Old Crow Kentucky Straight Bourbon Whiskey is sweet and light, with vanilla and caramel notes and crisp and light finish. It's aged for a full three years in new, charred white oak barrels. Old Crow Bourbon is named for the inventor of the sour mash process, Dr. James C. Crow. In fact, in 1835, Old Crow bourbon was the first bourbon to begin using this process that today has become a standard in the bourbon industry. The Original Sour Mash Bourbon! Enjoy!
