GY045 is a bottom fermenting German Lager GigaYeast used in commercial breweries around the world. GY045 German Lager GigaYeast produces a slightly sweeter but clean beer with a malty finish. Perfect for Pilsners, Märzen, Fest bier etc. GY045 GigaYeast may require a diacetyl rest after fermentation.

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.
Lager Yeast are typically fermented at 9˚ – 13˚C (45˚ – 58˚F). If desired, Lager Yeast can be given a “hot start” at 18-20˚C (65-68˚F) and then lowered to the primary temperature after active fermentation begins (10-20 hrs). GigaYeast laboratory is still gathering data on many of our strains. Information provided here may change some in the future.
