Attenuation Medium Gravity* 74% – 78%

Attenuation High Gravity* 58% – 61% (7.6% – 8.3% ABV)

Temperature Range† 50˚F – 60˚F

Flocculation Medium/Low

Description: Bottom fermenting German yeast used in commercial breweries around the world. Produces a slightly sweeter but clean beer with a malty finish. Perfect for pilsners, märzen, Festbier etc . May require a diacetyl rest after fermentation.

Representative Styles: Lagers, Keller Bier, Märzen, Schwarz Bier, Bock, Pilsner

* Attenuation was measured after 8 days with Ale yeast at 70˚F and Lager yeast at 50˚F. Medium Gravity is 14˚ – 16˚Plato. High Gravity is 23˚- 25˚Plato.

† The working temperature range represents the range at which fermentation for a given strain produces a typical attenuation- not necessarily the ideal temperature for your particular beer style. As a rule of thumb, start ale yeast fermentation at 68˚ – 72˚F and then lower or raise temp as desired. Lager Yeast are typically fermented at 45˚ – 58˚F. If desired, Lager Yeast can be given a “hot start” at 65-68˚F and then lowered to the primary temperature after active fermentation begins (10-20hrs).

GigaYeast laboratory is still gathering data on many of our strains. Information provided here may change some in the future. Please call if you need more info.
