I'm on my 2nd brew tonight. First time using a 5-gallon kit. After putting in the fermenter, I noticed there is only 3.8 gallons. I started out boiling 5. I knew I would lose some in the boil due to steam... and some (about a quart) when putting into the fermenter and stopping short to keep the junk out. But 1.2 gallons short?? Is that normal? Should I go ahead and bring it up to the 5-gallon mark? I like medium-strong beer... but this seems like it may end up being too strong for my taste.
