Diageo is the biggest dog in the room. Johnnie Walker is the world's top selling blended Scotch, and Smirnoff is the world's top selling vodka. Bailey's is the world's top selling liqueur, and while Guinness is not a spirit, the beer giant adds more heft to the overall portfolio. J&B and Bell's are both among the top selling Scotch blends.
