So I brewed my first batch of beer a few weeks ago. It is a traditional bitter that I brewed from a pre-hopped extract that has been bottle conditioning for just under two weeks and I tried one the other day to see how it was coming along. Much to my dismay it was very flat. There was a little carbonation but still very flat tasting. Any suggestion as to how to fix it or what I did wrong. I have an imperial IPA in primary right now and dont want to screw it up! Thanks!
