BrewNutri-AZ is a complete and balanced yeast nutrient from yeast autolysate. It is a high-nitrogen supplement rich in amino acids, minerals (such as zinc), and vitamins designed to promote robust yeast growth and health.
This product is specifically engineered to address nutritional deficiencies in challenging brewing environments, such as high-gravity wort with high adjuncts. It provides yeast with essential organic nitrogen, free amino acids, and peptides for effective supplementation, resulting in more consistent and stable fermentations.
Key Benefits & Applications
Prevents Sluggish Fermentations: Supplies yeast-accessible nitrogen and micronutrients to maintain healthy yeast metabolism and prevent stuck or slow fermentations.
Enhances Stress Tolerance: The inclusion of zinc and other micronutrients helps improve yeast metabolism and resilience, particularly in nutrient-limited or high-stress conditions.
Improves Yeast Re-pitching: Significantly improves the yeast's re-inoculation (re-pitch) ability, helping to maintain strong yeast condition across serial repitchings.
Reduces Off-Flavors: By ensuring a robust fermentation, it helps reduce the production of off-flavors, leading to a cleaner and higher-quality finished product.
Promotes Batch-to-Batch Consistency: Supports reliable attenuation and a clean finish, ensuring more uniform results across different production runs.
Practical Application Effects
When applied to yeast propagation, BrewNutri-AZ can markedly increase the viable cell count, as well as raise the wet weight of yeast during propagation.
BrewNutri-AZ: 0.3g/L
Original gravity: 12°P
Initial yeast pitching rate: 3×106CFU/mL

After 24 hours of fermentation, the yeast wet weight was measured. The blank group was 49 g/L, and the experimental group reached 57 g/L.
When applied to re-pitching yeast, BrewNutri-AZ can significantly improve its fermentation efficiency.
BrewNutri-AZ: 0、0.225g/L
Original gravity: 12°P
Initial yeast pitching rate: 1×107CFU/mL
In the figure, G represents the number of yeast recovery cycles.






Yeast status determines brewing quality, and scientific nutrient management is the key to unlocking the full potential of yeast. Proper application of Angel BrewNutri-AZ helps optimize nutrient supply, which not only improves propagation quality and increases viable cell count, but also effectively slows down activity decline of serially repitched yeast and stabilizes the apparent degree of fermentation as well as the overall fermentation process. Empowering yeast with targeted nutrition enables high efficiency, stable production, and cost reduction in every production run, laying a solid foundation for consistent quality in beer brewing.
