Morning light strikes the brick of Louisville’s Whiskey Row and the city exhales the scent of toasted oak. You meet at the Mint Julep Hub, step into an air-conditioned van and head out through bluegrass country where cornfields and limestone soils feed the grain that makes bourbon sing. Over the next nine-plus hours you move between three very different distilleries — historic Buffalo Trace, the bold heat of Bulleit’s operation, and Rabbit Hole’s modern, design-forward facility — sampling small pours, hearing mash-house stories, and watching charred barrels breathe amber color into spirit.
