Awfully close to their red blend however it has a chalky, dusty, leathery thing going on that the red blend doesn't. They both share the same extreme sweet peppery note, and the vanilla but the 100% rye is more intense, more floral, dryer and definitely less sweet. Red blend is also much creamier and sweeter on the nose more like an Irish whiskey. At the extreme end S&B rye tastes almost like a dusty rye infused almond extract...Ya theres definitely more rye spice here. A very interesting one, and like the red blend it's so different I barely know how to score it...Considering the price I suggest trying out the red blend first and if you like the distinctly vanilla/peppery rye, you'll really enjoy this.
