Next Gen: Double the amount of yeast! WLP002 is a classic ESB strain from one of England's largest independent breweries. This yeast is best suited for English style ales including milds, bitters, porters, and English style stouts. This yeast will leave a beer very clear, and will leave some residual sweetness. The "Next Generation" PurePitch packaging contains 2x the amount of yeast, very near the rate recommendation that pro breweries use without the need for a starter.PurePitch® Next Generation- 2x the pitch rate: Now with more yeast, get a foolproof fermentation without a starter.
