Bavarian Hefe Yeast GY017

Attenuation Medium Gravity*                        77% – 81%

Attenuation High Gravity*                              66% – 69% (8.9% – 9.6% ABV)

Temperature Range:                                   64˚F – 80˚F

Flocculation:                                                   very low



A traditional hefe yeast from one of Bavaria’s oldest breweries.  Robust attenuator that works over a broad range of temperatures and produces the classic banana and clove notes of the German wheat beer style.  Moderate sulfide producer (will dissipate with conditioning). 


Recommended Styles:

Dunkelweizen            Gose

Hefeweizen                Weizenbock


*  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˚ – 70˚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).
