I forgot to mention Glenfarclas 15-17-21, and I agree completely!
ETA: The Glenfarclas 40 is an older expression that is outstanding. Usually 40 year old whisky is grossly over rated, and not worth your time or money. This is worth seeking out.
The 40yo version sold at the distillery is the least expensive expression of this, and it is fantastic. But you don't need to break the bank to buy super expensive whiskies like this to get a great dram. Trust me--I know. I collect and have tons of collectible whiskies, but I usually drink the younger (and more often now than not, peatier) expressions.
