Brewer's yeast (also known as brewers yeast or brewing yeast) can mean any live yeast used in brewing. It can also mean yeast obtained as a by-product of brewing, dried and killed, and used as nutritional yeast. Typical divisions Ascomycota (sac fungi) Saccharomycotina (true yeasts) Taphrinomycotina Schizosaccharomycetes (fission yeasts) Basidiomycota (club fungi) Urediniomycetes Sporidiales Yeasts are a growth form of eukaryotic microorganisms classified in the kingdom Fungi, with approximately 1,500 species described. ...

Nutritional yeast, similar to brewers yeast, is a nutritional supplement popular with vegans and the health conscious who use it as an ingredient in recipes or simply as a condiment. ...
Beer brewing Beer brewers classify yeasts as top-fermenting and bottom-fermenting. This distinction was introduced by the Dane Emil Christian Hansen. The yeast that ferments beer is conventionally divided into two broad classes, top-fermenting and bottom-fermenting. ...
Emil Christian Hansen (May 8, 1842 - August 27, 1909) was a Danish fermentation physiologist. ...
Top-fermenting yeasts (so-called because they float to the top of the beer) can produce higher alcohol concentrations and prefer higher temperatures. An example is Saccharomyces cerevisiae, known to brewers as ale yeast. They produce fruitier, sweeter, ale-type beers. Bottom-fermenting yeasts ferment more sugars, leaving a crisper taste, and work well at low temperatures. Another example is Saccharomyces uvarum, formerly known as Saccharomyces carlsbergensis. They are used in producing lager-type beers. Brewers of Bavarian-style wheat beers often use varieties of Torulaspora delbrueckii, which contribute to the distinctive flavour profile.

Lager is a well attenuated beer brewed in cool conditions using a slow-acting brewers yeast, known as a bottom-fermenting yeast, and then stored (or lagered) for a period in cool conditions to clear away particles and certain flavour compounds to produce a clean taste. ...

Torulaspora delbrueckii is a yeast strain related to Saccharomyces cerevisiae and used for brewing wheat beer. ...
To ensure purity of strain, a 'clean' sample of the yeast is stored in a laboratory environment at refrigerated temperature. After a certain number of fermentation cycles, a full scale propagation is produced from this laboratory sample. Typically, it is grown up in about three or four stages using sterile Brewing wort and oxygen. Typical divisions Ascomycota (sac fungi) Saccharomycotina (true yeasts) Taphrinomycotina Schizosaccharomycetes (fission yeasts) Basidiomycota (club fungi) Urediniomycetes Sporidiales Yeasts are a growth form of eukaryotic microorganisms classified in the kingdom Fungi, with approximately 1,500 species described. ...

Brettanomyces -
Main article: Brettanomyces A genus of "wild" yeast used in brewing lambic. There are three main species: Brettanomyces lambicus; Brettanomyces bruxellensis; and Brettanomyces claussenii, which is found in Britain. [[|Diversity]] Binomial name Trinomial name Type Species Species [[Image: ]] Synonyms Brettanomyces is a single-celled fungus that is important in brewing and winemaking as it is resistant to alcohol so can grow even after fermentation starts. ...

Nutritional yeast Due to its rapid metabolism, yeast contains a high concentration of the B vitamins, whose functions are related to metabolism, as well as other minerals and cofactors required for growth. It can therefore serve as a good dietary supplement of these nutrients. "Brewer's yeast" can also refer loosely to any nutritional yeast. S. cerevisiae is the usual species for this purpose.[1] Structure of the coenzyme adenosine triphosphate, a central intermediate in energy metabolism. ...
The B vitamins are eight water-soluble vitamins that play important roles in cell metabolism. ...

Side effects have not been reported from the use of brewer’s yeast, although allergies to it exist in some people. It is not related to Candida albicans fungus, which causes yeast infection.
Because it contains a highly biologically active form of chromium, supplementation with brewer’s yeast could potentially enhance the effects of drugs for diabetes (e.g., insulin or other blood sugar-lowering agents) and possibly lead to hypoglycemia. Therefore, people with diabetes taking these medications should supplement with chromium or brewer’s yeast only under the supervision of a doctor.
Saccharomyces cerevisiae is registered in Europe under the name Saccharomyces boulardii [citation needed], though the manufacturer states that S. boulardii is not the same as brewer’s yeast (S. cerevisiae). It is marketed as a probiotic supplement for the treatment of diarrhoea and Clostridium difficile colitis. There is a case report [citation needed] of a person with severely impaired immune function who, after receiving treatment with S. boulardii, developed an invasive fungal infection identified as S. cerevisiae. People with severe impairment of the immune system should therefore not take brewer’s yeast or S. boulardii unless supervised by a doctor. Probiotics are dietary supplements containing potentially beneficial bacteria or yeasts. ...

Certain medicines may interact with brewer’s yeast. Refer to drug interactions for a list of those medicines.
