Served neat in a rocks glass at the bar from a bottle that was 80% empty, so I suspect it had time to soften in the bottle. Reminds me of a sweet rum syrup with a hint of black tea and a subtly hot spice character on the back end. Great length of finish with a low burn. Perfect balance with a recognizable Booker's flavor profile. Similar to 2018-4 "Kitchen Sink" Expectedly excellent
