Brut champagne (or any other dry sparkling wine, chilled)
Steps
Fill a champagne flute 1/3 of the way with St. Germain. Top off with champagne. Gently stir to combine. Cheers!

kokociel on 2014-11-10 (5 stars): I certainly recommend trying some, but I disagree about its versatility. I would only combine it with flavours of white wine, champagne or modifications of gin.
