So I had a real "eureka!" moment tonight. The special lady is out with some coworkers having a beverage, and i'm at home with the kid. He and I were in the kitchen - was making dinner, he was drinking some milk. I finished up the pasta and sauce, and thought to myself, "I think i'll have a homebrew". I'd put two 22oz'ers in the fridge earlier, and they were pleasantly cold by this point. So i cracked one open and poured it into a pint glass. It came out really foamy.
In the past I'd just poured the beer into the glass and let it rest for a bit, then topped it off after a minute or two. Tonight I couldn't wait to taste that sweet malty nectar, so i thought: why don't i just cap this bottle with a wine bottle stopper
, shake it up and bleed off the excess C02?
Well, if you read the thread title, you probably know what came next. There was a loud bang and a geyser of beer shot up. To give you an idea of the blast radius, I have 10ft ceilings, and there was about a 3' ring of beer on the ceiling. I swung the 22 up to my mouth as fast as i could, but by that point there was nothing but a lace of foam on the inside of the bottle. I just stared at the ceiling as beer dripped down onto my face, ran down behind the stove, dribbled off the side of the refrigerator, and soaked my socks.
So I had time to think about this while cleaning up the floor, the wall, mopping the ceiling, and wiping down the fridge, and I think i may have isolated the problem.
If an brewing calculator calls for priming sugar in oz and I use another online converter to figure out oz to cups, presumably the conversion calculator is working with fluid oz, not oz by weight?
I have a sinking feeling that I know the answer.
