Saison Yeast Two GY027

Attenuation Medium Gravity*                        79% – 83%

Attenuation High Gravity*                              44% – 47% (5.5% – 6.0% ABV)

Temperature Range:                                   64˚F – 80˚F

Flocculation:                                                  Low



From a traditional farmhouse Saison.  Creates the fruity/spicy aroma traditional to the style.  Warmer fermentation temps result in more intense flavor.  Produces a tartness not found in most of our yeast and a slightly sweeter beer than GY018 (Saison #1).


Representative Styles:

Saison                               Farmhouse Ale

Belgian Ale                        Biere De Garde


* 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).
