Sulphites, maybe? They are often added to grapes and wines and many people are sensitive to them. They are also added to dried fruits and some other beverages, among other things. Sulphites are listed as a priority allergen in Canada.
I don't know much else about sulphite allergy or sensitivity though, other than it is treated like a food allergy with total avoidance. Just thought I would point it out.
