British Ale Yeast #2

GY031


Attenuation Medium Gravity* 80% - 82%
Attenuation High Gravity* 72% – 75% (9.3% – 10.0% ABV)
Temperature Range† 64˚F – 75˚F
Flocculation High

Description: From a traditional British brewery. Very flocculent— produces clear beer. GY031 leaves a slightly sweet malty flavor. Flavor profile is nearly neutral at lower fermentation temps. Slight banana/fruit notes appear at higher temps. Perfect for English style pale ales, stouts, porters, bitters browns etc.


Representative Styles: British Ales, Pale/Amber Ale, Barley Wine, Scotch Ale, Bitter, Stout, India Pale 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).
