What is "cold duck"?

Cold Duck is a type of sparkling wine cocktail that was popular in the United States in the 1960s and 1970s. It is typically made by combining equal parts of red wine and sparkling wine, such as Champagne or Prosecco, and sweetening the mixture with a dash of sugar or orange juice. The drink is served chilled in a tall glass or a champagne flute, and may be garnished with a slice of orange or a sprig of mint. Cold Duck has a sweet and fruity taste, with the red wine providing a rich and complex flavor that is balanced by the effervescence of the sparkling wine and the sweetness of the added sugar or juice.
