All wines has sulfites. The occur naturally. They're also extremely over used in some wines. Lots of people blame them for headaches, but I think they are more the poster child and get blamed because it's what people know. High sulfite wine has a ton of other additives as well and any of those 73 ingredients that don't have to be listed on a imwine label could be giving you a headache

That's interesting! Generally one glass of red and I'm hurting. Crazy that they don't have to list it on the label.
