Bourbon is a corn-based, aged spirit that, while legally can be produced anywhere in the U.S., is Kentucky’s signature liquor; in fact, Kentucky distilleries make 95% of the world’s bourbon and the Bluegrass State hosts over a million visitors annually for bourbon tasting tourism. Because of the liquor’s aging process variation, bourbon’s colors range from light amber to dark caramel and each bottle must contain at least 40% ABV. Bourbon can only be called bourbon if it’s aged in an oak barrel; barrels must be new and are pre-charred to help the liquid extract as much flavor as possible from the wood.
