Well it's been a while since I've brewed anything (Scottish light ale in the primary now though!!!). But a few years ago one of my batches was an IPA. It was very tasty and I was pretty proud of myself. However, if I drank it, I immediately got a killer headache. I managed to find something online about hop allergies. At the time I was on a big IPA kick and nothing else bothered me. Maybe it was the fact that it was a home brewed IPA? I don't think it was any sort of infection (looked and tasted great). Kinda has me afraid to brew an IPA now that I'm starting to brew again. Anyone else had this problem?
