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. 

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 can be direct pitched with great results by sprinkling it onto the surface of the wort in your fermenter. However, proper hydration helps ensure a healthy fermentation and is especially recommended for beer with a starting gravity above 15°P (1.061 SG). To hydrate yeast, first sanitize the yeast pack and a pair of scissors. Boil tap water to sterilize and then cool to 85-95°F (29-35°C). Use 10 grams (0.35 oz) of water per gram of yeast. Sprinkle the yeast onto the water, allow the slurry to stand undisturbed for 20 minutes, and then swirl. Use small amounts of wort to adjust the temperature of the slurry to within 10°F (6°C) of the wort temp before pitching. Ferment between 60-73°F (16-23°C).

Optimum Fermentation Temp: 60-73°F
Flocculation: Medium
Alcohol Tolerance: 10-11% ABV
Attenuation: 75-80%
