Had my eye on this one for a while. Went on sale for $22 so I pounced. Poured neat,nice thick legs. Nose has sugar daddy, black cherry, cinnamon and rye spice. Very little wood and even at 100pr almost no ethanol. Heavy mouthfeel brings a blast of caramel, cinnamon and spice transitioning to oak. Very robust with strong heat(not burn though) Finishes medium long with drying oak and cinnamon with warming sensation all the way down. This bourbon is deep and rich and swings a heavy bat, huge improvement over regular 86pr. I think it represents superb execution of a standard bourbon profile. Its sweet but not too so, oak dryness but not bitter. It has plenty of heat but is not harsh. Most palates will deviate to individual preferences but OF Sig is kinda like the baseline imo, only cranked up several notches. There are others that I prefer for sure but at this price point it is solid. 84/100- would purchase again
