Old parchment label Glendronach 15 year old (100% Sherry) from the early 90s. For being 80pf its really good (and flavorful). It definitely has the Dronach skeleton with a strong raisin-y/stewed fruits/baking spice profile. The nose is real grape-y. A great pour if you're looking for something a little milder on the palate but still flavorful.
I don't think I've ever had a bad Dronach. How is Macallan still in business?
