Description
SafAle™ S-04 is the world-renowned English Ale yeast, prized for its fast fermentation and excellent sedimentation (flocculation) properties. It produces a clean, well-balanced profile with subtle floral and fruity esters, making it the perfect choice for a wide range of British and American ales. S-04 settles out very quickly, forming a firm sediment that results in brilliantly clear beer, even without filtration. Ideal for Bitters, Stouts, Porters, and IPAs.
Brewery Tip: S-04 is a very “hungry” yeast and ferments rapidly; maintain a steady temperature between 64°F and 72°F to prevent the production of harsh fusel alcohols. While it can be sprinkled on top of the wort, rehydrating in 10x its weight of sterile water at 80°F for 15 minutes ensures the highest viable cell count for a vigorous start.
