Waterloo Sunset is a refreshing summer cocktail made with Gin, Elderflower Liqueur, Raspberry Flavored Liqueur, and Champagne. The taste of Waterloo Sunset is light and refreshing, with a hint of sweetness from the raspberries. The elderflower liqueur gives it a floral flavor, while the champagne adds a touch of effervescence. The name Waterloo Sunset refers to the classic Kinks song of the same name, which is about two lovers meeting at Waterloo Station in London. The song has a nostalgic feel to it, and so does this cocktail. The song was released in 1967, and the cocktail was created shortly afterwards. It became popular in the 1970s, when the Kinks were at the height of their popularity. Today, Waterloo Sunset is still enjoyed by fans of the band, as well as those who appreciate a good summer cocktail.
