Description
 

The classic lager strain from Weihenstephan Germany that has been used for generations to produce clean, balanced lagers from pilsners to doppelbocks. Like all CellarScience yeast, GERMAN is eligible for direct pitch straight into your wort. CellarScience provides 15g of yeast per sachet, which is up to 9% more than any other brand of dry yeast. Every batch of yeast is PCR tested to ensure quality. GERMAN has been selling to pro breweries for awhile but was just recently packaged down to sachets for homebrewers.

Dosage:
Two sachets are enough to treat a 5–6 gallon batch. When calculating for larger batches, use at a rate of 2.5–4 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.

Direct Pitch or Rehydrate:
GERMAN 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 54-62°F (12-17°C).

Optimum Fermentation Temp: 54-62°F

Alcohol Tolerance: 9% ABV (WY2124 9%)

5 of 5 Dry German Yeast May 31, 2026
Reviewer: Willy  
I have used it several times and it
Performs very well. Clean and
Efficient like 34/70. I doubt I
Could differentiate between this
And 34/70. That is a compliment.

Giving it a try and will compare it to my usual yeast for lagers, 34/70. Currently in the fermenter bubbling away.

Very hardy yeast. I use this for my summer lager and October fest beers. It’s the best I’ve used so far.
