Place pork in a slow cooker. In a small bowl, stir together brown sugar, salt, loose tea, black pepper, garlic, and red pepper; sprinkle over all sides of pork shoulder. Add onion and garlic to slow cooker; pour brewed tea over pork and vegetables. Cover and cook on high until meat is fork tender, about 5 hours.
Remove from slow cooker, reserving cooking liquid; shred meat with 2 forks. Add cooking liquid as desired for extra flavor and moisture. Serve with Peach-Sweet Tea Barbecue Sauce.
