High Noon Ingredients/Allergies?

I finally tried these and they're pretty good. The downside? Difficulty breathing and crazy itchy hives.

Does anyone know what's actually in these? I tried searching around and only found the nutritional info. I know they claim it's just sparkling water, vodka, and juice, but there's got to be something else to cause a reaction like this. I even experimented with all the ingredients both separately and together when I mixed my own drinks.

I don't have this issue with white claws, truly or any other hard seltzer brand I've tried. Any ideas?
