With over 35 years of smoking experience, we started DDR BBQ Supply with a simple goal: to help others cook better barbecue. We've spent decades learning what works and what doesn't, and we apply that knowledge to every product we carry. From high-performance grills and smokers to carefully selected rubs, sauces, and tools, everything we offer is something we believe in and use ourselves. We don’t believe in cutting corners or selling gear we wouldn’t rely on during our own backyard cooks and when we compete in BBQ competitions.
