@Ctrexman this is for you. Finally got around to grabbing a bottle of this to compare with my recent review of Proper 12. Did a side by side. Off the bat, I can say this is practically an amplified version of the Prop. Nose was substantially more potent on the Jameson which was nice. It contained plenty of the bourbon barreling influence along with grains and fruit of some kind. The taste was fuller and somewhat smoother as well. The slight ethanol I got from the Prop was more or less absent here. I didn't really get loads of char I was expecting which was dictated on the label. Some yes. Instead it was more along the lines of burnt sugar/caramel. Vanilla as well. The mouthfeel had a pleasant oily texture. Came off a touch sweeter. The 12 had a smidge drier/bitter finish.
All in all it was an improvement to the Prop, but not miles apart. The extra $10 I paid for the Jameson compared to the Prop went towards the raised sensory intensity for me. I'd still give the P12 a whirl considering its price. Also for poops and chuckles as well. But to answer your question the Black Barrel definitely won out. I honestly enjoyed it a bit more. I'm looking forward to the next pour. Cheers my friend. 🥃
