In a large bowl or plastic bag, add the oil, chili flake, ginger, garlic, ½ can of Coke and mix thoroughly. Add the chicken wings, and evenly coat them, and place in refrigerator for 2 hours up to 24 hours.
Heat Pit Boss grill to 250°F (Low heat using a charcoal or gas grill). Place wings on the grill and cook for 75 minutes, turning as needed.
In a deep cast iron pan with a lid, mix the remaining ½ can of Coke, 1 bottle of the Gold Peak Sweet Tea, wine, vinegar, salt, onion, Pit Boss Homestyle Pork Rub, and Memphis BBQ Sauce.
Add the wings from the grill to the pan, and coat wings thoroughly. Cover the pan and leave on the grill grate.
Increase heat on the Pit Boss grill to 325°F and allow the wings to braise for 1 hour.
When finished transfer the wings to a serving plate and garnish with your choice of cilantro or green onion and enjoy.
