Originally created as a lighter alternative to Single Malts to appeal to the Americans during Prohibition, Blended Scotch Whiskies are a mix of both grain and malt whiskies that have been sourced from multiple distilleries and aged a minimum of three years in oak barrels. Nine out of every ten bottles of Scotch sold is a Blended Scotch Whisky and they are generally far more affordable than Single Malt Scotch Whiskies.
