Lallemand LalBrew® Koln Kolsch-Style Ale Yeast 11g *Discontinued*

****Product being discontinued - limited stock available ****

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.
