I have no doubt that it is a serious problem. The point I was trying to convey is that simply shopping by grain mix is likely a very hit and miss system because the distillation will not reduce residual glutens carried over from the mash and this can occur simply from the yeast. The only definitive way to tell is try it, and that is likely not a desireable method.
Even though I am from KY, my preferences run to Scothc, Irish and Bourbon in that order, with gin and wine close seconds. Unhappily I have found that he heart medicine I now take is not compatible with any of them and it is the alcohol that is the culprit. Sadly we sometimesmhae to play the cards we are dealt. Luckily in my case, the problem is the alcohol which does cook away, so I can at least do some creative cooking to enjoy.
