This year, Wild Rustic Spring offers a selection characteristic of Belgian and sour styles to pair with the new season. Historically epitomized by the beers of Europe, these yeast and bacteria strains have now been skillfully harnessed by homebrewers and brewmasters from our Private Culture Collection. Saisons, lambic styles, goses, Brett beers, and more are now world-class, world-wide. No matter the direction you take these wild rustic cultures, they will become your new tradition.

These strains are available to all retail customers for a limited time. Commercial customers are encouraged to order these strains during this quarter for shorter lead times! Find out more about which styles pair best with these strains at
