Soak wooden skewers in water for at least 30 minutes if using bamboo skewers.
In a small saucepan, combine the barbecue sauce, bourbon, brown sugar, honey, Worcestershire sauce, garlic powder, smoked paprika, and black pepper.
Bring the mixture to a gentle simmer over medium heat and cook for 5 to 7 minutes until slightly thickened. Remove from heat and allow it to cool.
Wrap each piece of chicken with half a slice of bacon and thread onto the skewers.
Preheat the grill to medium-high heat and lightly oil the grates.
Place the kebabs on the grill and cook for about 12 to 15 minutes, turning frequently for even cooking.
During the final few minutes of cooking, brush the kebabs generously with the bourbon BBQ glaze. Continue turning and glazing until the bacon is crisp and the chicken is fully cooked.
Remove from the grill and let the kebabs rest for a few minutes before serving.
Garnish with fresh parsley or green onions if desired and serve warm.
