*  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).
