Dewar's was started by John Dewar Sr, a wine & spirits merchant, but the company really got going by his sons, John Alexander and Tommy. Dewar's White Label is comprised of over 40 different malt and grain whiskies. Comprised of both single malts and single grains often from many different distilleries. Dewar's White Label is nothing short of a fantastic mixer. Blend it with sweet vermouth and bitter for a classy Rob Roy. For something subtler, combine equal parts Dewar's White Label with amaretto for a delicious beverage.
