Morgan's Yeast nutrient is basically food for the yeast and aids the yeast in spreading strongly when pitching. Yeast Nutrient bolsters the yeast to attain an untouched, uncontaminated fermentation, decreasing residual sugar. Can help avoid “untypical ageing off-flavour”. Helps lethargic musts and worts and results in fast and complete fermentation. Use one sachet per 20-25 L wort.
