GigaYeast Saison #1 GY018 is a traditional Saison yeast from a French craft brewery. GY018 produces fragrant beer with pepper and fruit notes. Warmer fermentations create more intense flavours. Saison #1 GY018 GigaYeast is perfect for accentuating citrus and fruit flavours. High attenuation rates make a dryer beer than GY027 Saison #2 GigaYeast.
Attenuation Medium Gravity*
Attenuation High Gravity*
- 49% – 53% (6.2% – 6.8% ABV)
- 18˚C – 27˚C (64˚F – 80˚F)
Representative Beer Styles:
- 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 (10-20 hrs). GigaYeast laboratory is still gathering data on many of our strains. Information provided here may change some in the future.
