SafAle™ K-97 is a world-class German ale yeast strain prized for its ability to produce clean, crisp beers with a characteristic dense foam head. This 500g bulk brick is the ideal solution for commercial breweries. K-97 is the definitive choice for brewing authentic German Kolsch, Altbier, and Belgian-style Wheat beers. It offers high attenuation and a very clean ester profile, allowing the delicate malt and hop aromatics to shine while providing the high flocculation required for brilliantly clear finishes.
