It's hard to believe that this has never seen a sherry barrel from the nose - the port comes through sharply, but the nose is very nutty - almonds and walnuts - these must come from the bourbon barrels. The nose is quite powerful- I get red fruit, spice/char, hints of vanilla.
The port finish is very apparent- I get the sweet red port flavor up front but it is very well balanced. The whiskey is very nutty and malty and is rounded out by the port. There is wood and more port in the finish, as well as orange peel, pepper, and cloves.
This whiskey is very robust but the balance is perfect. The strength of the port does not take over the whiskey.
This is very festive - I'd recommend it any time of the year, but it's particularly suited to fall, Thanksgiving and Christmas. It'd make an excellent accompaniment to a special holiday meal, with dessert, or as dessert. Just be ready to share it ;)
