OK - bought this a while ago and I've been letting it open up after a disappointing first few tastes. Poured about 1/3 of an oz about 15 minutes ago, so lets see. Nose - I'm getting a pretty standard "middle age" so under 12 if not under 10, but over 6 years old nose. I know this is a blend of aged bourbons ,but I can't recall so if I'm off I'm off. Vanilla, caramel, touch of dry lightly toasted oak, and perhaps some light fruity esters. I'm assuming those esters are partially influenced by the rum, but I could see getting these notes on a standard wheated bourbon as well. I'm not getting much in the realm of darker notes, even the oak is light and toasty. Taste - sweat, creamy corn, vanilla, wood spice, pie crust, and some notes of fruits. I think there's a bit of a jam, but I can't place it. It's sweat, younger wood character, spicy wood, and a bit hot. Finish - spicy, a touch hot, lightly toasted oak, and that's about it. Cuts off outside of just a lingering heat. Oh, I spoke to soon, I'm getting a touch of nutty notes now at the finish. This is a nice bourbon and it gives me a bit different and out of my normal bourbon notes, just due to more spice, lighter notes, and a lack of deeper darker notes I'd expect on a whisky with some age. The rum casks didn't really stand out, I think they are playing a role in this, but I'm not getting any notes I can clearly state are the result of the secondary finishing. I'm looking forward to how this develops in another 6 months of being open. With the above said, this is a nice 40-50 dollar bourbon, the 100+ price tag in most markets really drives the enjoyment and it is going to get reflected in the score a hair. I was a 2.25 without price and I tend to not overly let myself shift scores due to price. The idea is always 3 is worth getting if you're into the style and the price is your comfort zone and it adjusts from up or down accordingly. I however do also feel there are certain notes and flavors that should or can come with these higher prices and this bourbon drinks like a younger and yes less expensive bottle and so I'm dropping it to a 2. Wow that nutty note at the end really came out of nowhere. Without that I might have dropped into the 1's but it really made this an enjoyable pour.
