to New Zealand . Davidson thought that Britain's rising population and meat demand could mitigate
4240-631: The sushi / sashimi industry in Japan. Before the discovery of refrigeration, many sushi connoisseurs were at risk of contracting diseases. The dangers of unrefrigerated sashimi were not brought to light for decades due to the lack of research and healthcare distribution across rural Japan. Around mid-century, the Zojirushi corporation, based in Kyoto, made breakthroughs in refrigerator designs, making refrigerators cheaper and more accessible for restaurant proprietors and

4452-440: The "process" of refrigerant flow through an HVACR unit, whether it is a packaged or split system. Heat naturally flows from hot to cold. Work is applied to cool a living space or storage volume by pumping heat from a lower temperature heat source into a higher temperature heat sink. Insulation is used to reduce the work and energy needed to achieve and maintain a lower temperature in the cooled space. The operating principle of
4558-511: The 19th century, they began to make use of the ice trade to develop cold chains . In the late 19th through mid-20th centuries, mechanical refrigeration was developed, improved, and greatly expanded in its reach. Refrigeration has thus rapidly evolved in the past century, from ice harvesting to temperature-controlled rail cars , refrigerator trucks , and ubiquitous refrigerators and freezers in both stores and homes in many countries. The introduction of refrigerated rail cars contributed to
4664-732: The Caribbean islands as well as the southern states. In the beginning, Tudor lost thousands of dollars, but eventually turned a profit as he constructed icehouses in Charleston, Virginia and in the Cuban port town of Havana. These icehouses as well as better insulated ships helped reduce ice wastage from 66% to 8%. This efficiency gain influenced Tudor to expand his ice market to other towns with icehouses such as New Orleans and Savannah. This ice market further expanded as harvesting ice became faster and cheaper after one of Tudor's suppliers, Nathaniel Wyeth, invented
4770-626: The Jews used ice to cool beverages rather than to preserve food. Other ancient cultures such as the Greeks and the Romans dug large snow pits insulated with grass, chaff, or branches of trees as cold storage. Like the Jews, the Greeks and Romans did not use ice and snow to preserve food, but primarily as a means to cool beverages. Egyptians cooled water by evaporation in shallow earthen jars on the roofs of their houses at night. The ancient people of India used this same concept to produce ice. The Persians stored ice in
4876-655: The United Kingdom, of which only 9 had significant amounts of meat condemned. Refrigerated shipping also led to a broader meat and dairy boom in Australasia and South America. J & E Hall of Dartford , England outfitted the SS Selembria with a vapor compression system to bring 30,000 carcasses of mutton from the Falkland Islands in 1886. In the years ahead, the industry rapidly expanded to Australia, Argentina and
4982-407: The United States and a population of 127 million. Yet, while the United States population has continued to climb, citizens pursuing agriculture continue to decline. Based on the 2007 US Census, less than one percent of a population of 310 million people claim farming as an occupation today. However, the increasing population has led to an increasing demand for agricultural products, which is met through
5088-474: The United States. By the 1890s, refrigeration played a vital role in the distribution of food. The meat-packing industry relied heavily on natural ice in the 1880s and continued to rely on manufactured ice as those technologies became available. By 1900, the meat-packing houses of Chicago had adopted ammonia-cycle commercial refrigeration. By 1914, almost every location used artificial refrigeration. The major meat packers , Armour, Swift, and Wilson, had purchased
5194-470: The United States. As a result, United States farmers quickly became the most productive in the world, and entire new food systems arose. In order to reduce humidity levels and spoiling due to bacterial growth, refrigeration is used for meat, produce, and dairy processing in farming today. Refrigeration systems are used the heaviest in the warmer months for farming produce, which must be cooled as soon as possible in order to meet quality standards and increase
5300-525: The acceptance of the refrigerated rail cars led to an increase of car loads from 4,500 carloads in 1895 to between 8,000 and 10,000 carloads in 1905. The Gulf States, Arkansas, Missouri and Tennessee entered into strawberry production on a large-scale while Mississippi became the center of the tomato industry . New Mexico, Colorado, Arizona, and Nevada grew cantaloupes. Without refrigeration, this would have not been possible. By 1917, well-established fruit and vegetable areas that were close to eastern markets felt
5406-458: The adoption of the refrigerated rail car. After the slow adoption of the refrigerated car, the beef packing industry dominated the refrigerated rail car business with their ability to control ice plants and the setting of icing fees. The United States Department of Agriculture estimated that, in 1916, over sixty-nine percent of the cattle killed in the country was done in plants involved in interstate trade. The same companies that were also involved in

#17328581541095512-419: The advent of refrigeration, German brewers would dig cellars for lagering and fill them with ice from nearby lakes and rivers, which would cool the beer during the summer months. To further protect the cellars from the summer heat, they would plant chestnut trees , which have spreading, dense canopies but shallow roots which would not intrude on the caverns. The practice of serving beer at these sites evolved into
5618-489: The advent of the household refrigerator, people would have to shop on a daily basis for the supplies needed for their meals. The introduction of refrigeration allowed for the hygienic handling and storage of perishables, and as such, promoted output growth, consumption, and the availability of nutrition. The change in our method of food preservation moved us away from salts to a more manageable sodium level. The ability to move and store perishables such as meat and dairy led to
5724-500: The business was a costly failure. In 1842, John Gorrie created a system capable of refrigerating water to produce ice. Although it was a commercial failure, it inspired scientists and inventors around the world. France's Ferdinand Carre was one of the inspired and he created an ice producing system that was simpler and smaller than that of Gorrie. During the Civil War, cities such as New Orleans could no longer get ice from New England via
5830-526: The coastal ice trade. Carre's refrigeration system became the solution to New Orleans' ice problems and, by 1865, the city had three of Carre's machines. In 1867, in San Antonio, Texas, a French immigrant named Andrew Muhl built an ice-making machine to help service the expanding beef industry before moving it to Waco in 1871. In 1873, the patent for this machine was contracted by the Columbus Iron Works,
5936-414: The colour of the bottle or can it came in (although Steinlager Blue was sold in a brown bottle). Steinlager Blue was discontinued in the later 1990s, leaving just Steinlager Green which then dropped the green from the name. Note the only reason Steinlager Blue & Green tasted different was the bottle colour. Beers bottled in green or clear bottles degrade under UV light. Both Steinlager beers were brewed in
6042-537: The cost of manufacture. It is possible to use lager yeast in a warm fermentation process, such as with American steam beer ; while German Altbier and Kölsch are brewed with Saccharomyces cerevisiae top-fermenting yeast at a warm temperature, but with a cold-storage finishing stage, and classified as obergäriges lagerbier (top-fermented lager beer). Lagers range in colour from extremely pale, through amber beers such as Vienna lager, to dark brown and black Dunkel and Schwarzbier. The depth of colour comes from
6148-479: The debate of how to compete against the American advantage of unrefrigerated beef sales to the United Kingdom . In 1873 he prepared the sailing ship Norfolk for an experimental beef shipment to the United Kingdom, which used a cold room system instead of a refrigeration system. The venture was a failure as the ice was consumed faster than expected. The first gas absorption refrigeration system using gaseous ammonia dissolved in water (referred to as "aqua ammonia")
6254-485: The development of smaller, lighter, and cheaper refrigerators. The average price of a refrigerator dropped from $ 275 to $ 154 with the synthesis of Freon. This lower price allowed ownership of refrigerators in American households to exceed 50% by 1940. Freon is a trademark of the DuPont Corporation and refers to these CFCs, and later hydro chlorofluorocarbon (HCFC) and hydro fluorocarbon (HFC), refrigerants developed in
6360-438: The east. The refrigerated car made it possible to transport perishable crops hundreds and even thousands of kilometres or miles. The most noticeable effect the car gave was a regional specialization of vegetables and fruits. The refrigeration rail car was widely used for the transportation of perishable goods up until the 1950s. By the 1960s, the nation's interstate highway system was adequately complete allowing for trucks to carry
6466-405: The eastern cities and states. In the 20th century, refrigeration has made "Galactic Cities" such as Dallas, Phoenix and Los Angeles possible. The refrigerated rail car ( refrigerated van or refrigerator car ), along with the dense railroad network, became an exceedingly important link between the marketplace and the farm allowing for a national opportunity rather than a just a regional one.

6678-456: The existing farms in the United States today. This is a partial result of the market created for the frozen meat trade by the first successful shipment of frozen sheep carcasses coming from New Zealand in the 1880s. As the market continued to grow, regulations on food processing and quality began to be enforced. Eventually, electricity was introduced into rural homes in the United States, which allowed refrigeration technology to continue to expand on
6784-460: The exportation of meat. In 1882, the first successful shipment of sheep carcasses was sent from Port Chalmers in Dunedin , New Zealand, to London . By the 1890s, the frozen meat trade became increasingly more profitable in New Zealand, especially in Canterbury , where 50% of exported sheep carcasses came from in 1900. It was not long before Canterbury meat was known for the highest quality, creating
6890-507: The farm, increasing output per person. Today, refrigeration's use on the farm reduces humidity levels, avoids spoiling due to bacterial growth, and assists in preservation. The introduction of refrigeration and evolution of additional technologies drastically changed agriculture in the United States. During the beginning of the 20th century, farming was a common occupation and lifestyle for United States citizens, as most farmers actually lived on their farm. In 1935, there were 6.8 million farms in
6996-454: The feasibility and then popularity of the modern supermarket. Fruits and vegetables out of season, or grown in distant locations, are now available at relatively low prices. Refrigerators have led to a huge increase in meat and dairy products as a portion of overall supermarket sales. As well as changing the goods purchased at the market, the ability to store these foods for extended periods of time has led to an increase in leisure time. Prior to
7102-523: The first working vapor-compression refrigeration system in the world. It was a closed-cycle that could operate continuously, as he described in his patent: His prototype system worked although it did not succeed commercially. In 1842, a similar attempt was made by American physician, John Gorrie , who built a working prototype, but it was a commercial failure. Like many of the medical experts during this time, Gorrie thought too much exposure to tropical heat led to mental and physical degeneration, as well as
7208-430: The general public. Methods of refrigeration can be classified as non-cyclic , cyclic , thermoelectric and magnetic . This refrigeration method cools a contained area by melting ice, or by sublimating dry ice . Perhaps the simplest example of this is a portable cooler, where items are put in it, then ice is poured over the top. Regular ice can maintain temperatures near, but not below the freezing point, unless salt

The railroad companies were slow to adopt this new invention because of their heavy investments in cattle cars, stockyards, and feedlots. Refrigeration cars were also complex and costly compared to other rail cars, which also slowed
7526-529: The late 1920s. Thaddeus Lowe , an American balloonist, held several patents on ice-making machines. His "Compression Ice Machine" would revolutionize the cold-storage industry. In 1869, he and other investors purchased an old steamship onto which they loaded one of Lowe's refrigeration units and began shipping fresh fruit from New York to the Gulf Coast area, and fresh meat from Galveston, Texas back to New York, but because of Lowe's lack of knowledge about shipping,
7632-502: The late 1920s. These refrigerants were considered — at the time — to be less harmful than the commonly-used refrigerants of the time, including methyl formate, ammonia, methyl chloride, and sulfur dioxide. The intent was to provide refrigeration equipment for home use without danger. These CFC refrigerants answered that need. In the 1970s, though, the compounds were found to be reacting with atmospheric ozone, an important protection against solar ultraviolet radiation, and their use as
7738-473: The majority of the perishable food loads and to push out the old system of the refrigerated rail cars. The widespread use of refrigeration allowed for a vast amount of new agricultural opportunities to open up in the United States. New markets emerged throughout the United States in areas that were previously uninhabited and far-removed from heavily populated areas. New agricultural opportunity presented itself in areas that were considered rural, such as states in
7844-500: The meat trade later implemented refrigerated transport to include vegetables and fruit. The meat packing companies had much of the expensive machinery, such as refrigerated cars, and cold storage facilities that allowed for them to effectively distribute all types of perishable goods. During World War I, a national refrigerator car pool was established by the United States Administration to deal with problem of idle cars and
7950-554: The midst of the Great Depression , President Franklin D. Roosevelt realized that rural areas would continue to lag behind urban areas in both poverty and production if they were not electrically wired. On May 11, 1935, the president signed an executive order called the Rural Electrification Administration , also known as REA. The agency provided loans to fund electric infrastructure in the rural areas. In just
8056-504: The modern beer garden . The rise of lager was entwined with the development of refrigeration , as it made it possible to brew lager year-round (brewing in the summer had previously been banned in many locations across Germany), and efficient refrigeration also made it possible to brew lager in more places and keep it cold until serving. The first large-scale refrigerated lagering tanks were developed for Gabriel Sedelmayr's Spaten Brewery in Munich by Carl von Linde in 1870. Lager uses
8162-426: The most expensive units which they installed on train cars and in branch houses and storage facilities in the more remote distribution areas. By the middle of the 20th century, refrigeration units were designed for installation on trucks or lorries. Refrigerated vehicles are used to transport perishable goods, such as frozen foods, fruit and vegetables, and temperature-sensitive chemicals. Most modern refrigerators keep
8268-531: The most widely used current applications of refrigeration are for air conditioning of private homes and public buildings, and refrigerating foodstuffs in homes, restaurants and large storage warehouses. The use of refrigerators and walk-in coolers and freezers in kitchens, factories and warehouses for storing and processing fruits and vegetables has allowed adding fresh salads to the modern diet year round, and storing fish and meats safely for long periods. The optimum temperature range for perishable food storage
8374-486: The needs of grocers, farmers, and food shippers. Refrigerated railroad cars were introduced in the US in the 1840s for short-run transport of dairy products, but these used harvested ice to maintain a cool temperature. The new refrigerating technology first met with widespread industrial use as a means to freeze meat supplies for transport by sea in reefer ships from the British Dominions and other countries to
8480-565: The ones mentioned above have not been uncommon in history, but what separates these cities from the rest are that these cities are not along some natural channel of transport, or at some crossroad of two or more channels such as a trail, harbor, mountain, river, or valley. These large cities have been developed in areas that only a few hundred years ago would have been uninhabitable. Without a cost efficient way of cooling air and transporting water and food from great distances, these large cities would have never developed. The rapid growth of these cities
8586-417: The pale malt making process. Dreher combined the pale malt making techniques with cold bottom fermentation, using yeast given to him by Sedlmayr. In late 1840, Anton Dreher started renting a cellar to mature his beer under cold conditions, a process that is called "lagering". The resulting beer was clean-tasting and relatively pale for the time thanks to the use of smoke-free "English" hot air kilns, resulting in
8692-468: The pressure of competition from these distant specialized centers. Refrigeration was not limited to meat, fruit and vegetables but it also encompassed dairy product and dairy farms. In the early twentieth century, large cities got their dairy supply from farms as far as 640 kilometres (400 mi). Dairy products were not as easily transported over great distances like fruits and vegetables due to greater perishability. Refrigeration made production possible in
8798-502: The purity of water, from which ice was formed, began to increase in the early 1900s with the rise of germ theory. Numerous media outlets published articles connecting diseases such as typhoid fever with natural ice consumption. This caused ice harvesting to become illegal in certain areas of the country. All of these scenarios increased the demands for modern refrigeration and manufactured ice. Ice producing machines like that of Carre's and Muhl's were looked to as means of producing ice to meet
8904-421: The same vat. On the first of June 2007 Steinlager Pure was released in the New Zealand market. Steinlager "Pure" and Steinlager "Classic" are now sold alongside each other, with Steinlager Pure positioning itself at the premium end of the beer market. It is marketed with Harvey Keitel , Willem Dafoe and Vincent Gallo . Introduced in 2000 as a low alcohol variant of Steinlager. Introduced in 2006, Super Cold
9010-506: The settlement of areas that were not on earlier main transport channels such as rivers, harbors, or valley trails. These new settlement patterns sparked the building of large cities which are able to thrive in areas that were otherwise thought to be inhospitable, such as Houston , Texas, and Las Vegas , Nevada. In most developed countries, cities are heavily dependent upon refrigeration in supermarkets in order to obtain their food for daily consumption. The increase in food sources has led to
9116-404: The shelf life. Meanwhile, dairy farms refrigerate milk year round to avoid spoiling. In the late 19th Century and into the very early 20th Century, except for staple foods (sugar, rice, and beans) that needed no refrigeration, the available foods were affected heavily by the seasons and what could be grown locally. Refrigeration has removed these limitations. Refrigeration played a large part in
9222-563: The size of the refrigerator. However, electric companies that were customers of GE did not benefit from a gas-powered unit. Thus, GE invested in developing an electric model. In 1927, GE released the Monitor Top, the first refrigerator to run on electricity. In 1930, Frigidaire, one of GE's main competitors, synthesized Freon . With the invention of synthetic refrigerants based mostly on a chlorofluorocarbon (CFC) chemical, safer refrigerators were possible for home and consumer use. Freon led to
9328-510: The slump in world wool markets that was heavily affecting New Zealand. After extensive research, he commissioned the Dunedin to be refitted with a compression refrigeration unit for meat shipment in 1881. On February 15, 1882, the Dunedin sailed for London with what was to be the first commercially successful refrigerated shipping voyage, and the foundation of the refrigerated meat industry . The Times commented "Today we have to record such
9434-572: The south and in the west. Shipments on a large scale from the south and California were both made around the same time, although natural ice was used from the Sierras in California rather than manufactured ice in the south. Refrigeration allowed for many areas to specialize in the growing of specific fruits. California specialized in several fruits, grapes, peaches, pears, plums, and apples, while Georgia became famous for specifically its peaches. In California,
9540-412: The specific grain bill used in the beers; paler lagers use unroasted barley and may even add other grains such as rice or corn to lighten the color and provide a crisp, bright finish to the flavour. Darker lagers use roasted grains and malts to produce a more roasted, even slightly burnt, flavour profile. The most common lagers in worldwide production are pale lagers . The flavour of these lighter lagers
9646-452: The spread of diseases such as malaria. He conceived the idea of using his refrigeration system to cool the air for comfort in homes and hospitals to prevent disease. American engineer Alexander Twining took out a British patent in 1850 for a vapour compression system that used ether. The first practical vapour-compression refrigeration system was built by James Harrison , a British journalist who had emigrated to Australia . His 1856 patent
9752-418: The technology did not progress. In fact, consumers that used the icebox in 1910 faced the same challenge of a moldy and stinky icebox that consumers had in the early 1800s. General Electric (GE) was one of the first companies to overcome these challenges. In 1911, GE released a household refrigeration unit that was powered by gas. The use of gas eliminated the need for an electric compressor motor and decreased
9858-561: The temperature between –40 and –20 °C, and have a maximum payload of around 24,000 kg gross weight (in Europe). Although commercial refrigeration quickly progressed, it had limitations that prevented it from moving into the household. First, most refrigerators were far too large. Some of the commercial units being used in 1910 weighed between five and two hundred tons. Second, commercial refrigerators were expensive to produce, purchase, and maintain. Lastly, these refrigerators were unsafe. It
9964-450: The use of Saccharomyces pastorianus , a "bottom-fermenting" yeast that ferments at relatively cold temperatures. Until the 19th century, the German word Lagerbier ( de ) referred to all types of bottom-fermented , cool-conditioned beer in normal strengths. In Germany today, it mainly refers to beers from southern Germany , either " Helles " (pale) or " Dunkles " (dark). Pilsner ,
10070-445: The west far from eastern markets, so much in fact that dairy farmers could pay transportation cost and still undersell their eastern competitors. Refrigeration and the refrigerated rail gave opportunity to areas with rich soil far from natural channel of transport such as a river, valley trail or harbors. "Edge city" was a term coined by Joel Garreau , whereas the term "galactic city" was coined by Lewis Mumford . These terms refer to
10176-419: Was 18 °C (65 °F). They noted that soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about a 6.4 millimetres ( 1 ⁄ 4 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin wrote, "From this experiment, one may see the possibility of freezing
10282-760: Was developed by Ferdinand Carré of France in 1859 and patented in 1860. Carl von Linde , an engineer specializing in steam locomotives and professor of engineering at the Technological University of Munich in Germany, began researching refrigeration in the 1860s and 1870s in response to demand from brewers for a technology that would allow year-round, large-scale production of lager ; he patented an improved method of liquefying gases in 1876. His new process made possible using gases such as ammonia , sulfur dioxide (SO 2 ) and methyl chloride (CH 3 Cl) as refrigerants and they were widely used for that purpose until
10388-537: Was for a vapour-compression system using ether, alcohol, or ammonia. He built a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong , Victoria , and his first commercial ice-making machine followed in 1854. Harrison also introduced commercial vapour-compression refrigeration to breweries and meat-packing houses, and by 1861, a dozen of his systems were in operation. He later entered
10494-403: Was influenced by refrigeration and an agricultural productivity increase, allowing more distant farms to effectively feed the population. Agriculture's role in developed countries has drastically changed in the last century due to many factors, including refrigeration. Statistics from the 2007 census gives information on the large concentration of agricultural sales coming from a small portion of
10600-530: Was later continued after the war. The idle car problem was the problem of refrigeration cars sitting pointlessly in between seasonal harvests. This meant that very expensive cars sat in rail yards for a good portion of the year while making no revenue for the car's owner. The car pool was a system where cars were distributed to areas as crops matured ensuring maximum use of the cars. Refrigerated rail cars moved eastward from vineyards, orchards, fields, and gardens in western states to satisfy Americas consuming market in
10706-468: Was not uncommon for commercial refrigerators to catch fire, explode, or leak toxic gases. Refrigeration did not become a household technology until these three challenges were overcome. During the early 1800s, consumers preserved their food by storing food and ice purchased from ice harvesters in iceboxes. In 1803, Thomas Moore patented a metal-lined butter-storage tub which became the prototype for most iceboxes. These iceboxes were used until nearly 1910 and
10812-412: Was only discovered in the past few decades that eggs needed to be refrigerated during shipment rather than waiting to be refrigerated after arrival at the grocery store. Meats, poultry and fish all must be kept in climate-controlled environments before being sold. Refrigeration also helps keep fruits and vegetables edible longer. One of the most influential uses of refrigeration was in the development of
10918-589: Was picked up by other breweries, most notably Pilsner Urquell Brewery in Bohemia (now part of the Czech Republic ) where Josef Groll produced the first Pilsner beer. The resulting pale coloured, lean and stable beers were very successful and gradually spread around the globe to become the most common form of beer consumed in the world today. Another pale lager variety is Helles , native to Munich. Amber lagers are generally darker in color than pale lagers, often
11024-478: Was put into place as an amendment to the Meat Inspection Act of 1891. This new act focused on the quality of the meat and environment it is processed in. In the early 1930s, 90 percent of the urban population of the United States had electric power , in comparison to only 10 percent of rural homes. At the time, power companies did not feel that extending power to rural areas ( rural electrification ) would produce enough profit to make it worth their while. However, in
11130-511: Was skippered by Peter Blake , won all six legs of the 1989–90 Whitbread Round the World Race , and again in 1995 with Team New Zealand with their " Black Magic " boat, which won the Americas Cup by beating Dennis Conner 's defending boat Stars & Stripes, also known as Young America, 5-nil in the finals' series. Steinlager, along with Toyota , ENZA, TVNZ and Telecom New Zealand , formed
11236-413: Was unwholesome. When meat packing began to take off, consumers became nervous about the quality of the meat for consumption. Upton Sinclair 's 1906 novel The Jungle brought negative attention to the meat packing industry, by drawing to light unsanitary working conditions and processing of diseased animals. The book caught the attention of President Theodore Roosevelt , and the 1906 Meat Inspection Act
