I’m not really sherry cask lover myself but have enjoyed Palo Cortado finishes when I’ve had them, particularly the Arran one. That 7yo could be very interesting.
Whiskybroker released an 16yo Arran PC a couple of years ago that was pretty good. I’ve got a Benriach and Caol Ila released by James Eadie and the OB 20yo Bunna PC but it’s seemingly not very prevalent.
