CellarScience® GERMAN Dry Yeast | Weihenstephan Lager | Premium Beer Yeast

Please select from the following option(s) to see pricing and availability.

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 12g 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.

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
Flocculation: High
Alcohol Tolerance: 9% ABV (WY2124 9%)
Attenuation: 78-85%
Similar Strains: WLP830, WY2124, W-34/70


CellarScience Yeast:
For years liquid yeast has been sold as the higher quality option but times are changing. Yes, 20 years ago dry yeast was made by bread yeast producers and the quality was not as good as liquid yeast. CellarScience is helping to flip that script with a full lineup of high-quality dry yeasts. Cell count and viability is usually higher than commercial liquid yeast pitches, which vary from pouch to pouch and don't ship well. CellarScience yeast can be pitched directly in most batches of wort, offering significant time savings. Yeast that is quick and easy to use, high quality, and available at a reasonable cost adds up to a tremendous value. Quality yeast that doesn't "break the brink".

CellarScience Nutrients:
For high gravity ferments consider rehydrating yeast with CellarScience FermStart yeast hydration nutrient. For high gravity or low nutrient wort, feed your fermentation with CellarScience FermFed DAP Free complex yeast nutrient mix.

OOPs, I meant 12g/5 gallons is my usage at room temp, anybody else use this yeast at room temp?
Laurence Prantner on Jan 23, 2024
BEST ANSWER: It's pretty much identical to SafLager 34/70. As such, you can treat it the same. That's what I have done. Should work well for a room temp Cold IPA or pressure fermented lager. You'll get some mild esters at room temp without pressure fermentation but if your grist has expressive character malts or you are using a lot of hops, you shouldn't notice it. I think the ester profile is light and pleasant but taste is subjective. It is an easy to use and forgiving yeast. Have fun! Hope this helps.

Great house German lager yeast
I prefer to brew 15 gallon German lager yeast batches. Was getting tired of building up yeast starters from single pouches of liquid yeast over the span of a week before brew day. I opted for the 500 gram pack and split into (5) 100 gram vacuum sealed pouches that I keep in my fridge. 2 hours before pitching into wort, sprinkle 100g into 2L of 1.040 SG DME starter and this combination has provided me with a rip roaring fermentation within 6 hours of pitching into 15 gallons of 1.060 oxygenated wort. Ferments clean and crisp. Also, it's less than half the price of name brand 34/70. Bye bye liquid yeast...

Faulty seal on two 500g packages
Didn't try the yeast. I ordered one 500g package--it was slightly soft to the touch on receipt. Put it in cold storage and a couple weeks later it obviously had a leak, package was floppy.

MoreBeer replaced it. Second package, repeat as above. Wasn't ready to brew so put it in cold storage. A few weeks later was ready to brew an floppy package. Had to scramble to get some yeast.

MoreBeer is refunding. I've stored bulk yeast before, bread and brewing yeast, never had this happen. And might not have noticed it if I used it on arrival. Think I'll wait awhile before trying Cellar Science again.

I brewed a Munich Helles and use this yeast. It did very well in the cold fermentation temperatures between 34-38 degrees and after a month the beer came out fantastic with an ABV of 6.4. I’m washing it and starting my own culture of it.

Worked great
Made a 1 qt starter with 1 pkg. Followed with 600 mils of the wort for 24 hours. Got a great pitch, active in 6 hours.

Hot Ferments The Same As W34/70
100% pilsner - 30 minute mash, 30 minute boil -- with current grains, DMS is a myth.
Fermented at 65* with no pressure and it was done in 5 days, raised temp to 70* for 2 days. Dropped crystal clear after 2.5 weeks in the keg with no finings added. This yeast is perfect for quick lagers at ale temps.

Great! Fast and clean fermentation on a large scale.
Pitched 2-500g packs into a 16bbl of 11P wort at 52F. Fermented out clean and fast. Cleaned it up at 63F with little diacetyl and sulphur production.
