Make the sauce by mixing the bourbon, BBQ sauce, soy sauce, honey and brown sugar.
Cut the rack of ribs in half to make it easier to fit in the oven and grill. Place the ribs in a bowl or large bag and cover with sauce. Marinate in the fridge for as long as you can. I did about 5 hours. At least 2 hours is good enough if you don't have all day.
Preheat the oven to 250 F. Place the ribs on baking sheets and cook in the oven for 3 hours, flipping once after 1 1/2 hours. Baste the ribs with additional sauce about every 30 minutes.
Heat the grill to medium high. Place the ribs on the grill and baste one last time. Cook for 7-10 minutes on each side.
If you don't want to finish the ribs up on the grill, you can heat the oven to 400 F and cook for 7-10 minutes on each side.
