The majority of compounds in beer come from the metabolic activities of plants and yeast and so are covered by the fields of biochemistry and organic chemistry. [1] The main exception is that beer contains over 90% water and the mineral ions in the water (hardness) can have a significant effect upon the taste. [2]
A more attenuated beer is drier and more alcoholic than a less attenuated beer made from the same wort. Attenuation can be quantified by comparing the specific gravity — the density of a solution, relative to pure water — of the extract before and after fermentation, quantities termed the original and final gravities.
Zymomonas have not been reported in lager breweries due to the low temperatures (8–12 °C) and stringent carbohydrate requirements (able to ferment only sucrose, glucose, and fructose). It is commonly found in cask-conditioned ales where priming sugar is used to carbonate the beer. The optimum growth temperature is 25 to 30 °C.

The Standard Reference Method or SRM [1] is one of several systems modern brewers use to specify beer color. Determination of the SRM value involves measuring the attenuation of light of a particular wavelength (430 nm) in passing through 1 cm of the beer, expressing the attenuation as an absorption and scaling the absorption by a constant (12.7 for SRM; 25 for EBC).
A teaser video months before Liquid Death launched its first products got over 3 million views. Liquid Death’s rise has been meteoric since then. Across 113,000 retailers in the U.S. and UK, it ...
Knowing the amount of extract in 100 grams (3.5 oz) of wort before fermentation and the number of grams of extract in 100 grams (3.5 oz) of beer at its completion, the amount alcohol (in grams) formed during the fermentation can be determined. The formula follows, attributed to Balling [1]: 427
United States standard drinks of beer, malt liquor, wine, and spirits compared. Each contains about 14 grams or 17.7 ml of ethanol. A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol.
