Brewers love this yeast strain for dark beers. Its high alcohol tolerance make it a go-to for big beers.

A beautiful strain for stout, porter, brown, and amber ales. Darkness produces a unique character that matches up perfectly with roasted and caramel malts. This strain is alcohol tolerant, so don’t hesitate to throw high gravity worts its way.
