The nose is salty and rich and slightly waxy. There's the characteristic sherry cask chocolate note which to me is always reminiscent of cheap instant chocolate pudding - you know, Angel Delight or Miracle Whip or similar. There's also just enough old cask smell or fustiness. Not too much, just enough.
The palate is sweet and rounded and chocolatey, before evolving into a snuffed out candle smoke taste. Delicious.
It's a very, very fine Port Charlotte, by far the best I've yet tasted. Good work on securing that cask, Ralfy, and can I have some more please?
Postscript: A couple of days later I was talking to Ralfy again and he told me that, according to staff from Bruichladdich who were at Glasgow's Whisky Festival, some of these private casks of Port Charlotte were actually filled with Octomore (due to a shortage of PC spirit). Which might explain the intense peat character of this dram, coming as it does from a pretty active cask.
