A variant yeast known as Saccharomyces cerevisiae var. diastaticus is a beer spoiler which can cause secondary fermentations in packaged products. [ 68 ] In May 2013, the Oregon legislature made S. cerevisiae the official state microbe in recognition of the impact craft beer brewing has had on the state economy and the state's identity.

In beer, the metabolic waste products of yeast are a significant factor. In aerobic conditions, the yeast will use in the glycolysis the simple sugars obtained from the malting process, and convert pyruvate, the major organic product of glycolysis, into carbon dioxide and water via the cellular respiration. Many homebrewers use this aspect of ...
Saccharomyces is a genus of fungi that includes many species of yeasts. Saccharomyces is from Greek σάκχαρον (sugar) and μύκης (fungus) and means sugar fungus.Many members of this genus are considered very important in food production where they are known as brewer's yeast, baker's yeast and sourdough starter among others.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Old English: Beore 'beer'. In early forms of English and in the Scandinavian languages, the usual word for beer was the word whose Modern English form is ale. [1] The modern word beer comes into present-day English from Old English bēor, itself from Common Germanic, it is found throughout the West Germanic and North Germanic dialects (modern Dutch and German bier, Old Norse bjórr).
Yeast produces two different sulphur compounds regardless of the strain of yeast (H2S, SO2), with the main concern being how concentrated and quick the production is. Optimal yeast selection has ale brewers choosing strands of yeast with low production of H2S overall, as the chemical gives the beer an unappealing smell akin to garlic or burnt ...
A 16th-century brewery Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence ...
