If it ends in an “e” it’s likely been made in Ireland or the States. Whisky spelled without an “e” comes from either Scotland or Canada. Scotch whisky and Canadian whisky generally taste richer and smokier. The difference, really, is in the malting process. The barley used for Scotch is dried over open peat fires, whereas the malt in whiskey is dried in ovens, which keeps its pure malty flavour.
