Neutral in flavor profile GigaYeast NorCal Ale #1 GY001 creates a crisp beer and allows hops to shine.
GY001 NorCal Ale #1 GigaYeast is a strong attenuator and good flocculation perfectly suited for a large variety of styles. Good choice for high gravity beers.
Attenuation Medium Gravity*
- 76% – 80%
Attenuation High Gravity*
- 78% – 80% (10.5% – 11.0% ABV)
- 18˚C – 25˚C (64˚F – 77˚F)
- Barley Wine
- India Pale Ale
- Pale Ale
- Scotch Ale
* 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).
