An interesting regal nickname for this whisky, The Monarch. The Dewar’s 15 Y is a blended Scotch whisky from one of the most iconic whisky brands in the world. Over a century ago, John Dewar was one of the first Scotsmen to blend whisky. He was so enamored with the result that he decided to put his name on the bottle as a mark of quality. Dewar’s 15 Y features malt and grain whisky drawn from both bourbon and sherry casks.
