Description
A classic Kölsch strain that ferments cool and finishes dry, crisp and lightly acidic. Esters stay delicate, so the beer reads closer to a lager than an ale while keeping a soft ale mouthfeel. Suits Kölsch, Altbier and any sessionable ale where subtlety matters; it is a touch drier and more refreshing than JY158.
