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. Attenuation: 63-70% Flocculation: Very High Optimum Ferment Temp: 65-68°F (18-20°C) Alcohol Tolerance: Medium
White Labs has moved to new packaging - PurePitch® Next Generation - which contains a larger pitch and new re-closable pouch. White Labs provides a lot more information about the new packaging and pitch rates on their website.
Why PurePitch Next Gen versus other options?
Scan the barcode on the back of each package to be taken to their online calculator. Enter the volume, strength, and pitching temperature of the wort you are fermenting and the calculator tells you exactly how much yeast to pitch. You will be fermenting like a professional brewer, using the same concentration of yeast every time and enjoying more consistent results. Don't need a full package? Put the lid back on and store in the refrigerator for your next batch. White Labs has also increased the viability (the number of living cells in the package) over the shelf life of the yeast. Next Gen strains are grown in their unique, small-batch reactors to assure freshness and then packaged in a special film that allows for off-gassing, assuring that their viability is absolutely industry leading.
