CellarScience GERMAN Weihenstephan Lager

The classic lager strain from Weihenstephan Germany that has been used for generations to produce clean, balanced lagers from pilsners to doppelbocks.

Available in 12g (0.4oz)

Every batch is PCR tested to ensure contamination free yeast. 

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 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. GERMAN 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).
