Czech Pilsner Yeast GY002

Attenuation Medium Gravity*                        75% – 79%

Attenuation High Gravity*                              52% – 55% (6.9% – 7.5% ABV)

Temperature Range:                                  48˚F – 55˚F

Flocculation:                                                 Medium / high


Description:  Bottom fermenting yeast from a world famous Czech pilsner.  Produces a dry, clean beer.   Perfect for pilsner and other lager styles.  This yeast is flocculent and produces a very clear beer.  Robust attenuation in beer up to 16-17˚ Plato.  Moderate to poor attenuation in very high gravity beers (over 20˚ Plato).


Representative Styles:

Pilsners and Lagers



* 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).
