Anyone else have this happen to them? A few months ago I was having a Sam Adams (I think a seasonal) from a bottle and my face and neck got red and itchy. Started coughing a bunch. Runny eyes, the whole deal. Then about a month later I had a Guinness draught in the bottle and same thing! I used to have Guiness all the time with no issue. I basically chalked it up to macro beers or a bottle conditioning process or something. Then today a coworker brought me a homebrew Black IPA and it happened again. I've had all his other beers and this was not an issue. I'm stumped. Could it be a certain barley? Or yeast? Super weird. Any insight is appreciated.
