List of Ale Yeasts

Ale yeast, scientifically known as Saccharomyces cerevisiae, is a top-fermenting yeast known for its distinct characteristics that make it ideal for brewing specific styles of beer. It operates at warmer temperatures, typically between 15-24°C (59-75°F), which is in stark contrast to lager yeast that ferments at cooler temperatures. This warmer fermentation process allows ale yeast to metabolize sugars more quickly, resulting in a faster fermentation process. Ale yeast also produces more esters and phenols during fermentation, which contribute to a wide range of flavors and aromas, including fruity, spicy, and other complex notes.

This yeast strain contrasts with bottom-fermenting lager yeast (Saccharomyces pastorianus) which tends to produce beers with cleaner, more subdued flavors. Ale yeast's flavor complexity makes it suitable for a multitude of beer styles including IPAs, stouts, porters, Belgian ales, wheat beers, and many more. Its ability to create a variety of flavor profiles paired with its efficiency in warmer temperatures, positions ale yeast as a diverse and versatile yeast strain for both traditional and innovative beer brewing.
