Saison Yeast One GY018

Attenuation Medium Gravity*                        81% – 83%

Attenuation High Gravity*                             49% – 53% (6.2% – 6.8% ABV)

Temperature Range:                                   64˚F – 80˚F

Flocculation:                                                  Low



Traditional Saison yeast from a French craft brewery.  Produces fragrant beer with pepper and fruit notes.  Warmer fermentations create more intense flavors.   Perfect for accentuating citrus and fruit flavors.  High attenuation rates make a dryer beer than Saison #2.


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).
