So what explains my reaction? The Barefoot wine that caused my gluten intolerance reaction did have a cork but it was not plastic (came from a tree) - I had a really hard time getting it off, but most do have metal caps that screw on and off. As I said before, those seem to be fine. There have been other wines that friends have given me that also caused reactions...

Not true. I have used a variety of Barefoot wines with the screw caps and I had been fine. When I used the exact same brand with the cork, I had a really bad reaction. All Yellow Tail wines also give me bad reactions.

It depends on which Barefoot Pink Moscato you use. While I had no reaction with the screw cap, I had a terribly bad reaction with the cork of that same brand.
