Version 2.77


Brewer's yeast (also known as 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 a dietary supplement for its B vitamin content.

Brewers classify yeasts as top-fermenting and bottom-fermenting. This distinction was introduced by the Dane Emil Christian Hansen. "Top-fermenting yeasts" are so called because they form a foam at the top of the wort during fermentation. They can produce higher alcohol concentrations and prefer higher temperatures, typically 16 to 24 °C (61 to 75 °F), producing fruitier, sweeter, ale-type beers. An example of a top-fermenting yeast is Saccharomyces cerevisiae, known to brewers as ale yeast. "Bottom-fermenting yeasts" are typically used to produce lager-type beers, though can also produce ale-type beers. These yeasts ferment more sugars, leaving a crisper taste, and grow well at low temperatures. An example of bottom fermenting yeast is Saccharomyces pastorianus, formerly known as Saccharomyces carlsbergensis.
