Bone Snapper X-Ray Rye Whisky 4 Year Reserve (Batch #4) is a 110 proof, 750 ml bottle of rye whisky aged for four years in charred oak barrels. It is made from a mash bill of 95% rye and 5% malted barley. The whisky is bottled at a higher proof than most rye whiskies, giving it a bold and spicy flavor. The whisky has notes of caramel, vanilla, and baking spices, with a long, smooth finish. It is a great choice for sipping neat or in cocktails.
