Vermont IPA Yeast GY054

Attenuation Medium Gravity*                        78% – 82%

Attenuation High Gravity*                             74% – 76% (10.0% – 10.6% ABV)

Temperature Range:                                   62˚F – 75˚F

Flocculation:                                                  Medium/Low



 From one of the best examples of an east coast IPA.  This yeast attenuates slightly less than NorCal Ale #1 and leaves a beer with more body and a slight fruity ester that is amazing with aromatic hops.  Good choice for high gravity beers and hoppy styles.  Broad temperature range and moderate flocculation make this yeast a versatile house strain.


Representative Styles:

Imperial Pale Ale               American Wheat Beer           

Pale Ale                             Bitter

West Coast Amber            ESB                                                         


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).
