The nose is full of sweet, floral notes. It's like a rose garden. The palate is also very floral and perfumy. There is a very light character to it. The port is most evident in the late palate into the finish, where it really shows, so much so that the finish recalls port finished Scotch.
Decent though not particularly complex. I should disclose that light and floral is not, generally, my favorite flavor profile.
N: Semi-strong alcohol upfront with plenty of wine. Somewhat dry, with a little bit of pepper and medium wood.
P: Rich and coating, with some warmth. Definite wine, berries and fruit, some wood over time. Light pepper.
F: Warming initially but then it settles down. This is where the bourbon presents most strongly - the black cherry, earthy notes, a hint of vanilla. There's some port hanging on as well as some slightly dry wood, but it doesn't go bitter. Lightly dusted with cinnamon.
The port is all over it with sweetness and a rich wine note, but it doesn't have a grapey thing happening like some wine-finished bourbons can (Woodford Sonoma). To be honest, there are elements that remind me of a good midlevel sherried scotch.
I feel like this is what you'd get if Balvenie set out to make a bourbon.
