The Myrtille Fizz is essentially a liqueur-based Spritzer tall cocktail. Refreshing and easy to make, the Myrtille (blueberry) Fizz is a perfect libation for a relaxing, easy, lazy Sunday afternoon. Perhaps simple but this concoction is packed with flavours. We use the excellent French producer Giffard for its great taste. This fabulous fizzy drink can be made stronger by simply adding a splash of your favourite vodka.
