Notes

Recommended for Saison, farmhouse ale, biere de garde.

Character: Highly attenuative, complex and dry farmhouse character.

A highly attenuative French saison strain that finishes 85 to 90% for a dry farmhouse beer, and it wants a hot 26 to 32 C ferment to fully express and avoid stalling. Give it heat and time; a saison strain that cools mid-ferment leaves a sweet, under-attenuated beer.
