White Labs German Ale/Kolsch. From a small brewpub in Cologne, Germany, this yeast works great in Kolsch and Alt style beers. Good for light beers like blond and honey. Accentuates hop flavors, similar to WLP001. The slight sulfur produced during fermentation will disappear with age and leave a super clean, lager like ale. Flocculation: medium, attenuation: 72-78%, 65-69 deg F. Does not ferment well below 62 deg F.
