Coffee BBQ rubs or Cowboy Rubs are unique blends of spices and seasonings that incorporate ground coffee to enhance the flavor of meats, particularly beef and pork, when grilled or smoked. The coffee adds a rich, earthy depth and a subtle bitterness that balances well with other traditional BBQ rub ingredients. This combination creates a complex and robust flavor profile that highlights the natural taste of the meat. The rub is applied generously and allowed to marinate, enabling the coffee and spices to penetrate the meat. During cooking, the coffee helps to form a dark, flavorful crust, adding texture and a distinctive taste that elevates the overall barbecue experience.
