GY134 Kveik #1 GigaYeast is a traditional Norwegian Kveik yeast that can be fermented at 29˚ – 38˚C (85˚F – 100˚F) for fast fermentations and no off flavors.

GigaYeast have found a 15 Plato (1.061 specific gravity) wort attenuates to 74% - 78% in as little as 48 hours at 32˚C / 90˚F.

Subtle notes of citrus fruit make this yeast an excellent choice for clean hop-forward IPAs and Pale Ales with citrus hop additions.

Attenuation Medium Gravity*    74% – 78%
Attenuation High Gravity*          74% – 78%
Temperature Range†                   27˚ – 38˚C (80˚F – 100˚F)
Flocculation                                  Medium

Representative Styles: 

  • Norwegian Farmhouse
  • Pale Ale
  • IPA
  • NEIPA
  • Saison

* Attenuation was measured after 8 days with Ale yeast at 21˚C / 70˚F and Lager yeast at 10˚C / 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 20˚ – 22˚C (68˚F – 72˚F) and then lower or raise temp as desired. Lager Yeast are typically fermented at 7˚ – 14˚C (45˚F – 58˚F). If desired, Lager Yeast can be given a “hot start” at 18˚ – 20˚C (65˚F – 68˚F) and then lowered to the primary temperature after active fermentation begins (10-20 hrs).
