Wild Yeasts & Bacteria

Wild yeasts and bacteria bring complexity, funk, and acidity to brewing, allowing homebrewers to craft unique sour, funky, and mixed-fermentation beers. Traditionally used in styles like Lambic, Berliner Weisse, Gose, and American Wild Ales, these organisms contribute flavors ranging from fruity and tart to earthy and barnyard-like.

Our Wild Yeasts & Bacteria collection includes a variety of Brettanomyces, Lactobacillus, Pediococcus, and mixed cultures from industry-leading brands like White Labs, Wyeast, and Omega Yeast. Brettanomyces is known for its distinct funk and tropical fruit notes, while Lactobacillus and Pediococcus produce lactic acid for controlled souring. Mixed cultures provide a combination of wild yeast and bacteria, creating layered flavors that develop over time.

These wild fermenting organisms can be used for primary fermentation, secondary aging, or blending, depending on the desired intensity of funk and acidity. Whether you're looking to experiment with a 100% Brett fermentation, add a tart kick to a kettle sour, or craft a barrel-aged mixed-culture masterpiece, this collection offers everything needed for creative and expressive fermentation.
