Concord Grape and Lemon Soda

Directions

1. Zest and juice 1 lemon and put the zest in a heavy, wide saucepan. Set the juice aside. Add the grapes, sugar, cinnamon stick, salt and 2 tablespoons of water and bring to a simmer over medium heat. Stir until the sugar dissolves and cook gently over medium-low heat until the grapes have all broken down, about 20 minutes. Let cool.
2. Press the grapes and juice through a fine mesh sieve until you have a smooth puree (you should have about 3/4 cup). Discard the grape seeds and peels left in the sieve, as well as the cinnamon stick.
3. To make the soda: Cut the second lemon into thin wedges. Put several ice cubes in each of 6 tumblers. Add 2 teaspoons of lemon juice and 2 tablespoons of the grape puree to each glass. Fill with soda water and stir gently to combine. Add a lemon wedge to a each glass and serve, with stirrers if you have them.
