I have a problem with my skin which is caused by eating gluten free products. Some us coeliacs react to this.
I have also recently discovered, to my horror, that some wines are not not gf because the barrels used for storage and the cork are sealed with flour paste. Fortunately, i have found a couple of compamies that sell gf wine. However, I'm sure i saw some gluten free wine in Sainsburys but i cannot find it now
