The British Ale #1 Strain
Versatile house strain from a traditional UK brewery. Strong attenuation over a broad temperature range and low esters make this yeast perfect for a wide variety of styles. GY011 is a strong flocculator that creates a clear beer.
Attenuation Medium Gravity*: 75% – 79%
Attenuation High Gravity*: 73% – 75% (9.0% – 9.4% ABV)
Temperature Range†: 64˚F – 77˚F
Flocculation: High
* 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).
