This has a nice nose with some banana, peanut and caramel; it's sort of Snickers like. The palate is sweet with caramel and Butterfingers notes. It takes on some complexity with oak and tannic notes toward the end. The finish is the best part with a nice balance of the palate's sweetness and tannins. Water gives it more sweetness up front but also extends the tannic notes toward the end. It's a bit hot taken neat so I would recommend a drop or two of water, which doesn't compromise the flavor.
This is pretty good; it reminds me of some of the better Booker's I've had, back when they were better. It didn't bowl me over, but I'm not generally a fan of the standard Beam juice, so I wouldn't expect it to. It was definitely above average, and if you are a big Beam fan, you'll probably love it.
