Irish Ale Yeast Activator - Wyeast 1084 - 4.25 oz.

SKU: Y1084

Wyeast 1084 is an ideal ingredient in the production of stouts, porters, wee heavy, ambers and red ales.


This yeast ferments extremely well in dark roast worts. Beers fermented in the lower temperature range produce dry and crisp beers to fruity beers with a nice compexity in the upper range. Ester production is enhanced with fermentation temperatures above 64F (18 C). Flocculation is low to moderate with filtration typically required.
