Very good. A twist on the Brooklyn, tossing away the french vermouth and maraschino in favor of coating your glass with scotch.
I tried this with with Rocker port-finished bourbon instead of Knob Creek. I think that particular bourbon was too sweet for the recipe, and Knob Creek would be more balanced. I think I'll try it next with a smokier Islay.
Edit: Lagavulin 8 worked better with my rocker bourbon.
