Definicija

Beer is an alcoholic beverage produced by the brewing and fermentation of starches from cereal grain, most commonly malted barley. Its aroma includes caramel and malty notes, with fruity and flowery notes from yeast and hops.

Miris

Isoamyl acetate has a fruity, banana, sweet, fresh and apple aroma, and its banana-like flavour is a key attribute of Hefeweizen beers. Hops impart floral, fruity or citrus aromas to beer. Hop flavours and aromas may be described as grassy, floral, citrus, spicy, piney, lemony, grapefruit and earthy. Myrcene gives a pungent smell of fresh hops. Yeasty and meaty flavours are often associated with cloudy wheat beers. Dimethyl sulphide is commonly present in lagers and contributes to their characteristic aroma.

Detaljno

What beer is

Beer is one of the oldest and most widely consumed alcoholic drinks in the world. Wheat, maize, rice and oats are also used besides malted barley. Other flavouring agents, such as gruit, herbs or fruits, may be included or used instead of hops. Beer is distributed in bottles and cans, and is commonly available on draught in pubs and bars. A beer hall is a large pub that specializes in beer.

Malt

Malt is any cereal grain that has been made to germinate by soaking in water and then stopped from germinating further by drying with hot air. Malting produces enzymes that convert starches into fermentable sugars. Different roasting times and temperatures produce different colours of malt from the same grain. Darker malts produce darker beers. Caramel malt provides enhanced caramel notes, while roasted malt contributes more roasted or malty flavours.

Hops and yeast

Hops are the green flowers of the hop plant Humulus lupulus. They are used primarily as a bittering, flavouring and stability agent in beer, to which they also give floral, fruity or citrus flavours and aromas. During wort boiling, the humulones in hops are thermally isomerized into iso-alpha acids, which give a bitter flavour to beer. Myrcene, humulene and caryophyllene together make up 80-90% of the essential oil in hops. Top-fermented beers are most commonly produced with Saccharomyces cerevisiae, a top-fermenting yeast. Top-fermenting yeast typically works between 15 and 25 °C, and at these temperatures it produces significant amounts of esters and other secondary flavour and aroma products. Lager is cool-fermented beer, and pale lagers are the most commonly drunk beers in the world.

Chemistry

Beer contains the phenolic acids 4-hydroxyphenylacetic acid, vanillic acid, caffeic acid, syringic acid, p-coumaric acid, ferulic acid and sinapic acid. Tryptophol, tyrosol and phenylethanol are aromatic higher alcohols produced by yeast during the brewing process. Furfural is one of the most prevalent aldehydes in beers. Esters are synthesised during fermentation, and their amount depends on the yeast strain and the fermentation temperature. The Maillard reaction contributes to the browning of malted barley as found in beer. The caramel and malty notes in beer generally arise from Maillard reactions, caramelisation or pyrolysis products.

Istorija

The earliest archaeological evidence of fermentation consists of 13,000-year-old residues of a beer with the consistency of gruel, found at Raqefet Cave near Haifa. The earliest clear chemical evidence of beer produced from barley dates to about 3500-3100 BC, from Godin Tepe in the Zagros Mountains of western Iran. The Babylonian Code of Hammurabi, from about 1750 BC, included laws regulating beer. The Sumerians drank a variety of beers: eight types from barley, 12 types from wheat and 3 from a mixture of grains. When hopped ale from Europe was imported into Britain in the late Middle Ages, it was called beer to differentiate it from the British unhopped ale. Stout was originally the strongest variety of porter, a dark brown beer popular with the street and river porters of eighteenth century London.

Zanimljivosti

The Hymn to Ninkasi, a prayer to the Mesopotamian goddess of beer, contains a recipe for beer. The Sumerians believed that the goddess Ninkasi oversaw the brewing process.

Dobijanje i hemija

Način dobijanja

The process of making beer is brewing. It converts the grain into a sugary liquid called wort and then ferments this into beer using yeast. The first step is mashing, in which malted barley is mixed with hot water in a mash tun. The starches are converted to sugars, and the sweet wort is drained off. Hops are added to the wort during the boil as a source of bitterness, flavour and aroma. The wort is cooled and the yeast is added. The wort is then fermented, often for a week or longer.

Formula: Complex natural mixture (key constituents: ethanol; vanillic acid; caffeic acid; ferulic acid)

U parfemima

Depending on the quantity and on the time and point of addition, the hop gives either a strong or a more subtle hop aroma. In the flavour industry, the Maillard reaction is the basis of many recipes, and flavourists have used it to make artificial flavours.
