The following strains are grown to order and are available to commercial breweries at any time of the year. Please check our yeast for homebrewer’s page for a list of strains available in homebrew pitches.

*These strains have been identified using polymerase chain reaction (PCR) to contain the glucoamylase gene (STA1), which can be an indicator of S. cerevisiae var. diastaticus. As such, these strains have the ability to utilize some dextrins which are unfermentable to most species of S. cerevisiae, and thus achieve very high levels of attenuation. However, these strains are not considered contaminants and will not over attenuate finished beer when high levels of attenuation is expected.
