My favorite is Highland Park 12 or 18 but I had an Aberlour 12 Double Cask earlier this year that was very nice indeed. I have a nice Japanese malt, Nikka Coffey Malt (Coffey is a type of still, it's not coffee flavored) which has a nice rich chocolate note that makes it a fine after dinner dram. And - - - chilling any alcohol retards volatilization which will effect the smell (nose) of the whisky and since smell is a large part of taste, chilling will effect taste. With a nice, aged, single malt, you've paid for that flavor; you might as well get all the flavor you've paid for.
