Wyeast

What Wyeast does

Wyeast Laboratories, Inc. is a family-owned manufacturer of premium liquid yeast strains and fermentation cultures founded in 1986 by Jenny Kreft in Hood River, Oregon. Its core offering is the Classic Culture Collection of over 100 characterized and quality-tested yeast and bacteria strains spanning beer, cider, wild & sour, wine, mead, spirits, and saké categories, packaged primarily through its proprietary Activator Smack-Pack System — a trademarked packaging architecture that delivers a minimum of 100 billion viable cells per pack and provides an in-package viability test through nutrient-induced swelling. The company also operates a Private Culture Collection of seasonal limited-release strains on a quarterly cadence.

Revenue is generated through two channels. Home enthusiasts purchase Wyeast products indirectly through a global network of 60+ online retailers and dozens of brick-and-mortar homebrew shops across 14+ countries. Professional breweries, wineries, cideries, meaderies, distilleries, and saké breweries order directly via an account-based quote request system, accessing the full catalog plus proprietary strain banking services (dual-format culture storage at -70°C and slant overlay) and technical support covering strain selection, pitch rates, propagation, and fermentation optimization. Wyeast does not publicly disclose pricing.

Operationally, Wyeast employs approximately 40 people at its expanded Hood River facility (built out in 2021), partners with named craft breweries including Upland Brewing Company and Reuben's Brews via its Core Brewer Spotlight program, and continues to release new seasonal strains through 2026 with no outside institutional investment or ownership change disclosed across 39 years of operation.
