Made with elderflower liqueur (elder = senior, get it?), this turned out to be wonderfully refreshing, whether you try the high-test version or the vodka-free. Fill a highball glass with ice and add 1.5 ounces citrus vodka, 2.5 ounces St. Germaine, .5 ounce Chambord and fill the rest of the glass with a slightly off-dry sparkling wine. Finish with a lemon twist. For a lighter version, omit the vodka. Yum.
