Pretty much any single malt from scotland especially the McCallan if you like smooth, almost any decent IrIsh whiskey , Penderyn from WAles and a great many of the Japanese ones. I also recommend the English Whisky company especially the peaty one can't remember it's number, I find Jim Beam and the other US ones too monochrome for my taste even the higher priced versions. Too much oak swamps the subtle flavour range. I think it's best not to compare against real whisky but treat Bourbons as a totally separate animal.
