What is proprietary yeast?

Proprietary yeast refers to yeast strains developed and owned by specific companies or organizations. These strains are not publicly available and are used for various purposes, including brewing, fermentation, and winemaking. Proprietary yeast strains are typically created through genetic engineering or selective breeding to achieve desired characteristics, such as improved fermentation performance, flavor profiles, or tolerance to specific conditions. Using proprietary yeast can provide several advantages, including process efficiency, consistency, and a competitive edge in the production of fermented beverages and foods.
