I didn't eat any cheese. I have made cider before and it was pretty good - was thinking about doing another batch.
Yeah, that does sound like it, but I've never gotten this sensation from anything I've eaten before. (Other than the last time it happened, when I made Stout, obviously..)
I do have an intolerance to something they use as a preservative or flavour in Canada - I think it's Banana Pepper extract. I never came across those until I moved here, but then I got some on something once and had stomach cramps and diarrhea soon after.
I also notice that I sometimes get the same effect from some processed sauces and condiments over here, but I seem to have built up a tolerance as it hasn't happened in a long time.
I know I'm not allergic to Corn as I really enjoy corn on the cob and have never had a bad reaction to it.
It's funny you mention Dextrose though, as I used it as my gassing sugar in this batch - I was using regular white sugar before - and I used Spraymalt as my fermenting sugar this time, when last time I used liquid glucose.
Maybe that has something to do with it. Hmm. Maybe I should binge on Malt and see what happens.
