I made a basic (extract) Oatmeal Stout and added cocoa to the secondary. It's been a month and the s.g. is 1.019 (room temp was warm--in the mid-70's). My normal beer ending s.g. is usually around 1.012 to 1.014. It does not taste sweet, it tastes good. I'm not really concerned about exploding bottles but ending up over-carbonated. I had gotten to where I didn't even check the s.g. anymore but I ended up with one that was way way over-carbonated. I'd get about 1/3 beer and 2/3 foam. I'm thinking about cutting back on the priming sugar a little but I don't want it flat either. Any ideas?
