Just finished up #4. Nose has notes of leather and fruit, I can tell a higher proof than the others. The pallet is bright with a small sip coating my mouth, but the proof while not overwhelming makes it a little hard to make out any particular flavors but it still feels in the fruit spectrum. The finish is where some cinnamon starts to come through, it's not super long but it's there for a few seconds. I added a little splash of distilled water to see what would happen, and the cinnamon has come from a note on the finish to a red-hot-esque note on the pallet. I gave it another splash but it didn't enhance anything, so I stopped there.
My guess - Booker's...
...is where I should have stopped
But stupid me guessed "Any Booker's release other than Country Ham"
