Beer Brewing Classes



From one of the oldest Kolsch breweries in Koln. Fermenting under 65°F produces a very clean, crisp beer with a touch of ester. Perfect for Klsch or any style where a dry, clean profile is desired. GY021 produces a moderate amount of sulfide that will dissipate completely.

Recommended Styles:

Kolsch Pale Ale

Alt India Pale Ale

Cream Ale Amber


* Medium Gravity is 14° 16°Plato. High Gravity is 23°- 25°Plato.

* The working temperature range represents the range at which fermentation for a given strain produces a typical attenuation- not necessarily the ideal temperature for your particular beer style. As a rule of thumb, start ale yeast fermentation at 68° 70°F and then lower or raise temp as desired. Lager Yeast are typically fermented at 45° 58°F. If desired, Lager Yeast can be given a hot start at 65-68°F and then lowered to the primary temperature after active fermentation begins (10-20hrs).
