I don't think tannin is my problem, I just read this, and I drink a LOT of tea and have never had a problem. "Tannins in tea, give the beverage its astringency. Teas with high levels of tannins have a bitter taste accompanied by strong astringency, seen especially in green and black tea. "
Also wondering about the orange juice I used with it. I did read that Tropicana pure premium orange juice was 100% gluten free, though it doesn't say that on the bottle. Other sites said it is and some said it's not gluten free.
I haven't bee tested, don't have insurance. But I think I'm more gluten intolerant than Celiac. I can eat stuff made with unbleached flour without having any issues. But I had to stop drinking all wine, it really bothers me and I assume it's because they use wheat paste to seal the barrels, even ones that say they don't, like Barefoot really bother me. So...
