Wine turns my guts into a jet propulsion laboratory.
Tremendous farts. (True! Not trolling.)
If I'm at a party or something and I feel one coming on, my impulse is to rush to the bathroom to release the monster, in case it drags a "cortege" along with it... (because once in a blue moon it does!)
I know some people develop blotchy skin or patches of red shortly after consuming wine.
Their skin returns to normal in a few days.
