In a small bowl, combine the salt, pepper, and 1 tablespoon of brown sugar. Now add the onion powder, garlic powder, and 1 tablespoon of paprika and mix until well combined.

Lay your rack of ribs on a cutting board then generously rub the spice mixture all over the top, bottom, and sides of the ribs. Make sure your ribs are well coated.

Place the seasoned ribs into your slow cooker. You can cut the rack in half if it doesn't fit perfectly. Cover and allow them to cook on low for 8 hours low / 4 hours high.

Using medium-low heat, bring a pan to temperature. Add the water, red wine vinegar, brown sugar, mustard and ketchup and mix until it is well combined. Now add the Worcestershire sauce, hot sauce, salt, pepper and paprika and continue simmering for another three minutes, stirring occasionally, until it thickens slightly.

After four hours, remove your ribs from the slow cooker and place them on a wire rack. Preheat your oven to broil. Then, brush your ribs with the barbecue sauce then transfer to the oven for four minutes. After four minutes, remove the ribs from the oven. Now they are ready to serve.
