* Medium Gravity is 14˚ – 16˚Plato / 1.057 - 1.065 SG. High Gravity is 23˚- 25˚Plato 1.096 - 1.106. 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 20 - 21˚C (68˚ – 70˚F) and then lower or raise temp as desired. Lager Yeast are typically fermented at 7 - 14˚C (45˚ – 58˚F). If desired, Lager Yeast can be given a “hot start” at 18-20˚F (65-68˚F) and then lowered to the primary temperature after active fermentation begins (10-20 hours). GigaYeast laboratory is still gathering data on many of our strains. Information provided here may change some in the future.
