KÖLSCH Dry Beer Yeast

KÖLSCH Dry Beer Yeast

A classic yeast strain for Kölsch & Altbier beer styles. This German top fermenting yeast strain produces a clean, neutral ester profile that allows the finished beer to better express noble hops & malt character. Finishes dry with low levels of diacetyl and faint notes of pear, citrus, apple and plum.

Every batch is PCR tested to ensure quality. 

Dosage:
Two 12g sachets are enough to treat a 5–6 gallon batch. Or 50-95 grams per barrel, depending on wort temperature and gravity.

Direct Pitch OR Rehydrate:
KÖLSCH yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels. KÖLSCH yeast is pre-loaded with essential nutrients to ensure a successful, complete fermentation. While not required, some brewers prefer to rehydrate yeast. To hydrate yeast, first, sanitize the yeast brick and scissors. Use 10 grams of sterilized tap water between 85-95°F (29-35°C) mixed with 0.25 grams of FermStart per gram of yeast. Sprinkle yeast on the water. Allow the slurry to stand undisturbed for 20 minutes, then swirl. Use small amounts of wort to adjust to within 10°F (6°C) of wort temperature before pitching. Ferment between 60-73°F (16-23°C).
