Backbone Bourbon Uncut is a bourbon bottled at full proof, so it is likely to show a bold, concentrated style. For a new whisky drinker, that usually means bigger flavour, more intensity, and a warmer feel than a lower-proof bourbon.
As a bourbon, it is broadly associated with a sweet-and-spice profile built around oak influence and the grain character of corn. Expect a robust, full-bodied experience that may open up with a little water.
