With travel opening up again around the world, and particularly in the UK, whisky tourism is slowly getting back into the swing of things. And no whisky pilgrimage to Scotland would be complete without swinging by Speyside and dropping into a distillery or two. Or three. Or twenty. In fact, for those looking to make a specific trip of it, Alastair Rooney’s new book, “The Speyside Whisky Trail” is the perfect guide for discovering a lot about Scotland and visiting 20 distilleries along the way.
