In a small bowl, mix the first seven ingredients. Reserve 1-1/3 cups for basting; cover and refrigerate. Divide remaining marinade between two large resealable plastic bags. Add 12 chicken thighs to each; seal bags and turn to coat. Refrigerate for 8 hours or overnight.
Grill chicken, covered, over medium heat for 6-8 minutes on each side or until no longer pink; baste occasionally with reserved marinade during the last 5 minutes. Yield: 12 servings.
