White Labs · Klassic Ale WLP033

White Labs' Klassic Ale (WLP033) is a liquid ale yeast designed for classic ales, such as English Pale Ale, Bitter, and ESB. This yeast strain has great attenuation of 70%, meaning that it can produce high alcohol beers with little residual sweetness. It also has medium flocculation which will result in a clear beer with good body. Alcohol tolerance is also listed as medium, so it should be able to tolerate up to 6-7% ABV depending on the recipe. For best results the ideal fermentation temperature should be kept between 19.0-21.0 °C.
