What's in a name? Yamazaki 60 Months Old (Rare Bottling) whisky is called whisky because it's produced in Japan. Were it from America it would be spelled Yamazaki 60 Months Old (Rare Bottling) whiskey, rather than whisky.
I am rather sorry to say that this is a blended whisky, not a single malt.
All the Suntory Royal releases, up to the current 15yo are blends.
This is an old bottle though.
