With a mashbill comprising 51% rye, 44% corn and 5% malted barley, Standard Proof Coffee Rye is made using whiskey sourced from an undisclosed distillery in Tennessee. It is then aged for two years in new American oak barrels, infused with Arabica coffee for 12 weeks and bottled at Standard Proof Whiskey Co. in Nashville. This expression was previously called "Red Eye Rye."
