In Kentucky, where bourbon is to the state what wine is to Northern California, the spirit has shed its grandpa’s-drink image and evolved into a legit tourism draw, as well as a signature ingredient in treats like Cellar Door Chocolates’ to-die-for bourbon balls in Louisville and Crank & Boom’s bourbon and honey ice cream in Lexington. Bourbon trails keep on growing, and distilleries are in an arms race to soup up their facilities and tour offerings. Suffice to say bourbonism is booming.
