Im readin the Complete Joy of Homebrewing 3rd edition and I have a question. Im getting a homebrew quit that has two ale pails and lids on both of them along with airlocks. I assumed this was a closed system because your sealing everything up but from what I read a bucket is an open fermentation. Im kind of confused as to whats what. Any guidance would be appreciated as Im getting ready to start my first brew this week after picking everything up on Wed.
