GY005 : GOLDEN GATE LAGER
Attenuation Medium Gravity* 79% – 83%
Attenuation High Gravity* 57% – 60% (7.5% – 8.1% ABV)
Temperature Range† 55˚F – 70˚F
Description: Lager yeast used to create the California Common beer style. Ferments unusually high for a lager strain and still retains a lager sensibility (up to 68˚F). This yeast leaves a slightly sweeter beer than our other lager yeast— perfect for creating a subtle, malty undertone against a clean lager background. Creates a moderate amount of sulfide under some conditions that will dissipate with a short rest. Fermentations at traditional lager temperatures may be slow. Recommended 55˚- 68˚F.
Representative Styles: California Common, Cream Ale, Stout
* 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).
