I have not had red wine in almost two months, and had about 5 ounces in a half hour period. That was four+ hours ago, and my face and body are still slightly itchy, but particularly my face. I read while researching it here that red wine has histamines. Could it be that I am now more sensitive to the histamines that did not previously bother me? (I have never been a "regular" wine drinker, maybe once every two months, occasionally more used just in cooking.)
