Okay, I just got back from the homebrew store and forgot to buy my nutrients. However, I was considering using dried currants (very similar to raisins, just smaller and less juicy) which, I understand may allow me to skip the nutrients. If I were to do this, how many oz. would I need for a 1 gallon and/or a 3 gallon batch? I assume it would be the same as if I were to use raisins.
