What is "chuflay"

Chuflay is the name of a traditional Bolivian mixed drink. The drink is made on the rocks in a tall glass, such as a Collins glass, with a jigger of singani and filled with either ginger ale, 7-Up, or Sprite and often garnished with a slice of lime. Chuflay is used in special events, i.e. weddings, promotions, amongst others. This drink is very affordable in most places and is served frequently.
