This review delves into the performance of Kingsford Low & Slow charcoal briquettes during a rigorous 17-hour barbecue test. We subjected a 12-pound bag to the demands of low-and-slow cooking, aiming for a consistent 250°F temperature in an 18-inch Bronco charcoal grill. The test incorporated techniques for even heat distribution, including the use of a Weber cube and careful ventilation management. This in-depth analysis focuses on the briquettes' ability to maintain a stable temperature over an extended cooking period, ultimately assessing their suitability for serious barbecue enthusiasts.Our experiment centered on back ribs, cooked for nearly 18 hours. We meticulously documented temperature fluctuations, noting the impact of external factors like wind on the grill's performance. This detailed account examines not only the total burn time of the Kingsford Low & Slow briquettes but also their consistency in maintaining the ideal temperature range for low-and-slow cooking. The results reveal crucial insights into the longevity and temperature stability offered by these briquettes compared to other brands.
Pros And Cons
- Lasted for 17 hours and 44 minutes at a temperature around 250 degrees Fahrenheit, with minimal fluctuation.
- Maintained a consistent temperature even with wind.
- Provided sufficient burn time for long cooking sessions (e.g., brisket, back ribs).
- Requires refueling after approximately 17 hours of use.

Setting Up the Cook
I started by prepping my 18-inch Bronco charcoal grill. This particular grill's charcoal basket is designed to hold 8 pounds of briquettes. I used a 12-pound bag of Kingsford Low & Slow briquettes and supplemented it with pecan wood chunks for added flavor.

Following my usual method, I placed a Weber cube at one end of the charcoal basket to help with consistent burning throughout the cook. This technique ensures even heat distribution across the entire grilling surface.

The goal was to achieve and maintain a consistent 250°F temperature inside the grill. A steady temperature is crucial for low and slow barbecue, allowing for maximum tenderness and flavor development.
Maintaining Temperature
With the briquettes lit and burning, the Bronco grill quickly reached the target temperature of 250°F. Despite a noticeable wind, the grill maintained a steady temperature.

To manage the heat and prevent the briquettes from burning too quickly, I adjusted the top smoke stack and side intake vents on the Bronco. This fine-tuning helped to maintain a consistent temperature throughout the long cook.

The challenge during long cooks is preventing rapid briquette burn-off. Careful ventilation control is essential for maintaining the desired temperature for extended periods.

The Long Cook
The back ribs were placed on the grill once the temperature stabilized. Over the next several hours, the grill consistently held around 250°F with only minor fluctuations.

Even with the wind, the temperature remained surprisingly steady. This demonstrates the effectiveness of the ventilation controls on the Bronco grill in managing heat.

Throughout the extended cooking period, the grill's temperature remained remarkably consistent, showcasing the long-lasting burn of the Kingsford Low & Slow briquettes.

Results and Conclusion
After an impressive 17 hours and 44 minutes, the grill's temperature finally dropped to 225°F, signaling the end of the briquettes' burn time. This long burn time is remarkable, exceeding many other brands.

The Kingsford Low & Slow briquettes demonstrated exceptional performance in maintaining a consistent low temperature for an extended period. The ability to hold a steady temperature for over 17 hours is highly impressive.

Overall, the Kingsford Low & Slow charcoal briquettes proved to be an excellent choice for low-and-slow cooking. Their sustained burn time and consistent temperature control make them a worthy investment for serious BBQ enthusiasts.
