Playing up the tart, fruity side of Concord grapes, this drink pairs fresh purple grape puree with floral St. Germain elderflower liqueur in a variation in the classic French 75.
Note: To make simple syrup, combine 1 cup water with 1 cup sugar in a small saucepan and heat over medium heat, stirring constantly, until sugar is dissolved. Cool before using. Simple syrup will keep in a sealed container in the refrigerator for up to 5 days.

Discard the solids, stir the lemon juice into the the resulting liquid, and refrigerate if not using immediately.
