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

A popular yeast strain with a Berlin lineage that is famous for producing amazing lagers with soft malt character and balanced esters. Like all CellarScience yeast, BERLIN 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. BERLIN 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:
BERLIN 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
Attenuation: 78-85%
Similar Strains: WLP820, WY2206, S-23

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.

I've used this twice,, and I get a very sweet apple flavor. Fermentation is perfect, kept low, and a large pitch. Its not acetylalde at all either. Not the clean flavor I was looking for. Interesting to say the least.
