I'm a fan of Port finished Malts, and even fully matured in Port. For simplicity, I consider Port within the Sherry Cask classification, like Madeira, Marsala, etc.
I like the Balvenie 21 Portwood a lot, It is actually
@Jeff 's favorite scotch. My only gripe with it is that it's 40% abv. If it was at least 46/48%, but specially if it was Cask Strength, it would be phenomenal!
I'm currently (not right at this minute lol) working hard on a bottle of Limited Edition Ledaig 13 Port matured, LOL! Great bottle btw!
