Wyeast Laboratories, Inc. has been a leader in liquid yeast and fermentation science since 1985, offering high-quality yeast strains and specialized nutrients for homebrewers and winemakers. Based in Odell, Oregon, near Mount Hood—traditionally known as Wy'east—the company is known for its commitment to innovation, consistency, and premium fermentation products.
Our Wyeast Yeast & Nutrients collection includes an extensive selection of liquid beer and wine yeasts, covering styles from clean American ales and lagers to complex Belgian and wild fermentations. Wyeast’s Smack Pack™ system provides fresh, viable yeast by activating the culture before pitching, ensuring strong and healthy fermentations.
In addition to their world-class yeast strains, Wyeast offers fermentation nutrients designed to improve yeast health, efficiency, and stress resistance. Their Beer Nutrient Blend enhances yeast performance in high-gravity worts, while Wine Yeast Nutrient Blend provides essential micronutrients for a healthy and complete fermentation in fruit-based fermentations.
All Wyeast products are stored under strict temperature control to maintain peak viability. We recommend shipping liquid yeast with ice packs to minimize temperature fluctuations during transit.
