I'm a huge fan of the peats, unlike many here including @
Adam Smith, and also enjoy the sherry cask ones.
I pretty much enjoy any peat 10 years or older, any regular/sherry oak single malt or blended malt 12 years or older... with a handful of exceptions.
I really don't like any non-Scotch whiskies, except for Japanese. They also happen to share a history of whisky making, which is why I think Japanese Whisky is very similar to Scotch.
