In a small bowl, stir together turbinado sugar, coffee grounds, paprika, salt, garlic powder, onion powder, orange zest, and red pepper.
Pat ribs dry. Using a sharp knife, pierce thin membrane on back of ribs; peel off, and discard. Sprinkle both sides of ribs with coffee mixture. Cover with plastic wrap, and refrigerate overnight.
Preheat oven to 225°. Line a large rimmed baking sheet with foil, and top with a wire rack. Place ribs on prepared pan.
Bake until a meat thermometer inserted in center registers 195°, 7 to 8 hours, depending on thickness of ribs. Let stand for 10 minutes before serving.
