Why does wine give me headaches; sulfites, right?
False. Sulfites cause very severe allergic reactions in a small number of people, which is why there is a warning on the bottle, but sulfites do not cause headaches. Sulfites, which have antioxidant and antibacterial properties, naturally occur in all wine. White wines often have more sulfites than red because the tannins and flavonoids help to preserve red wines
The likely cause of wine headaches are the histamines. Red wines have more histamines because they exist in the skins of the grapes and red wines spend more time with the skins macerating to extract the pigments, tannins and flavors. Customers can try taking an antihistamine before drinking red wine. Another reason for a headache might be dehydration. Recommend drinking water alongside wine to curb those headaches.
