Wine Yeast Nutrient by Mangrove Jack's.
A diammonium phosphate-based yeast nutrient complex that supports yeast health to improve fermentation of wine from grape or other fruit juice.
Yeast nutrients help to provide an optimal environment for yeast to thrive in, leading to an all-around happier, healthier, and faster fermentation. The use of yeast nutrients can improve the overall flavour, aroma, and quality of the final product, helping you to produce consistent wine every time.
This is a 23.5g (0.83oz) sachet of Wine Yeast Nutrient suitable for treating 15-23 litres (4-6 US gallons) of wine must.
Directions:
Add sachet contents to juice must and stir well to dissolve, then pitch your yeast and ferment according to instructions on yeast packaging.
Please note that Wine Yeast Nutrient is designed to help wine yeast work more effectively. It does not contain wine yeast which is available separately.
