Description
Built for deep attenuation and quick turnaround, which makes it a natural fit for bigger gravities. It drops out hard at almost any temperature, so it suits warm dry hopping, but chilling too aggressively mid-ferment can flocculate it out early and stall the beer. Rousing the cake will finish things off. A house strain at some very large IPA breweries.
