Feast for the yeast
"I have never used the yeast nutrient before and it was one of the ingredients in a recipe that I was following. Given the importance that the yeast contributes to the overall success of the beer any chance to help it will be worth its use. The cost of the Yeast Nutrient is minimal and the amount used for a batch is so small that it should last for ages. The beer that I made with the yeast nutrient turned out great. I think I will make the use of the nutrient a standard addition to future brews."
