LalBrew Premium Series - Koln Style Ale Yeast x 11g (Kolsch)

Technical Data Sheet - Koln

LalBrew Köln is ideal for brewing traditional Kölsch-style beers and other neutral ales. The neutral character of this strain accentuates delicate hop aromas while imparting subtle fruity esters. 

Through the expression of a β-glucosidase enzyme, Köln can promote hop biotransformation and accentuate hop flavor and aroma. Colder fermentations will be more neutral in character, while warmer fermentation will have a more fruit-forward ester profile
