Testing charcoal grills requires a lot of hands-on cooking, and your results will obviously vary based on your technique and ingredients, among other factors. Depending on the season and how your charcoal grill is set up, your experience cooking and grilling will likely be very different from ours. For example, a kettle-style charcoal grill left in the July sun all day will run a lot hotter than it will in the cooler spring months.
Also, a note about grill thermometers. None of the hood thermometers built into these grills mirrored the temperatures recorded by our own thermocouples and data software. It’s not uncommon for grill thermometers to read high, so we recommend keeping an oven thermometer or Bluetooth thermometer handy while you’re grilling, either for your meat or for the grill’s temperature itself.
We placed two steaks on each grilling grate near the center and seared them for five minutes before flipping them over and searing for another five minutes. With a good, reliable grill, this will give you a steak with a seared outside and a medium rare to medium center. If you prefer meat that’s more well done, you can extend the cooking time, or sear and finish cooking in an oven.
High-heat searing was our first grill test.
The best charcoal grill for steak searing in our lineup was the Weber Classic Kettle. The steak had nice grill marks while keeping a medium doneness on the inside. The worst was our Tacklife review unit, which didn’t hold much heat and didn’t sear while cooking. The steak on that grill needed an additional five minutes to get to a temperature of 135 F, the minimum for medium rare.
Chicken and indirect, medium heat
Next, we tested each grill’s medium heat cooking capability by roasting whole chickens. The trick here is to keep the grills at a hot enough temperature to cook a chicken for upwards of two hours.
For our tests, each grill gets a full chimney of lit charcoal and a 6-pound chicken opposite the coals for indirect heat.
Each grill got a chimney of hot charcoal.
Cooking over charcoal takes longer than cooking with a gas grill, and we typically need to add more fuel during cooking to keep our grills above 350 degrees F for the full duration. Our favorite bird from this batch was the one cooked on the Weber, though it was a tough call. The bird cooked on the Nexgrill cart-style grill came in right behind, a close second in terms of flavor and texture.
We cooked chicken over indirect heat until it reached an internal temperature of 165 degrees F.
The difference between the two was largely in the crispiness of the skin, with the Weber producing the superior results. Meat from the Nexgrill was delicious, with just a bit more flavor than the Weber. Between them, I’d say it largely depends on your budget and what style of grill you prefer for other meats like burgers or steak. Weber certainly had the superior sear in that category.
Low-and-slow ribs
Our last test is grilling barbecued ribs, specifically baby back pork ribs. This style of cooking requires strict temperature control over a period of multiple hours. Ideally, a quality charcoal grill (or any smoker) will keep its fire humming along close to 225 degrees F for as long as possible.
Stack your charcoal briquettes in two rows of two deep along the inner wall of the grill.
First, we set up each grill for a low-and-slow burn, using the charcoal snake method. In the case of kettle models, we arrange coals in a semicircle around the grill’s inner wall. The charcoal briquettes (Kingsford Blue) form a line two coals wide and two coals deep. We also drop a few chunks of smokewood on top of the snake (aka fuse). On cart-style grills, we modify the snake to run in right angles to match their rectangular-shaped fireboxes.
Next, we light each grill’s snake at one end of the chain with five lit briquettes (tumbleweed fire starters work, too). We set all air vents on each grill (top and bottom) to the halfway-open position. Lastly, we place one rack of ribs on each grill for indirect cooking, with the meat not sitting directly above the coals.
The classic Weber Kettle grill treated racks of ribs right.
The Weber was the undisputed king in this test. No other grill in this group could match the rock-solid temperature control of this iconic cooker. Readings from our own thermocouples, plus a digital pit thermometer, confirmed this. Throughout the Weber’s 6-hour, 32-minute cook time, the grill’s internal heat levels never strayed beyond 25 degrees of our target, 225 degrees F. In fact, most of the time the temperature hovered between 220 degrees F and 230 degrees F. As a result, ribs cooked in the Weber came out tender, juicy and full of smoky flavor.
Ribs cooked on the Napoleon grill came out tasty, though with bark that was a little dry.
The Napoleon grill was the second best in this test. Interior temperatures had a greater swing, jumping up to 300 degrees F during periods of cooking. Its rack of ribs was ready in a short 4 hours, 30 minutes. While its ribs came out tender and juicy overall, the exterior bark had a few burnt spots.
Ribs cooked on the Nexgrill had lots of bark but were juicy and tender inside.
We noted similar temperature performance from the Nexgrill, along with similar rib results. Cooking ribs low and slow on the Nexgrill required just 4 hours, 30 minutes. Its rack came out well too, though like the Napoleon, its bark was more pronounced than what the Weber produced.
Our rib experience with a few of the other grills was far from ideal. The Tacklife was particularly bad. At times, the inside of this grill hit temperatures as high as 400 degrees F. And sadly, the ribs it produced came out burned, charred and overdone.
