White Labs WLP051 California Ale V
From Northern California, this strain is fruitier than WLP001 and slightly more flocculent. Attenuation is lower, resulting in fuller-bodied beers than WLP001.
Recent sequencing studies show that WLP051 belongs to Saccharomyces pastorianus species, the same hybrid species as most lager strains. However, this strain has been used to make ales for decades and was previously categorized as belonging to Saccharomyces cerevisiae
