Yellowstone is another old bourbon brand. The most recent iteration of the Yellowstone distillery, owned by Glenmore, closed in 1991, with some of the bourbon after that time being made at the Medley, distillery, now also closed. Eventually, the label was sold off to the Luxco Company, the independent bottler that also bottles the current incarnation of Rebel Yell. Chuck Cowdery has a brief two part history of the brand on his blog.
The bottle I'm trying today appears to date from 1979, so it's from the Glenmore era.
Yellowstone Bourbon, 86 Proof (43% abv), 200 ml bottle.
The nose on this has a lot of fruit candy. I'm talking Juicy Fruit gum (or maybe it's Fruit Stripe gum), also some Kraft caramel cubes and vanilla, very nice stuff. The palate also has a lot of candy notes, but now I'm getting salt water taffy, more caramel, and English Toffee ice cream. The finish has toffee. Despite all of the candy flavors, this isn't cloyingly sweet and has a richness of body that makes it quite pleasant and drinkable, if not overly complex.
