Wild Turkey does not use any grain that is a genetically-modified organism (GMO). Their process is very traditional and they pay a premium for the natural grain. They are also worried about any future repercussions of using GMO's. The whiskey distilled today will not become a bottled product for another 4 to 15 years. If a GMO grain is discovered to have an issue 5 years from now, or if the government decides any GMO products must be labeled as such, then the distillery would be in quite a bind with all that aging product now affected. The premium they pay for non-GMO grain is considered insurance against any possible issues later.
