Johnnie Walker is one of the best-selling whiskies in the world. And it’s the best-selling scotch whisky by a pretty big margin. Meaning there are a lot of loyalists to Johnnie Walker’s blended scotches out there. The whisky shingle doesn’t leave its fans starving for options either, with seven core bottles in the U.S. line up and 16 active limited editions (although several of those are variations on the spendy Johnnie Walker Blue, which itself has five limited-edition expressions).
