O my first batch came out ok, it was a all malt amber kit. I just brewed my new batch which is oktoberfest all malt also. My question is do I need to put this in a 2 nd fermenter? I have a 6 gallon Carboy from my dad but not sure when to use it he passed on, or do you just use them when you are doing an all grain batch? Any help would be great. My first batch did not seem to be high abv? Any thing that might cause that? I followed the kit to the T.
