The nose is peaty, but with some floral notes, and also some vanilla.  Like the better peated whiskies,  this nose suggests that there is more than just smoke to come.  The taste is peat led and phenolic, and the 21 years in cask also shows up with lots of oak spice, without being woody.  There are some sweet treats hidden in the taste like barley sugar and fruit.  Nice, dry finish with tingle of peat and the alcohol can be detected at 46% ABV. No balance issues, but not sure what this trying to be... a big peat monster or a spicy, fruity speyside with a peat back note.  Seems to fall somewhere between the two and doesn't quite do it for me. I prefered the peated 10 year old expression because I got more of the fruity spirit and less peat and oak.
