Biotin Yeast Nutrient, 2oz
Biotin (Vitamin B7) is an essential cofactor that supports yeast metabolism and healthy fermentation. It plays a key role in fatty acid synthesis, amino acid metabolism, and energy production—processes that directly impact yeast vitality, alcohol tolerance, and fermentation completeness.
Most malt-based worts naturally contain biotin, but grape must, honey, or sugar-based fermentations (like cider, mead, or hard seltzer) are often deficient. In these nutrient-poor environments, yeast can struggle to reproduce and may produce higher levels of unwanted byproducts such as hydrogen sulfide or volatile acidity.
Supplementing with biotin ensures robust yeast growth, faster fermentation starts, and cleaner flavor profiles.
- Wine & Mead: Add at yeast rehydration or early fermentation.
- Cider & Hard Seltzer: Add with your complete yeast nutrient blend.
- Beer: Useful for high-adjunct or sugar-heavy recipes.
Use 0.1–0.5 mg per 5 gallons (19 L), or according to your nutrient formulation.
- Promotes strong yeast growth and vitality
- Supports complete attenuation
- Reduces the risk of sluggish or stuck fermentations
- Enhances fermentation consistency in low-nutrient media
