There is evidence that beer was produced at Göbekli Tepe during the Pre-Pottery Neolithic (around 8500 BC to 5500 BC ). The earliest clear chemical evidence of beer produced from barley dates to about 3500–3100 BC , from
565-470: A brittle spike ; upon maturity, the spikelets separate, facilitating seed dispersal . Domesticated barley has nonshattering spikelets, making it much easier to harvest the mature ears. The nonshattering condition is caused by a mutation in one of two tightly linked genes known as Bt 1 and Bt 2 ; many cultivars possess both mutations. The nonshattering condition is recessive , so varieties of barley that exhibit this condition are homozygous for
678-416: A daily ration of four to five litres of beer, which served as both nutrition and refreshment and was crucial to the pyramids' construction. Some of the earliest Sumerian writings contain references to beer; examples include a prayer to the goddess Ninkasi , known as "The Hymn to Ninkasi", which served as both a prayer and a method of remembering the recipe for beer in a culture with few literate people, and
791-539: A degree that brewers of pale ale add gypsum in a process known as Burtonisation . The starch source provides the fermentable material and determines the strength and flavour of the beer. The most common starch source used in beer is malted grain. Grain is malted by soaking it in water, allowing it to begin germination , and then drying the partially germinated grain in a kiln. Malting produces enzymes that convert starches into fermentable sugars. Different roasting times and temperatures produce different colours of malt from
904-431: A dense head and a creamy mouthfeel . In the 1980s, Guinness introduced the beer widget , a nitrogen-pressurised ball inside a can which creates a moderately dense, tight head. This approximates the effect of serving from a keg, at least for a British-style beer which does not have a specially large head. Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed " real ale " by

In traditional taxonomy, different forms of barley were classified as different species based on morphological differences. Two-row barley with shattering spikes (wild barley) was named Hordeum spontaneum . Two-row barley with nonshattering spikes
1582-408: A non-profit UK beer organisation, has set a temperature standard range of 12°–14 °C (53°–57 °F) for cask ales to be served. Beer is consumed out of a variety of vessels, such as a glass, a beer stein , a mug, a pewter tankard , a beer bottle or a can; or at music festivals and some bars and nightclubs, from a plastic cup. The shape of the glass from which beer is consumed can influence

The Andes in South America has Chicha , made from germinated maize (corn); while the indigenous peoples in Brazil have Cauim , a traditional drink made since pre-Columbian times by chewing manioc so that an enzyme ( amylase ) present in human saliva can break down the starch into fermentable sugars; this is similar to Masato in Peru . Beers made from bread , among
1921-442: A seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic ( PET ) bottles are used by some breweries. The temperature of a beer has an influence on a drinker's experience; warmer temperatures reveal
2034-531: A secondary carbohydrate source, such as maize (corn), rice, wheat, or sugar, often termed an adjunct , especially when used alongside malted barley. Less widely used starch sources include millet , sorghum , and cassava root in Africa; potato in Brazil; and agave in Mexico. Water is the main ingredient, accounting for 93% of beer's weight. The level of dissolved bicarbonate influences beer's finished taste. Due to

Fulk with the Eddaic Bergelmir . In English folklore , the figure of John Barleycorn in the folksong of the same name is a personification of barley, and of the alcoholic beverages made from it: beer and whisky. In
2599-404: A source of bitterness, flavour, and aroma. The longer the hops are boiled, the more bitterness they contribute, but the less hop flavour and aroma remain. The wort is cooled and the yeast is added. The wort is then fermented, often for a week or longer. The yeast settles, leaving the beer clear. During fermentation, most of the carbon dioxide is allowed to escape through a trap . The carbonation
2712-411: A store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption. Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeast—either by being unfiltered, or by being filtered and then reseeded with fresh yeast. Many beers are sold in cans, though there is considerable variation in

Each spikelet has a long thin awn (to 160 mm (6.3 in) long), making the ears look tufted. The spikelets are in clusters of three. In six-row barley, all three spikelets in each cluster are fertile; in two-row barley, only the central one
3277-401: Is a form of domesticated barley with an easier-to-remove hull . Naked barley is an ancient food crop, but a new industry has developed around uses of selected hulless barley to increase the digestibility of the grain, especially for pigs and poultry. Hulless barley has been investigated for several potential new applications as whole grain, bran, and flour. In 2022, world production of barley
3390-516: Is a key ingredient in beer and whisky production. Two-row barley is traditionally used in German and English beers. Six-row barley was traditionally used in US beers , but both varieties are in common usage now. Distilled from green beer, Scottish and Irish whisky are made primarily from barley. About 25% of American barley is used for malting, for which barley is the best-suited grain. Accordingly, barley

In Eastern and Central Europe, barley is used in soups and stews such as ričet . In Africa, where it is a traditional food plant, it has the potential to improve nutrition, boost food security, foster rural development, and support sustainable landcare. The six-row variety bere
3842-621: Is at best mixed. Barley grains were once used for measurement in England, there being nominally three or four barleycorns to the inch. By the 19th century, this had been superseded by standard inch measures. In ancient Mesopotamia , barley was used as a form of money, the standard unit of weight for barley, and hence of value, being the shekel . In the Old English poem Beowulf , and in Norse mythology , Scyld Scefing (the second name meaning "with

A 2016 systematic review and meta-analysis found that moderate ethanol consumption brought no mortality benefit compared with lifetime abstention from ethanol consumption. Some studies have concluded that drinking small quantities of alcohol (less than one drink in women and two in men, per day) is associated with a decreased risk of heart disease , stroke , diabetes mellitus , and early death. Some of these studies combined former ethanol drinkers and lifelong abstainers into

4746-573: Is often assessed by its malting enzyme content. Barley wine is a style of strong beer from the English brewing tradition. An 18th-century alcoholic drink of the same name was made by boiling barley in water, then mixing the barley water with white wine, borage , lemon and sugar. In the 19th century, a different barley wine was prepared from recipes of ancient Greek origin. Nonalcoholic drinks such as barley water and roasted barley tea have been made by boiling barley in water. In Italy, roasted barley
4859-454: Is often increased either by transferring the beer to a pressure vessel and introducing pressurised carbon dioxide or by transferring it before the fermentation is finished so that carbon dioxide pressure builds up inside the container. The basic ingredients of beer are water; a starch source, usually malted barley ; a brewer's yeast to produce the fermentation; and a flavouring such as hops . A mixture of starch sources may be used, with
4972-425: Is often replaced with forced carbonation. Beer is distributed in bottles and cans, and is commonly available on draught in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries . The strength of modern beer is usually around 4% to 6% alcohol by volume (ABV). Some of

In 2022, barley was fourth among grains in quantity produced, 155 million tonnes , behind maize , wheat, and rice . Globally, 70% of barley production is used as animal feed , while 30% is used as a source of fermentable material for beer , or further distilled into whisky , and as a component of various foods. It
5311-535: Is sometimes used as coffee substitute, caffè d'orzo (barley coffee). Some 70% of the world's barley production is used as livestock feed, for example for cattle feeding in western Canada. In 2014, an enzymatic process was devised to make a high-protein fish feed from barley, suitable for carnivorous fish such as trout and salmon . Barley straw has been placed in mesh bags and floated in fish ponds or water gardens to help prevent algal growth without harming pond plants and animals. The technique's effectiveness

Some viruses, such as barley yellow dwarf virus , vectored by the rice root aphid , can cause serious crop injury. For durable disease resistance, quantitative resistance is more important than qualitative resistance . The most important foliar diseases have corresponding resistance gene regions on all chromosomes of barley. A large number of molecular markers are available for breeding of resistance to leaf rust, powdery mildew, Rhynchosporium secalis , Pyrenophora teres f. teres , Barley yellow dwarf virus , and
5537-424: Is the sole commercial use of hops . The flower of the hop vine acts as a flavouring and preservative agent in nearly all beer made today. The flowers themselves are often called "hops". The first historical mention of the use of hops in beer dates from 822 AD in monastery rules written by Adalard of Corbie , though widespread cultivation of hops for use in beer began in the thirteenth century. Before then, beer

The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period of hours to days to "drop" (clear) again, as well as to fully condition the beer . At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass. Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that
8475-696: The city of Plzeň in the present-day Czech Republic . The modern pale lager is light in colour due to use of coke for kilning, which gives off heat with little smoke. Dark beers are usually brewed from a pale malt or lager malt base with a small proportion of darker malt added to achieve the desired shade. Other colourants—such as caramel—are also widely used to darken beers. Very dark beers, such as stout , use dark or patent malts that have been roasted longer. Some have roasted unmalted barley. Beer ranges from less than 3% alcohol by volume (abv) to around 14% abv, though this strength can be increased to around 20% by re-pitching with champagne yeast, and to 55% ABVby
8588-449: The container from which it is dispensed, and served without the use of extraneous carbon dioxide ". It is applied to both bottle conditioned and cask conditioned beers. As for the types of top-fermented beers, pale ale predominantly uses pale malt. It is one of the world's major beer styles and includes India pale ale (IPA). Mild ale has a predominantly malty palate. It is usually dark, with an abv of 3% to 3.6%. Wheat beer
8701-426: The development of artificial refrigeration and by the 1870s, was spread in those countries that concentrated on brewing pale lager. Chilling beer makes it more refreshing, though below 15.5 °C (60 °F) the chilling starts to reduce taste awareness and reduces it significantly below 10 °C (50 °F). Beer served unchilled—either cool or at room temperature—reveal more of their flavours. Cask Marque ,
8814-591: The domestication of barley, in the form of cultivars that cannot reproduce without human assistance, comes from Mesopotamia, specifically the Jarmo region of modern-day Iraq, around 9,000–7,000 BC. Domestication changed the morphology of the barley grain substantially, from an elongated shape to a more rounded spherical one. Wild barley has distinctive genes , alleles , and regulators with potential for resistance to abiotic or biotic stresses ; these may help cultivated barley to adapt to climatic changes. Wild barley has
8927-653: The earliest forms of the drink, are Sahti in Finland, Kvass in Russia and Ukraine , and Bouza in Sudan. 4000 years ago fermented bread was used in Mesopotamia. Food waste activists got inspired by these ancient recipes and use leftover bread to replace a third of the malted barley that would otherwise be used for brewing their craft ale. Beer is measured and assessed by colour, by strength and by bitterness. The strength of modern beer
9040-551: The earliest writings mention the production and distribution of beer: the Code of Hammurabi included laws regulating it, while "The Hymn to Ninkasi ", a prayer to the Mesopotamian goddess of beer, contains a recipe for it. Beer forms part of the culture of many nations and is associated with social traditions such as beer festivals , as well as activities like pub crawling , pub quizzes , and pub games . In early forms of English and in
9153-466: The fifth century AD. This grain, along with a cool climate that permitted storage, produced a civilization that was able to raise great armies. It is made into a flour product called tsampa that is still a staple in Tibet. In medieval Europe, bread made from barley and rye was peasant food, while wheat products were consumed by the upper classes. Spikelets are arranged in triplets which alternate along
9266-707: The freeze-distilling process. The alcohol content of beer varies by local practice or beer style. The pale lagers that most consumers are familiar with fall in the range of 4–6%, with a typical ABVof 5%. The customary strength of British ales is quite low, with many session beers being around 4% abv. In Belgium, some beers, such as table beer are of such low alcohol content (1%–4%) that they are served instead of soft drinks in some schools. The weakest beers are described as 'alcohol-free' , typically containing 0.05% ABV; this compares to low alcohol beers which may contain 1.2% ABV or less, and conventional beers which average 4.4% ABV. The strength of beers has climbed during
9379-568: The initiates, prepared from barley and herbs, mentioned in the Homeric hymn to Demeter . The goddess's name may have meant "barley-mother", incorporating the ancient Cretan word δηαί (dēai), "barley". The practice was to dry the barley groats and roast them before preparing the porridge, according to Pliny the Elder 's Natural History . Tibetan barley has been a staple food in Tibetan cuisine since
9492-418: The largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Busch when it acquired Royal Grolsch , the brewer of Dutch brand Grolsch. In 2008, when InBev (the second-largest) bought Anheuser-Busch (the third-largest), the new Anheuser-Busch InBev company became again the largest brewer in the world. As of 2020 , according to the market research firm Technavio, AB InBev was the largest brewing company in
9605-521: The later years of the 20th century. Vetter 33, a 10.5% ABV (33 degrees Plato , hence Vetter "33") doppelbock , was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus , by the Swiss brewer Hürlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% |BV. Since then, some brewers have used champagne yeasts to increase
9718-662: The mutant allele . Domestication in barley is followed by the change of key phenotypic traits at the genetic level. The wild barley found currently in the Fertile Crescent may not be the progenitor of the barley cultivated in Eritrea and Ethiopia , indicating that it may have been domesticated separately in eastern Africa. Archaeobotanical evidence shows that barley had spread throughout Eurasia by 2,000 BC. Genetic analysis demonstrates that cultivated barley followed several different routes over time. By 4200 BC domesticated barley had reached Eastern Finland. Barley has been grown in
9831-730: The natural production of esters and other byproducts, resulting in a "cleaner"-tasting beer. With improved modern yeast strains, most lager breweries use only short periods of cold storage, typically no more than 2 weeks. Some traditional lagers are still stored for several months. Lambic , a beer of Belgium , is naturally fermented using wild yeasts, rather than cultivated. Many of these are not strains of brewer's yeast ( Saccharomyces cerevisiae ) and may have significant differences in aroma and sourness. Yeast varieties such as Brettanomyces bruxellensis and Brettanomyces lambicus are common in lambics. In addition, other organisms such as Lactobacillus bacteria produce acids which contribute to
9944-407: The perception of the beer and can define and accent the character of the style. Breweries offer branded glassware intended only for their own beers as a marketing promotion, as this increases sales of their product. The pouring process has an influence on a beer's presentation. The rate of flow from the tap or other serving vessel, tilt of the glass, and position of the pour (in the centre or down
10057-441: The proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing spoilage) and have
10170-875: The range of flavours in a beer but cooler temperatures are more refreshing. Most drinkers prefer pale lager to be served chilled, a low- or medium-strength pale ale to be served cool, while a strong barley wine or imperial stout to be served at room temperature. Beer writer Michael Jackson proposed a five-level scale for serving temperatures: well chilled (7 °C or 45 °F) for "light" beers (pale lagers); chilled (8 °C or 46 °F) for Berliner Weisse and other wheat beers; lightly chilled (9 °C or 48 °F) for all dark lagers, altbier and German wheat beers; cellar temperature (13 °C or 55 °F) for regular British ale , stout and most Belgian specialities ; and room temperature (15.5 °C or 60 °F) for strong dark ales (especially trappist beer ) and barley wine . Drinking chilled beer began with
10283-530: The result is often a beer with slightly "fruity" compounds resembling apple, pear, pineapple, banana , plum, or prune, among others. After the introduction of hops into England from Flanders in the 15th century, "ale" came to mean an unhopped fermented brew, while "beer" meant a brew with an infusion of hops. The term ' real ale ' was coined by the Campaign for Real Ale (CAMRA) in 1973 for "beer brewed from traditional ingredients, matured by secondary fermentation in
10396-435: The role of yeast in fermentation was understood, fermentation involved wild or airborne yeasts. A few styles, such as lambics , rely on this method today, but most modern fermentation adds pure yeast cultures . Some brewers add clarifying agents or finings to beer, which typically precipitate (collect as a solid) out along with protein solids, and are found only in trace amounts in the finished product. This process makes
10509-708: The same grain. Darker malts produce darker beers. Nearly all beers use barley malt for most of the starch, as its fibrous hull remains attached to the grain during threshing. After malting, barley is milled, which finally removes the hull, breaking it into large pieces. These pieces remain with the grain during the mash and act as a filter bed during lautering , when sweet wort is separated from insoluble grain material. Other grains, including wheat, rice, oats , and rye , and less frequently, corn and sorghum may be used. Some brewers have produced gluten-free beer , made with sorghum, for those who cannot consume gluten -containing grains like wheat, barley, and rye. Flavouring beer
10622-416: The side) into the glass all influence the result, such as the size and longevity of the head, lacing (the pattern left by the head as it moves down the glass as the beer is drunk), and the release of carbonation . A beer tower or portable beer tap is sometimes used in bars and restaurants to allow a group of customers to serve themselves. The device consists of a tall container with a cooling mechanism and
10735-647: The site of Godin Tepe in the Zagros Mountains of western Iran . Beer is recorded in the written history of ancient Egypt , and archaeologists speculate that beer was instrumental in the formation of civilizations. Approximately 5000 years ago, workers in the city of Uruk (modern day Iraq) were paid by their employers with volumes of beer. During the building of the Great Pyramids in Giza, Egypt , each worker got
10848-454: The song, John Barleycorn is represented as suffering attacks, death, and indignities that correspond to the various stages of barley cultivation, such as reaping and malting; but he is revenged by getting the men drunk: "And little Sir John and the nut-brown bowl / Proved the strongest man at last." The folksong " Elsie Marley " celebrates an alewife of County Durham with lines such as "And do you ken Elsie Marley, honey? / The wife that sells
10961-560: The sourness. Around the world, many traditional and ancient starch-based drinks are classed as beer. In Africa, there are ethnic beers made from sorghum or millet , such as Oshikundu in Namibia and Tella in Ethiopia. Kyrgyzstan also has a beer made from millet; it is a low alcohol, somewhat porridge-like drink called "Bozo". Bhutan , Nepal, Tibet and Sikkim also use millet in Chhaang ,
11074-503: The strongest beer by a Dutch brewery in July 2010. Draught (also spelled "draft") beer from a pressurised keg using a lever-style dispenser and a spout is the most common method of dispensing in bars around the world. A metal keg is pressurised with carbon dioxide (CO 2 ) gas which drives the beer to the dispensing tap or faucet. Some beers may be served with a nitrogen/carbon dioxide mixture. Nitrogen produces fine bubbles, resulting in
11187-411: The strongest beer made is Schorschbräu's 2011 Schorschbock 57 with 57,5% ABV. It was preceded by The End of History , a 55% Belgian ale , made by BrewDog in 2010. The same company had previously made Sink The Bismarck! , a 41% ABV IPA , and Tactical Nuclear Penguin , a 32% ABV Imperial stout . Each of these beers are made using the eisbock method of fractional freezing , in which a strong ale
11300-513: The strongest variety of porter , a dark brown beer popular with the street and river porters of eighteenth century London. Lager is cool-fermented beer. Pale lagers are the most commonly drunk beers in the world. Many are of the " pilsner " type. The name "lager" comes from the German "lagern" for "to store", as brewers in Bavaria stored beer in cool cellars during the warm summer months, allowing
11413-491: The sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale . Hops further contribute floral, citrus, and herbal aromas and flavours. They have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms, and aids in " head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops
11526-619: The three main theories are that the word originates in Proto-Germanic * beuzą (putatively from Proto-Indo-European * bʰeusóm ), meaning ' brewer's yeast , beer dregs'; that it is related to the word barley , or that it was somehow borrowed from Latin bibere 'to drink'. Christine Fell , in Leeds Studies in English (1975), suggests that the Old English/Norse word bēor did not originally denote ale or beer, but
11639-574: The west to Tibet in the east. A study of genome-wide diversity markers found Tibet to be an additional center of domestication of cultivated barley. The earliest archaeological evidence of the consumption of wild barley , Hordeum spontaneum , comes from the Epipaleolithic at Ohalo II at the southern end of the Sea of Galilee , where grinding stones with traces of starch were found. The remains were dated to about 23,000 BC. The earliest evidence for
11752-468: The world, with Heineken second, CR Snow third, Carlsberg fourth, and Molson Coors fifth. A microbrewery , or craft brewery , produces a limited amount of beer. The maximum amount of beer a brewery can produce and still be classed as a 'microbrewery' varies by region and by authority; in the US, it is 15,000 US beer barrels (1.8 megalitres; 390 thousand imperial gallons; 460 thousand US gallons)
11865-412: Was bere . This survives in the north of Scotland as bere ; it is used for a strain of six-row barley grown there. Modern English barley derives from the Old English adjective bærlic , meaning "of barley". The word barn derives from Old English bere-aern meaning "barley-store". The name of the genus is from Latin hordeum , barley, likely related to Latin horrere , to bristle. Barley
11978-412: Was 155 million tonnes, led by Russia accounting for 15% of the world total (table). France, Germany, and Canada were secondary producers. Worldwide barley production was fourth among grains, following maize (1.2 billion tonnes), wheat (808 million tonnes), and rice (776 million tonnes). Barley is a crop that prefers relatively low temperatures, 15 to 20 °C (59 to 68 °F) in the growing season; it
12091-940: Was by hand with sickles or scythes ; in developed countries, harvesting is mechanised with combine harvesters . Among the insect pests of barley are aphids such as Russian wheat aphid , caterpillars such as of the armyworm moth , barley mealybug , and wireworm larvae of click beetle genera such as Aeolus . Aphid damage can often be tolerated, whereas armyworms can eat whole leaves. Wireworms kill seedlings, and require seed or preplanting treatment. Serious fungal diseases of barley include powdery mildew caused by Blumeria graminis , leaf scald caused by Rhynchosporium secalis , barley rust caused by Puccinia hordei , crown rust caused by Puccinia coronata , various diseases caused by Cochliobolus sativus , Fusarium ear blight , and stem rust ( Puccinia graminis ). Bacterial diseases of barley include bacterial blight caused by Xanthomonas campestris pv. translucens . Barley
12204-550: Was different from every brewer. What they did not contain was hops , as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by abbess Hildegard of Bingen . In 1516, William IV, Duke of Bavaria adopted the Reinheitsgebot (purity law), perhaps the oldest food-quality regulation still in use in the 21st century, according to which the only allowed ingredients of beer are water, hops , and barley- malt . Beer produced before
12317-553: Was flavoured with other plants such as grains of paradise or alehoof . Combinations of aromatic herbs, berries, and even wormwood were combined into aflavouring mixture known as gruit . Some beers today, such as Fraoch' by the Scottish Heather Ales company use plants other than hops for flavouring. and Cervoise Lancelot by the French Brasserie-Lancelot company, Hops contribute a bitterness that balances
12430-430: Was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers may have contained fruits, honey, numerous types of plants, spices, and other substances such as narcotic herbs. This mixture was called gruit, where if some were improperly heated could cause hallucinations. The mixture of gruit
12543-428: Was named as H. distichon , six-row barley with nonshattering spikes as H. vulgare (or H. hexastichum ), and six-row with shattering spikes as H. agriocrithon . Because these differences were driven by single-gene mutations, coupled with cytological and molecular evidence, most recent classifications treat these forms as a single species, H. vulgare . Hulless or "naked" barley ( Hordeum vulgare var. nudum )
12656-583: Was not used to saccharify the rice (amylolytic fermentation); the rice was probably prepared for fermentation by chewing or malting . During the Vedic period in Ancient India , there are records of the consumption of the beer-like sura . Xenophon noted that during his travels, beer was being produced in Armenia . Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it
12769-628: Was used as currency. The Sumerian language had a word for barley, akiti . In ancient Mesopotamia , a stalk of barley was the primary symbol of the goddess Shala . Rations of barley for workers appear in Linear B tablets in Mycenaean contexts at Knossos and at Mycenaean Pylos . In mainland Greece, the ritual significance of barley possibly dates back to the earliest stages of the Eleusinian Mysteries . The preparatory kykeon or mixed drink of
