Hey guys. So, turns out one of my thermometers was out of calibration by a significant amount (8 degrees F). I held what I thought was the right temp in the mash the entire hour. The beer is a double IPA and was supposed to come out to a OG of 1090, but instead hit 1050. Being late in the day, the brewing store was already closed and I had no extra malt on hand to bump it up.
So, it's been 1.5 days now and i'm wondering if it would be possible to boil maybe a half gallon of water with ~2 lbs of DME and add it to the already fermenting vessel? I realize that to hit that 1090 i would have to do closer to 5, but don't really want to add that much. At the same time I don't want to be so low.
13 oz of hops made this a stupidly expensive brew, I'd like it to be somewhat drinkable.
