Quebec Abbey Ale GigaYeast GY077 is from one of the first breweries in North America to create a successful line of traditional Abbey style ales.

This Belgian ale yeast creates a malt forward beer with subtle fruity esters and a very small amount of clove notes.

Robust attenuation makes this yeast an excellent choice for low or high gravity beers where a slightly sweet malty finish is desired. Perfect for the Belgian Dubbel and Tripel styles.

Attenuation Medium Gravity* 

  • 79% – 83%
Attenuation High Gravity*
  • 75% – 78% (10% – 10.3% ABV)
Temperature Range†

  • Medium
Representative Styles: 
  • Belgian Ale
  • Dubbel
  • Belgian Strong

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