Ale yeast

Ale yeast is a type of yeast used in brewing beer, specifically ales. It’s a single-celled fungus that ferments sugars from malted grains, producing alcohol and carbon dioxide. Ale yeast typically ferments at warmer temperatures than lager yeast, resulting in a rich, complex flavor profile with fruity and estery notes. It is generally an Saccharomyces cerevisiae strain, chosen for its ability to produce bold flavors quickly. Brewers select ale yeast depending on the desired characteristics of the beer, making it a vital element in creating a variety of ale styles.
