In order for yeast to perform fermentation properly they need certain substances in a form which is readily available to them. Most homemade wine ingredients do not contain enough of these so to get a good fermentation we need to add yeast nutrient.
Yeast nutrient contains ammonium sulphate and ammonium phosphate.
