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 12g sachets are enough to treat a 5–6 gallon batch. Or 80-120 grams per barrel, depending on wort temperature and gravity.
Direct Pitch or Rehydrate:
BERLIN 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. BERLIN 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 50-59°F (10-15°C).
Optimum Fermentation Temp: 50-59°F
Flocculation: High
Alcohol Tolerance: 10-11% ABV
Attenuation: 75-85%
