In late 2020, New Riff went on a release spree with 3 new products in quick succession featuring experimental mashbills. There were the Maltster Wheat and Maltster Rye, experimenting with wheat / rye plus corn, and then this Winter Whiskey. New Riff Winter Whiskey (also a bourbon) is a 4-5 year old bottled in bond bourbon that uses oats and barley (and no rye or wheat) to create a bourbon that highlights the team’s prior experience as brewers. I don’t know much about New Riff’s history or the people behind it, but I’m definitely interested with the experimental mashbill that uses oats and barley malt in ways that few have likely ever tested for bourbon. Let’s find out if this grain experiment was a success in this New Riff Winter Whiskey review.
