Can somebody help me out with the proper technique for using yeast nutrients. I picked some up at the LHBS when I bought my ingredients for my next batch as it will have a higher O.G. that what I have brewed in the past. A few posts I have read suggested that adding it in to a high gravity beer was a good idea and the guy at the store agreed with this. It was't until I got home that I realized I have no idea how to use the stuff. Does it get added before, after or at the same time as the yeast? Does it need to be added to the boil? Does it go in dry, or in a slurry of some sort? I tried surching for an answer, but all the posts I found just seem to say, "add yeast nutrient". As I said no clue, so any tips or tricks you could offer would be greatly appreciated. The nutients I bought are called yeastex if that makes a difference. Thanks in advance for your help.
