Resolute Reserve Oak Bourbon Barrel 2 Liter (Empty)The Resolute Reserve Oak Bourbon Barrels (empty) a great gift we thought this would be a great benefit to the flavor of our great Bourbon. Pour it in and let it sit and develop a better aged taste. 2 Liter is Resolute Reserves smallest barrel it will hold a 750ml bottle of liquor. It may be small but it is packed full of flavor once filled with your favorite Bourbon. In fact it is our fastest aging barrel. The 2L is kinda small so dont be mistaken.
