* Strains with (STA1+) at the end of the name have been genetically typed in the White Labs lab using polymerase chain reaction (PCR). Through this genetic testing, White Labs has determined the strain contains the STA1 gene (glucoamylase), a potential indicator of Saccharomyces cerevisiae var. diastaticus. The strains White Labs carries with known Saccharomyces cerevisiae var. diastaticus genetics have been researched and validated to perform without excessive over-attenuating.

** WLP1983 is one strain, but it can ferment at both ale and lager temperatures. The first set of values is for fermenting ales, the second set is for fermenting lagers.
