A well-known, bottom-fermenting ale yeast strain, this is a yeast to be selected for its fast fermentation characteristics and its ability to form a compact sediment at the end of the fermentation process, helping beer clarity. For the production of a wide range of ales. Whitbread strain. British Ale Yeast with very mild mineral and fruit undertones. Malt balanced with good attenuation and excellent sedimentation properties. An ideal yeast for cask or bottle conditioned ales since it settles so completely. 11.5 grams. Sufficient for 5 gallons.
