Sulphites in home brew? Any brew chemists out there?

Ok - accepted it can't be hops, which is good.

I still think histamines or other amines.

According to my allergist histamine containing and histamine releasing foods can be a problem. Some foods ferment in your guts and give off chemicals which could be a problem.

Gluten - probably not as i'd react to all beers which I don't.

I had a bottle of stout the other week from a batch that did not affect me two months ago, but this bottle did. I'm wondering if beers give of increasing amounts of amines as they age. Maybe the 150 lashes I had was old?

I majored in microbiology and immunology, studied oenology before that. Seems likely to me that you're sensitive to the biogenic amines from yeast and bacteria. Different strains of yeast will produce these in different amounts under different environments, so maybe that's why you react to certain beers but not others. Explains why you can't touch anything from the deli counter too!

And as far as I know (which isn't too much!) I don't think amine levels would increase in a microbially stable drink during ageing. Bottle conditioned homebrew however - maybe... Hey, you could go full circle and and sulphites to your homebrew and force carb instead
