You can blend whiskey with everything from milk and tea through to pickle juice and apple cider. It also pairs exceptionally well with soda. The soda that is most frequently used with whiskey is Coca Cola. However, whiskey can also work incredibly well with lemonade, ginger ale, and even Mountain Dew.
Tennessee bottlers Barney and Ally Hartman developed Mountain Dew as a mixer in the 1940s. Soft drinks were sold regionally in the 1930s, and the Hartmans had difficulty in Knoxville obtaining their preferred soda to mix with liquor, preferably whiskey, so the two developed their own.
