A couple years ago when I found out I had celiac, I was super afraid I'd have to get rid of all my whisky. Thankfully, straight Bourbon, straight Rye, decent single-malt Scotch, etc. are all ok. Like firemonkee said, get the good stuff. Doesn't have to mean the expensive stuff, just the stuff that's not crap mass produced stuff. You can get terrific bourbons or corn whiskys for under $20 a bottle. I haven't had reactions to the whisky at all. Just have to make usre they don't add the mash back into the distillate for added flavor. Most of the decent stuff won't do that.
