Make the simple syrup: Combine 1/4 cup sugar with 1/4 cup water in small saucepan. Warm over medium heat, swirling sugar and water together until a syrup has formed. Allow to cool and refrigerate. Simple syrup will keep for weeks in the refrigerator.
Make the grape purée: Set aside 4 whole grapes per drink. De-stem the remaining grapes. Place in a blender with a scant teaspoon of lime juice to prevent browning. Purée the grapes. Strain the purée through a fine-mesh strainer to remove seeds, pushing it through with the back of a ladle.
To mix a cocktail, fill a small martini shaker with ice and 2 ounces vodka, 1 1/4 ounces concord grape purée, 3/4 ounces lime juice, 1/4 ounce simple syrup, 2 lime wedges and 4 whole grapes. Shake vigorously and pour contents of shaker into an old-fashioned or rocks glass. No additional garnish necessary.
