Tennessee whiskey was an Earth alcoholic beverage, a whiskey originating from Tennessee in the United States of America. Dr. Leonard McCoy noted Tennessee whiskey to be the "secret ingredient" to the McCoy family recipe for southern baked beans. After introducing Spock to the beverage, he later shared the bottle with Kirk, and the two drank it while performing a sing-along of Row, Row, Row Your Boat. (Star Trek V: The Final Frontier)
