Preparation: Pour the plum wine and syrup into a champagne glass. Fill glass with champagne, poured down the glass' side.
General Comments: Another one of those simple layered cocktails, that starts off as close to champagne and gets increasingly interesting as you go. The plum wine shows up fairly soon, providing sweetness and tang, The vanilla doesn't really kick in until the end, which in some sense is a shame, but it does give the drink a powerful "happy ending", assuming of course the idea of a mouthful of almost pure syrup mixed with plums, booze and bubbles appeals to you.
It's not really a particularly interesting cocktail, in terms of taste, look, or (especially) name, but it's solid enough.
