Attenuation Medium Gravity* 74% – 76%

Attenuation High Gravity* 70% – 73% (9.2% – 9.8% ABV)

Temperature Range† 66˚F – 74˚F

Flocculation Low

Description: Belgian Ale yeast from the mother of all Tripels. A balance of fruit and spice with a good malty finish provides a perfect complement for Belgian Ales, Dubbels and Tripels. Perfect for malt forward Belgians. Less esters and phenolics than GY003 and GY014.

Representative Styles: Belgian Ale, Dubbel, Belgian Strong, Tripel, Biere De Garde, Saison

* 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).
