Heat oven to 450°F. Line a 15 x 10-inch jelly-roll pan with nonstick foil.
In food processor, combine preserves, brown sugar, garlic and salt. Process until garlic is finely chopped. Remove to small saucepan. Stir in vinegar and bourbon. Bring to a simmer over medium heat. Cook 5 minutes. Add cornstarch-water mixture to saucepan; cook 2 minutes or until thickened. (You will have about 1-1/2 cups glaze.)
Cut wing tips off and discard; cut wings in half at joint for about 36 total pieces. Place on prepared pan. Remove 1/2 cup peach-bourbon glaze and set aside. Brush wings with 1/2 cup glaze. Roast at 450°F for 15 minutes. Remove pan from oven. With tongs, turn wings over. Brush with remaining glaze. Roast 15 minutes more, until juices run clear.
To crisp skin, increase oven temperature to broil. Broil wings for 2 to 4 minutes or until skin is crisp; turn and broil another 2 to 4 minutes. Serve with reserved glaze, if desired.
