New Riff Single Barrel Bourbon is made with the same mash bill as the brand's standard bourbon release: 65% corn, 30% rye, and 5% malted barley. These single barrel releases are selected by retailers or on-premise locations. Each single barrel bottling is aged for 4 years in 53-gallon new, charred American oak barrels. Additionally, they are bottled at barrel proof without chill-filtration so expect to see variances in both flavor and proof with each barrel.\n\n
