Character: Clean, lager-like ale character with a slight wine or lager note.
A Kolsch strain that ferments clean and lager-like at ale temperatures, giving the crisp, delicate character of a Cologne Kolsch without needing a lager fridge. Ferment cool and lager it cold for a few weeks for the cleanest result.
