This yeast ferments well in dark roast worts. Beers fermented in the lower temperature range produce dry and crisp beers to fruity beers with nice complexity in the upper range. Ester production is enhanced with fermentation temperatures above 64 degrees F (18 C). Flocculation is low to moderate with filtration typically required. Flocculation: Medium. Attenuation: 71-75%. Temperature Range: 62-72°F. Alcohol Tolerance: 10%.
