Red wine headache. Red wine headache (RWH) is a headache often accompanied by nausea and flushing that occurs in many people after drinking even a single glass of red wine. This syndrome can sometimes develop within 15 minutes of consumption of the wine. The condition does not occur after consumption of white wine or other alcoholic beverages. Some individuals report that they get a migraine headache hours later from drinking some red wines. No one knows for certain why this syndrome occurs. It probably has more than one cause.
My suggestion is the more tannins the wine has, [the] more migraine attacks it triggers, says researcher Abouch V. Krymchantowski, MD, PhD, of the Rio Headache Center in Rio de Janeiro, Brazil, in an email to WebMD. Tannins are flavonoids in red wine that give it a drying, sometimes puckering quality. The more tannins a wine has, the more it will dry out your mouth after you sip it. No one is quite sure why red wine may trigger headaches, but some studies have shown that tannins may boost production of the brain chemical serotonin.
