Working on a yeast starter tonight and was thinking......can I use yeast nutrient in the wort of my primary brew? The LHBS that I got my supplies for "yeast starting" gave me a bottle of yeast nutrient and I have only used an eighth of a tsp for each stage. Did a search on this and didn't come up with much. Just wondering if there would be any advantage to add yeast nutrient near the end of the boil.
