Are there any bourbons that are 100% corn?
Call me crazy, but let's suppose you had a few whiskeys that were each 100% of one of the major mash grains (Corn, Wheat, Rye, Barley, etc.). After they have been similiarly aged, could you mix them to simulate different mash bills?
By the way, does anyone have a consolidated list of mash bills of many bourbons? I know that distillers don't like to share this information, but I've seen it in a lot of posts.
