This is not single malt, but Old Parr is nice. It has a distincive smell (or taste?) of peat. As for a single malt whisky, I like Glenfiddich. This is from Highland. Is Glenfiddich popular in the US? Maybe. I don't know for sure because I live in Japan.
I heard Old Parr is not available in the US. This is a very old blend, probably more than 100 years old. Said to be the first whisky brought in Japan.
