This expression is a blend of sherry casks (40%) and bourbon casks (60%).  The nose on this expression is great, very sweet with sherry, grapes and pear drops or ester.  The taste has tang of salt and fruity.  The finish has sherry dryness and quite peppery but still smooth and the peat smoke finally appears late in the finish.  A great expression, I think sherry casks and peated spirit go well together, and after 25 years in cask the smoke and peat notes are more subdues than the younger, more feisty expressions.
