This strain is a classic, true top cropping yeast strain from a traditional brewery in Cologne, Germany. Beers will exhibit some of the fruity character of an ale, with a clean lager like profile. It produces low or no detectable levels of diacetyl. This yeast may also be used to produce quick-conditioning pseudo-lager beers and ferments well at cold 55-60°F (13-16°C) range. This powdery strain results in yeast that remain in suspension post fermentation. It requires filtration or additional settling time to produce bright beers.

Flocculation: low
Attenuation: 73-77%
Temperature Range: 56-70° F (13-21° C)
Alcohol Tolerance: approximately 10% ABV

American Wheat or Rye Beer
Berliner Weisse
Bière de Garde
Cream Ale
Düsseldorf Altbier
Fruit Beer
Northern German Altbier
Spice, Herb, or Vegetable Beer

For best results we always recommend ordering an ice pack with your liquid yeast.

Less than expected
This yeast supplier seems to have a great reputation. I however have had little success with any of their products. I think shipping with the grains perhaps is to much to ask as most arrive already fully expanded. Slow fermentation and fall sort of complete fermentation for a five gallon brew. Had higher expectations.

Comparing kolsch yeast
I wanted to compare this yeast to G03 Dieter.
The same recipe was used for both beers. However, I did get more flavors from G03. Malty and refreshing with a hint of noble hops. The beer cleared extremely faster. And it fermented faster as well.

Wyeast 2565 would be my second choice if Dieter is not available.

Used this yeast to make a clone of New Glarus Spotted Cow cream ale. Worked perfectly - didnt need to do a starter.

My favorite kolsch stain...Fermented fine low at 59F. Water profile seemed most similar to what I’ve drank in Köln

More Beer to the rescue
My homebrew club, the Southern Maine Homebrewers did a collaboration brew with Geary's Brewing Co. Portland and this was the perfect yeast for our 'authentic' Kölsch brew. The packets came on time, at the best price and the yeast was so fresh i easily made a 2 gallon starter for the 45 gallon batch. I recommend More Beer to anyone looking for the best price of home brew supplies.

If you don't want to or can't ferment at 48 to 52 degrees, this yeast makes a great alternative. I have used it many, many times for pseudo lagers. Primary ferment at 60 to 65 and then lager as normal.

Good Yeast for a Lager like beer using ale yeast
Very active yeast. It blew the cork out of my fermentor in the first 18 ish hours. Brew smelled wonderful when I checked it and found the cork out. Still to taset the brew. That is still a ways away.
