Flocculation                                             Medium



Clean Fermenting, versatile strain from one of the most famous California Pale Ales.  Neutral flavor profile creates a crisp beer and allows hops to shine.  Strong attenuator and good flocculation perfectly suited for a large variety of styles.  Good choice for high gravity beers.


Representative Styles:

Barley Wine                        Pale Ale

Bitter                                   Scotch Ale

India Pale Ale                     Stout


* 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).
