Product Overview

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 expression of a beta-glucosidase enzyme LalBrew Köln can promote hop biotransformation and accentuate hop flavor and aroma.

Colder fermentations will be more neutral in character, while warmer fermentations will have more fruit-forward ester profile.
