Zinc Sulphate Heptahydrate (ZnSO₄ x 7H₂O) – 250g
Zinc is the “bare essential” yeast nutrient. In an all-malt beer, made with high quality malt, a brewer should need nothing else for yeast nutrition. Zinc Sulphate Heptahydrate is a simple and effective way to give yeast the nutrient it needs without increasing the amino nitrogen content of wort.
Suggested Usage Rate: 0 .5 to 1 g / 10 HL
Application: mix Zinc Sulphate Heptahydrate with 250-500mL water and add to fermenting vessel just prior to pitching yeast.
