LalBrew® Köln Kolsch Style Dry Yeast
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.

I brewed a 6 gallon high gravity 1.060 Cream Ale, mashed at 148 degrees for 60 minutes. Oxygen was infused into the wort and 2 packs of Koln Kolsh were hydrated and added to the wort. Fermentation temperature was 68 degrees at 8 days the gravity was 1.018, day 12 I think fermentation is complete at 1.012.
LalBrew stated fermentation would take 7 days. The yeast is a slow starter so plan on a 2 week fermentation not the 1 week advertised. I need to cold crash and bottle so I can't give any opinion on taste.
