103-458: Espresso ( / ɛ ˈ s p r ɛ s oʊ / , Italian: [eˈsprɛsso] ) is a concentrated form of coffee produced by forcing hot water under high pressure through finely ground coffee beans. Originating in Italy, espresso has become one of the most popular coffee-brewing methods worldwide. It is characterized by its small serving size, typically 25–30 ml, and its distinctive layers:

206-414: A 9th-century Ethiopian goatherd, first observed the coffee plant after seeing his flock energized by chewing on the plant. This legend does not appear before 1671, first being related by Antoine Faustus Nairon, a Maronite professor of Oriental languages and author of one of the first printed treatises devoted to coffee, De Saluberrima potione Cahue seu Cafe nuncupata Discurscus (Rome, 1671), indicating

309-479: A broader coffee culture that values relationships with growers and importers and the craftsmanship involved in making specific coffee-based drinks. The mention of brands such as Synesso, La Marzocco, and Slayer, known for their top-notch equipment, highlights the differences between traditional espresso machines and super-automatic machines to achieve a complete coffee preparation. The significance of espresso machines in coffee culture today lies in their central role in

412-456: A central role in coffee shop culture and the third-wave coffee movement , which emphasizes artisanal production and high-quality beans. Some English dictionaries translate espresso as 'pressed-out', but the word also conveys the senses of expressly for you and quickly : The words express , expres and espresso each have several meanings in English, French and Italian. The first meaning

515-537: A coffee berry and lays 35 to 50 eggs. Inside, the offspring grow, mate, and then emerge from the commercially ruined berry to disperse, repeating the cycle. Pesticides are mostly ineffective because the beetle juveniles are protected inside the berry nurseries, but they are vulnerable to predation by birds when they emerge. When groves of trees are nearby, the American yellow warbler , rufous-capped warbler , and other insectivorous birds have been shown to reduce by 50 percent

618-411: A coffee machine called the "Revolver Coffee Machine" that featured most of the key elements of modern espresso machines. Angelo Moriondo is often erroneously credited for inventing the beverage, since he patented a steam-driven coffee beverage making device in 1884 (No. 33/256), probably the first Italian coffee machine similar to other French and English 1800s steam-driven coffee machines. The device

721-484: A coffee machine capable of producing 2,000 cups of coffee per hour. He presented this machine, called "café express", at the Paris Exposition of 1855. However, the machine did not use steam to directly force water through the coffee but rather used steam indirectly, it brewed coffee a potful at a time and the device was too complicated to have any impact on public. In 1878, German inventor Gustav Adolf Kessel patented

824-438: A creamy consistency). As a result of the pressurized brewing process, the flavors and chemicals in a typical cup of espresso are very concentrated. Espresso contains more caffeine per unit volume than most coffee beverages, but as its usual serving size of 25–30 ml (1 US oz) is much smaller than other coffee drinks, the overall caffeine content of a single "serving" of espresso is generally lower than that of other coffees. While

927-564: A cupful. It is composed of water and the fruit from a bush called bunnu. Thriving trade brought many goods, including coffee, from the Ottoman Empire to Venice. From there it was introduced to the rest of Europe. Coffee became more widely accepted after it was deemed a Christian beverage by Pope Clement VIII in 1600, despite appeals to ban the "Muslim drink". The first European coffee house opened in Venice in 1647. The Dutch East India Company

1030-532: A dark body topped with a lighter-colored foam called crema . Espresso machines use pressure to extract a highly concentrated coffee with a complex flavor profile in a short time, usually 25–30 seconds. The result is a beverage with a higher concentration of suspended and dissolved solids than regular drip coffee, giving espresso its characteristic body and intensity. Despite the stronger taste profile, espresso typically contains fewer milligrams of caffeine than an equal serving of drip-brewed coffee. Espresso serves as

1133-409: A darker roast is generally preferred. Farther north, the trend moves toward slightly lighter roasts, while outside Italy a wide range is popular. The main variables in a shot of espresso are the "size" and "length". This terminology is standardized, but the precise sizes and proportions vary substantially. Cafés may have a standardized shot (size and length), such as "triple ristretto ", only varying

1236-530: A doppio shot. In espresso-based drinks in America, particularly larger milk-based drinks, a drink with three or four shots of espresso will be called a "triple" or "quad", respectively. The length of the shot can be ristretto (or stretto ) (reduced), normale or standard (normal), or lungo (long): these may correspond to a smaller or larger drink with the same amount of ground coffee and same level of extraction or to different length of extraction. Proportions vary, and

1339-612: A grammar and usage guide. Assisted in the research by Francis, who died in 1918 of tuberculosis contracted (1915–16) whilst serving with the British Expeditionary Force in the First World War (1914–1918), Henry dedicated the first edition of the Dictionary to his late brother: I think of it as it should have been, with its prolixities docked, its dullnesses enlivened, its fads eliminated, its truths multiplied. He had

1442-520: A mulch. They are especially appreciated by worms and acid-loving plants such as blueberries. Climate change may significantly impact coffee yields during the 21st century, such as in Nicaragua and Ethiopia which could lose more than half of the farming land suitable for growing (Arabica) coffee. As of 2016, at least 34% of global coffee production was compliant with voluntary sustainability standards such as Fairtrade , UTZ , and 4C (The Common Code for

1545-498: A nimbler wit, a better sense of proportion, and a more open mind, than his twelve-year-older partner; and it is a matter of regret that we had not, at a certain point, arranged our undertakings otherwise than we did.   ... This present book accordingly contains none of his actual writing; but, having been designed in consultation with him, it is the last fruit of a partnership that began in 1903 with our translation of Lucian . The first edition of A Dictionary of Modern English Usage

1648-400: A sentence with a preposition , rules on the placement of the word only , and rules distinguishing between which and that . He classified and condemned every cliché , in the course of which he coined and popularised the terms battered ornament , vogue words , and worn-out humour , while defending useful distinctions between words whose meanings were coalescing in practice, thereby guiding

1751-595: A small workshop in Via Parini, Milan. A detailed discussion of the spread of espresso is given in ( Morris 2007 ). In Italy, the rise of espresso consumption was associated with industrialization and urbanization , notably in Turin, Genoa, and Milan, in northwest Italy. Italians also spread espresso culture into their East African colonies, Italian Somalia and Italian Eritrea. Under the Fascist regime , coffee consumed standing up

1854-549: A student of Balliol College from Crete named Nathaniel Conopios of Crete. Oxford's Queen's Lane Coffee House , established in 1654, is still in existence today. Coffee was introduced in France in 1657 and in Austria and Poland after the 1683 Battle of Vienna , when coffee was captured from supplies of the defeated Turks. When coffee reached North America during the Colonial period, it

1957-428: A third are beetles , and over a quarter are bugs . Some 20 species of nematodes , 9 species of mites, and several snails and slugs also attack the crop. Birds and rodents sometimes eat coffee berries, but their impact is minor compared to invertebrates. In general, arabica is the more sensitive species to invertebrate predation overall. Each part of the coffee plant is assailed by different animals. Nematodes attack

2060-537: Is "almost certainly the first Italian bar machine that controlled the supply of steam and water separately through the coffee". In 1887, the British inventors James Childs and Charles John Jones made significant improvements to espresso machine design, inventing the first portafilter and developing a system that allowed for the consecutive use of water and steam. Fourteen years later, in 1901, Italian inventor Luigi Bezzera devised and patented several improved versions of

2163-517: Is a beverage brewed from roasted, ground coffee beans . Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks. Coffee production begins when the seeds of the Coffea plant's fruits (coffee cherries) are separated to produce unroasted green coffee beans . The beans are roasted and then ground into fine particles. Coffee

2266-405: Is a layer of dense foam that forms on top of the drink. It consists of emulsified oils in the ground coffee turned into a colloid , which does not occur in other brewing methods. Crema is produced when water placed under very high pressure dissolves more carbon dioxide, a gas present inside the coffee that is produced during the roasting process. Espresso is served on its own, and is also used as

2369-419: Is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso , French press , caffè latte , or already-brewed canned coffee ). Sugar, sugar substitutes, milk, and cream are often added to mask the bitter taste or enhance

2472-475: Is generally in places where the humidity is very high. An Asian coffee known as kopi luwak undergoes a peculiar process made from coffee berries eaten by the Asian palm civet , passing through its digestive tract, with the beans eventually harvested from feces . Coffee brewed from this process is among the most expensive in the world, with bean prices reaching $ 160 per pound or $ 30 per brewed cup. Kopi luwak coffee

2575-536: Is induced by the fungal pathogen Gibberella xylarioides . It can affect several Coffea species, and could potentially threaten production worldwide. Mycena citricolor , American leaf spot, is a fungus that can affect the whole coffee plant. It grows on leaves, resulting in leaves with holes that often fall from the plant. It is a threat primarily in Latin America. Over 900 species of insect have been recorded as pests of coffee crops worldwide. Of these, over

2678-548: Is more common for an electric pump to generate the pressure. Tamping down the coffee promotes the water's even penetration through the grounds. This process produces a thicker beverage by extracting both solid and dissolved components. The technical parameters outlined by the Italian Espresso National Institute for making a "certified Italian espresso" are: Any bean or roasting level can be used to produce authentic espresso. For example, in southern Italy,

2781-471: Is not used in the original Italian and is strictly incorrect, although it is common." The Oxford English Dictionary and Merriam-Webster call it a variant spelling. The Online Etymology Dictionary calls expresso a variant of espresso . The Oxford Dictionary of American Usage and Style (2000) describes the spelling expresso as "wrong", and specifies espresso as the only correct form. The third edition of Fowler 's Modern English Usage , published by

2884-661: Is now prepared for drinking. The coffee beans were procured by the Yemenis from the Ethiopian Highlands via coastal Somali intermediaries, and cultivated in Yemen. By the 16th century, the drink had reached the rest of the Middle East and North Africa, later spreading to Europe. The two most commonly grown coffee bean types are C. arabica and C. robusta . Coffee plants are cultivated in over 70 countries , primarily in

2987-403: Is often simpler and less labor-intensive, and a wet process method, which incorporates batch fermentation, uses larger amounts of water in the process, and often yields a milder coffee. Then they are sorted by ripeness and color, and most often the flesh of the berry is removed, usually by machine, and the seeds are fermented to remove the slimy layer of mucilage still present on the seed. When

3090-464: Is often used for a double, with solo and triplo being more rarely used for singles and triples. The single shot is the traditional shot size, being the maximum that could easily be pulled on a lever machine. Single baskets are sharply tapered or stepped down in diameter to provide comparable depth to the double baskets and, therefore, comparable resistance to water pressure. Most double baskets are gently tapered (the "Faema model"), while others, such as

3193-414: Is said to have a uniquely rich, slightly smoky aroma and flavor with hints of chocolate, resulting from the action of digestive enzymes breaking down bean proteins to facilitate partial fermentation . In Thailand, black ivory coffee beans are fed to elephants whose digestive enzymes reduce the bitter taste of beans collected from dung. These beans sell for up to $ 1,100 a kilogram ($ 500 per lb), achieving

3296-441: Is seen as the more formal denomination, café solo (alone, without milk) is the usual way to ask for it at an espresso bar. Some sources state that expresso is an incorrect spelling, including Garner's Modern American Usage . While the 'expresso' spelling is recognized as mainstream usage in some American dictionaries, some cooking websites call the 'x' variant illegitimate. Oxford Dictionaries online states: "The spelling expresso

3399-402: Is suspended solids, while the third is the layer of gas bubbles or foam. The dispersion of very small oil droplets is perceived in the mouth as creamy. This characteristic of espresso contributes to what is known as the body of the beverage. These oil droplets preserve some of the aromatic compounds that are lost to the air in other coffee forms, enhancing the strong flavor of espresso. The crema

3502-477: Is to do with the idea of "expressing" ("pressing out of") or squeezing the flavour from the coffee using the pressure of the steam. The second meaning is to do with speed, as in a train. Finally there is the notion of doing something "expressly" for a person ... The first Bezzera and Pavoni espresso machines in 1906 took 45 seconds to make a cup of coffee, one at a time, expressly for you. Modern espresso, using hot water under pressure, as pioneered by Gaggia in

3605-399: Is to raise seedlings in nurseries that are then planted outside after six to twelve months. Coffee is often intercropped with food crops, such as corn, beans, or rice during the first few years of cultivation as farmers become familiar with its requirements. Coffee plants grow within a defined area between the tropics of Cancer and Capricorn, termed the bean belt or coffee belt. In 2020,

3708-413: Is used as an inexpensive substitute for arabica in many commercial coffee blends. Good quality robusta beans are used in traditional Italian espresso blends to provide a full-bodied taste and a better foam head (known as crema ). Additionally, robusta is less susceptible to disease than arabica and can be cultivated in lower altitudes and warmer climates where arabica does not thrive. The robusta strain

3811-466: Is vulnerable, hastened the uptake of the resistant robusta. The pathogen and results in light, rust-colored spots on the undersides of coffee plant leaves. It grows exclusively on the leaves of coffee plants. Coffee leaf rust is found in virtually all countries that produce coffee. Beans from different countries or regions can usually be distinguished by differences in flavor, aroma, body, and acidity. These taste characteristics are dependent not only on

3914-481: The Oxford University Press in 1996, noted that the form espresso "has entirely driven out the variant expresso (which was presumably invented under the impression that it meant 'fast, express')". The first prototype was created in France in 1822 by Louis Bernard Rabaut. Although the result remains unknown, the experiment was proven by the drawings. In 1843, Edouard Loysel de Santais, a Frenchman, built

4017-545: The Rainforest Alliance have led a campaign for 'shade-grown' and organic coffees , which can be sustainably harvested. Shaded coffee cultivation systems show greater biodiversity than full-sun systems, and those more distant from continuous forest compare rather poorly to undisturbed native forest in terms of habitat value for some bird species. Coffee production uses a large volume of water. On average it takes about 140 litres (37  US gal ) of water to grow

4120-632: The coffee industry have also pointed to its negative impact on the environment and the clearing of land for coffee-growing and water use. The word coffee entered the English language in 1582 via the Dutch koffie , borrowed from the Ottoman Turkish kahve ( قهوه ), borrowed in turn from the Arabic qahwah ( قَهْوَة ). Medieval Arab lexicographers traditionally held that the etymology of qahwah meant 'wine', given its distinctly dark color, and

4223-635: The 18th century, coffee consumption declined in Britain, giving way to tea drinking. Tea was simpler to make, and had become cheaper with the British conquest of India and the tea industry there. During the Age of Sail, seamen aboard ships of the British Royal Navy made substitute coffee by dissolving burnt bread in hot water. The Frenchman Gabriel de Clieu took a coffee plant to the French territory of Martinique in

The first coffee seeds were smuggled out of the Middle East by Sufi Baba Budan from Yemen to India during the time. Before then, all exported coffee was boiled or otherwise sterilized. Portraits of Baba Budan depict him as having smuggled seven coffee seeds by strapping them to his chest. The first plants from these smuggled seeds were planted in Mysore . Coffee had spread to Italy by 1600 and then to

4841-855: The Caribbean in the 1720s, from which much of the world's cultivated arabica coffee is descended. Coffee thrived in the climate and was conveyed across the Americas. Coffee was cultivated in Saint-Domingue (now Haiti) from 1734, and by 1788 it supplied half the world's coffee. The conditions that the enslaved people worked in on coffee plantations were a factor in the soon to follow Haitian Revolution . The coffee industry never fully recovered there. Meanwhile, coffee had been introduced to Brazil in 1727, although its cultivation did not gather momentum until independence in 1822. After this time, massive tracts of rainforest were cleared for coffee plantations, first in

4944-473: The Coffee Community). Coffee berries are traditionally selectively picked by hand, which is labor-intensive as it involves the selection of only the berries at the peak of ripeness. More commonly, crops are strip picked, where all berries are harvested simultaneously regardless of ripeness by person or machine. After picking, green coffee is processed by one of two types of method—a dry process method which

As specialty coffee developed in the 1980s (following earlier developments in the 1970s and even 1960s), an indigenous artisanal coffee culture developed, with espresso instead positioned as an upmarket drink. The third-wave coffee movement encompasses espresso machines as

It can be made with various types of coffee beans and roast levels, allowing for a wide range of flavors and strengths. The quality of an espresso is influenced by factors such as the grind size, water temperature, pressure, and the barista's skill in tamping the coffee grounds. While espresso contains more caffeine per unit volume than most coffee beverages, its typical serving size results in less caffeine per serving compared to larger drinks such as drip coffee. The cultural significance of espresso extends beyond its consumption, playing

5562-428: The base for various other coffee drinks, including caffè latte , cappuccino , caffè macchiato , caffè mocha , flat white , and americano . Espresso is made by forcing very hot water under high pressure through finely ground compacted coffee. There is no universal standard defining the process of extracting espresso, but several published definitions attempt to constrain the amount and type of ground coffee used,

5665-505: The berries have only one; these are called peaberries . Arabica berries ripen in six to eight months, while robusta takes nine to eleven months. Coffea arabica is predominantly self-pollinating, and as a result, the seedlings are generally uniform and vary little from their parents. In contrast, Coffea canephora , and C. liberica are self-incompatible and require outcrossing . This means that useful forms and hybrids must be propagated vegetatively . Cuttings, grafting, and budding are

5768-441: The clearing of trees and increased use of fertilizer and pesticides, which damage the environment and cause health problems. Unshaded coffee plants grown with fertilizer yield the most coffee, although unfertilized shaded crops generally yield more than unfertilized unshaded crops: the response to fertilizer is much greater in full sun. While traditional coffee production causes berries to ripen more slowly and produce lower yields,

The global coffee industry is massive and worth $ 495.50 billion as of 2023. In the same year, Brazil was the leading grower of coffee beans, producing 35% of the world's total, followed by Vietnam and Colombia. While coffee sales reach billions of dollars annually worldwide, coffee farmers disproportionately live in poverty. Critics of

6489-433: The exact caffeine content of any coffee drink will vary, a typical 30 millilitres (1 US fluid ounce) serving of espresso contains approximately 65 milligrams of caffeine, but a typical 240 millilitres (8 US fluid ounces) serving of drip coffee contains 150–200 mg of caffeine. The three dispersed phases in espresso are what make the beverage unique. The first dispersed phase is an emulsion of oil droplets. The second phase

Of the two main species grown, arabica coffee (from C. arabica ) is generally more highly regarded than robusta coffee (from C. canephora ). Robusta coffee tends to be bitter and has less flavor but a better body than arabica. For these reasons, about three-quarters of coffee cultivated worldwide is C. arabica . Robusta strains also contain about 40–50% more caffeine than arabica. Consequently, this species

Starting in the 1970s, many farmers switched their production method to sun cultivation, in which coffee is grown in rows under full sun with little or no forest canopy. This causes berries to ripen more rapidly and bushes to produce higher yields, but requires

7725-474: The number of coffee berry borers in Costa Rica coffee plantations. Originally, coffee was grown in the shade of trees that provided a habitat for many animals and insects. Remnant forest trees were used for this purpose, but many species have been planted as well. These include leguminous trees of the genera Acacia , Albizia , Cassia , Erythrina , Gliricidia , Inga , and Leucaena , as well as

7828-477: The number of shots in espresso-based drinks such as lattes, but not changing the extraction . Changing between a double and a triple requires changing the filter basket size, while changing between ristretto, normale , and lungo may require changing the grind. The size can be a single, double, or triple, using a proportional amount of ground coffee, roughly 7, 14, and 21 grams; correspondingly sized filter baskets are used. The Italian multiplier term doppio

7931-771: The past participle of the Italian verb esprimere , itself derived from the Latin exprimere , which means 'to express', and refers to the process by which hot water is forced under pressure through ground coffee; x is not considered part of the standard Italian alphabet . Italians commonly refer to espresso simply as caffè ( lit.   ' coffee ' ), espresso being the ordinary coffee to order. The same happens in Portugal ( café ), with some regional variations ( bica in Lisbon and cimbalino traditionally in Porto ). In Spain, while café expreso

8034-405: The plants is transpired straight back into the local environment through the plants' leaves (especially for cooling effects); broad estimates aside, consequential margins vary considerably based on details of local geography and horticultural practice. Coffee is often grown in countries where there is a water shortage, such as Ethiopia . Used coffee grounds may be used for composting or as

8137-406: The preparation of espresso-based drinks. Espresso machines are not merely tools for brewing coffee; they are symbols of craftsmanship, quality, and dedication to coffee making. Espresso is generally thicker than coffee brewed by other methods, with a viscosity similar to that of warm honey. This is due to the higher concentration of suspended and dissolved solids and the crema on top (a foam with

8240-406: The primary export and economic backbone for African countries like Uganda, Burundi, Rwanda, and Ethiopia, as well as many Central American countries. Several species of shrub of the genus Coffea produce the berries from which coffee is extracted. The two main species commercially cultivated are Coffea canephora (predominantly a form known as 'robusta') and C. arabica . C. arabica ,

8343-479: The quality of the coffee is allegedly superior. In addition, the traditional shaded method provides living space for many wildlife species. Proponents of shade cultivation say environmental problems such as deforestation, pesticide pollution, habitat destruction, and soil and water degradation are the side effects of the practices employed in sun cultivation. The American Birding Association , Smithsonian Migratory Bird Center , National Arbor Day Foundation , and

8446-457: The rest of Europe, Indonesia, and the Americas. In 1583, Leonhard Rauwolf , a German physician, gave this description of coffee after returning from a ten-year trip to the Near East: A beverage as black as ink, useful against numerous illnesses, particularly those of the stomach. Its consumers take it in the morning, quite frankly, in a porcelain cup passed around and from which each one drinks

8549-542: The roots, coffee borer beetles burrow into stems and woody material, and the foliage is attacked by over 100 species of larvae (caterpillars) of butterflies and moths. Mass spraying of insecticides has often proven disastrous, as predators of the pests are more sensitive than the pests themselves. Instead, integrated pest management has developed, using techniques such as targeted treatment of pest outbreaks, and managing crop environment away from conditions favoring pests. Branches infested with scale are often cut and left on

8652-399: The same shot stopped at different times (which could result in an under- or over-extracted shot), but have the grind adjusted (finer for ristretto, coarser for lungo) to achieve the target volume. A significantly longer shot is the caffè crema , which is longer than a lungo, ranging in size from 120–240 ml (4.2–8.4 imp fl oz; 4.1–8.1 US fl oz), and brewed in

8755-422: The same way, with a coarser grind. Passing too much water through the ground coffee can add other, potentially unpleasant flavors to the espresso. Home espresso machines have increased in popularity with the general rise of interest in espresso. Today, a wide range of home espresso equipment can be found in kitchen and appliance stores, online vendors, and department stores. The first espresso machine for home use

8858-538: The speaker and the writer away from illogical sentence construction, and the misuse of words. In the entries "Pedantic Humour" and "Polysyllabic Humour" Fowler mocked the use of arcane words (archaisms) and the use of unnecessarily long words. Widely and often cited, A Dictionary of Modern English Usage is renowned for its witty passages, such as: Before writing A Dictionary of Modern English Usage , Henry W. Fowler and his younger brother, Francis George Fowler (1871–1918), wrote and revised The King's English (1906),

8961-413: The story is likely apocryphal. Another legend attributes the discovery of coffee to a Sheikh Omar. Starving after being exiled from Mokha (a port city in what is now Yemen), Omar found berries. After attempting to chew and roast them, Omar boiled them, which yielded a liquid that revitalized and sustained him. The earliest credible evidence of coffee drinking or knowledge of the coffee tree appears in

9064-665: The taste of the beverage by changing the coffee bean both physically and chemically. The bean decreases in weight as moisture is lost and increases in volume, causing it to become less dense. The density of the bean also influences the strength of the coffee and the requirements for packaging. The actual roasting begins when the temperature inside the bean reaches approximately 200 °C (392 °F), though different varieties of seeds differ in moisture and density and therefore roast at different rates. During roasting, caramelization occurs as intense heat breaks down starches , changing them to simple sugars that begin to brown, which darkens

9167-399: The temperature and pressure of the water, and the rate of extraction. Generally, one uses an espresso machine to make espresso. The act of producing a shot of espresso is often called "pulling" a shot, originating from lever espresso machines, with which a barista pulls down a handle attached to a spring-loaded piston, which forces hot water through the coffee at high pressure. However, it

9270-452: The usual methods of vegetative propagation. On the other hand, there is great scope for experimentation in search of potential new strains. The traditional method of planting coffee is to place 20 seeds in each hole at the beginning of the rainy season . This method loses about 50% of the seeds' potential, as about half fail to sprout. A more effective process of growing coffee, used in Brazil,

9373-517: The vicinity of Rio de Janeiro and later São Paulo. Brazil went from having essentially no coffee exports in 1800 to being a significant regional producer in 1830, to being the largest producer in the world by 1852. In 1910–1920, Brazil exported around 70% of the world's coffee, Colombia, Guatemala, and Venezuela exported 15%, and Old World production accounted for less than 5% of world exports. Many countries in Central America took up cultivation in

9476-471: The volume (and low density) of crema makes volume-based comparisons difficult (precise measurement uses the mass of the drink). Typically, ristretto is half the volume of normale , and lungo is double to triple the normale volume. For a double shot (14 grams of dry coffee), a normale uses about 60 ml of water. A double ristretto, a common form associated with espresso, uses half the amount of water, about 30 ml. Ristretto, normale , and lungo may not simply be

9579-424: The world production of green coffee beans was 175,647,000 60 kg bags, led by Brazil with 39% of the total, followed by Vietnam, Colombia, and Indonesia. Brazil is the largest coffee exporting nation, accounting for 15% of all world exports in 2019. As of 2021, no synthetic coffee products are publicly available but multiple bioeconomy companies have reportedly produced first batches that are highly similar on

9682-409: The world's most expensive coffee, three times costlier than palm civet coffee beans. The next step in the process is the roasting of green coffee. Coffee is usually sold in a roasted state, and with rare exceptions, such as infusions from green coffee beans, coffee is roasted before it is consumed. It can be sold roasted by the supplier, or it can be home roasted . The roasting process influences

9785-467: Was derived from the verb qahiya ( قَهِيَ ), ' to have no appetite '. The word qahwah most likely meant 'the dark one', referring to the brew or the bean; qahwah is not the name of the bean, which are known in Arabic as bunn and in Cushitic languages as būn . Semitic languages have the root qhh , 'dark color', which became a natural designation for the beverage. Its cognates include

9888-716: Was first collected in 1890 from the Lomani River , a tributary of the Congo River, and was conveyed from the Congo Free State (now the Democratic Republic of the Congo) to Brussels to Java around 1900. From Java, further breeding resulted in the establishment of robusta plantations in many countries. In particular, the spread of the devastating coffee leaf rust (caused by the fungal pathogen Hemileia vastatrix ), to which arabica

9991-526: Was first exported from Ethiopia to Yemen by Somali merchants from Berbera and Zeila in modern-day Somaliland, which was procured from Harar and the Abyssinian interior. According to Captain Haines, who was the colonial administrator of Aden (1839–1854), Mokha historically imported up to two-thirds of its coffee from Berbera-based merchants before the coffee trade of Mokha was captured by British-controlled Aden in

10094-545: Was initially not as successful as in Europe, as alcoholic beverages remained more popular. During the Revolutionary War, the demand for coffee increased so much that dealers had to hoard their scarce supplies and raise prices dramatically; this was also due to the reduced availability of tea from British merchants, and a general resolution among many Americans to avoid drinking tea following the 1773 Boston Tea Party . During

10197-646: Was not the heaviest coffee-drinking nation at the time (Belgium, the Netherlands and Nordic countries all had comparable or higher levels of per capita consumption), due to its sheer size, it was already the largest consumer of coffee in the world by 1860, and, by 1920, around half of all coffee produced worldwide was consumed in the US. Coffee has become a vital cash crop for many developing countries. Over one hundred million people in developing countries have become dependent on coffee as their primary source of income. It has become

10300-439: Was published in 1926, and then was reprinted with corrections in 1930, 1937, 1954, and in 2009, with an introduction and commentary by the linguist David Crystal . The second edition, titled Fowler's Modern English Usage , was published in 1965, revised and edited by Ernest Gowers . The third edition, The New Fowler's Modern English Usage , was published in 1996, edited by Robert Burchfield ; and in 2004, Burchfield's revision of

10403-537: Was subject to price controls , encouraging the "stand at a bar" culture. In the English-speaking world, espresso became popular, particularly in the form of cappuccino , owing to the tradition of drinking coffee with milk and the exotic appeal of the foam; in the United States, this was more often in the form of lattes, with or without flavored syrups added. In the United Kingdom, espresso grew in popularity in

10506-599: Was the Gaggia Gilda. Soon afterwards, similar machines such as the Faema Faemina, FE-AR La Peppina, and VAM Caravel followed suit, with similar form factors and operational principles. These machines still have a small but dedicated share of fans. Until the advent of the first small electrical pump-based espresso machines, such as the Gaggia Baby and Quickmill 810, home espresso machines were not widely adopted. In recent years,

10609-576: Was the first to import coffee on a large scale. The Dutch later grew the crop in Java and Ceylon. The first exports of Indonesian coffee from Java to the Netherlands occurred in 1711. Through the efforts of the British East India Company , coffee also became popular in England. In a diary entry of May 1637, John Evelyn recorded tasting the drink at Oxford in England, where it had been brought by
