Product Information

PLEASE NOTE: We have updated our names for easier identification, moving away from European appellations and moving more toward their actual uses. This change is only to the names; the product ID numbers and the strains themselves (along with their fermentation profiles and properties) will remain exactly the same. The names for our cider, mead, and malo lactic cultures are not affected.
