I’ve spent hours looking for the answer to this question, with no luck. It seems like the kind of question someone must have asked before, and I think that someone here will know (or link me to) the answer.
Here’s the question: Why is it that I am more likely to get a headache from drinking bottled beer than draught?
First of all, I’m not talking about hangovers, per se. I’m saying that I can drink one or two pints of draught (occasionally I’ll even have a third), and feel fine. But - often when I have one or two 12-oz. bottles of beer, within an hour or so I’ll get a splitting headache.
Second point of clarification: I don’t drink “macrobrews”. I’m talking about microbrews, and my preference tends toward amber ales - medium hoppiness. But it doesn’t happen with just one type, and it can even happen with the same beer (the bottled version giving me a headache when the draught version doesn’t, I mean).
Is there something (like the pasteurization, or addition of preservatives) that happens in the bottling process that is causing this?
