Kolsh Style Ale Yeast

Lallemand LalBrew

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 flavour and aroma. Colder fermentations will be more neutral in character, while warmer fermentation will have a more fruit-forward ester profile.
