Wild & Sour Overview

For those who love to ferment on the funky side, we have a variety of cultures for making wild & sour styles. They provide fermentation or souring to achieve distinctively complex taste, aroma and mouthfeel.

Why Use Wyeast?

For over three decades we’ve been a leader in producing premium fermentation products. Our liquid yeast and bacteria strains are recognized around the world, and we’ve partnered with some of the most successful craft beverage brands around. But we’ve never stopped exploring new ways to ensure that every product that leaves our Hood River facility is of the highest quality possible.
