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.
The 'low wines' spirit safe. This ornate equipment is traditional in the whiskey industry. The distiller can open this box to take a sample of the spirit coming off the still to check for quality. Notice the turkey engraved into the glass and the lion's head on the latch.
Wild Turkey uses a three day fermentation. This batch is nearing the end of the fermentation cycle. The grain cap is thick and chunky. As the fermentation completes this cap will break up and sink.
