“70% bourbon barrel, 25% Calvados cask, 5% sherry cask” Lots of apple and pear notes in the beginning along with some wood spice, hay and iodine. Later notes have more malt and are char and oaky vanilla from the bourbon cask. the sherry is somewhat negligible and I barely detect it through the bourbon and Calvados. finish has notes of salted cashew, satisfying maritime peat smoke that blends well with a dryer, tannic finish. really cool dram Kilchoman has here. Would be interested to try some more Calvados forward single malts.
