• Provides a concentrated source of bioavailable zinc to ensure healthy yeast growth and metabolic efficiency.
• Enhances the uptake of maltose and maltotriose, leading to more complete and faster fermentations.
• Promotes cleaner fermentation profiles by reducing the production of acetaldehyde, diacetyl, and sulfur compounds.
• Essential for high-gravity brewing and maintaining yeast vitality in serial repitching scenarios.
• Improves yeast flocculation and sedimentation, assisting in beer clarity and reducing filtration costs.

Angel Yeast BrewNutri-Z is a specialized, high-zinc yeast nutrient designed to target the most common nutritional deficiency in beer wort. Even in all-malt worts, zinc levels often fall below the optimal threshold (0.3–0.5 mg/L) required for robust yeast performance. BrewNutri-Z provides an inactive yeast-based source of zinc (5.5–6.5% w/w) that acts as a critical cofactor for protein synthesis and enzymatic reactions during both growth and alcohol fermentation.

By ensuring optimal zinc levels, brewers can significantly reduce fermentation lag times, improve attenuation in high-gravity environments, and protect yeast against the stresses of high alcohol and sugar concentrations. This results in a cleaner finish, better foam stability, and superior yeast condition for those looking to harvest and repitch their yeast over multiple generations.

Usage Rate
0.005–0.01 g/L (0.5–1 g/hL), adjusted based on wort composition and fermentation stress level.

Application Instructions
Dissolve in sterilized water to ensure even distribution. Add the solution to the kettle 10–15 minutes prior to the end of the boil, or dose directly into the cooled wort in the fermentation vessel.

Applications
Beer • High-Gravity Beer • Serial Repitching • Adjunct-Heavy Worts • Nutrient-Deficient Worts • Improving Flocculation.
