Sorry, it really wasn't a question so much as posting an experience with commercial yeast nutrient. I have heard some people use it with no problem, and I have heard some not using it. Those that don't preferred a natural yeast nutrient like raisin juice.
My first batch I didn't use yeast nutrient, it turned out good. My second batch I just did, 5.5 gallons, used WYeast Liquid Yeast and put 5 tsp of nutrient in it. This thing fermented for almost 20 days Ended up at 12.35% and tastes good.
