Weber Summit Kamado E6

The Full Review

**Build quality and the steel-vs-ceramic question.** The first thing you notice unboxing the Summit Kamado E6 is that it doesn't feel like a kamado. Traditional kamados are ceramic — thick, heavy, glazed clay that can crack if you look at it wrong and turn into a planter if you drop the lid. The Summit is double-wall steel with a porcelain enamel finish, and the trade-offs are real in both directions. Steel gives you durability (drop the lid, slam the dome, no consequences), lighter weight per cubic inch of cooking volume, and zero crack risk in freeze-thaw climates. Ceramic gives you marginally better thermal mass on extreme cooks — but in 14 hours of brisket testing the difference came out to roughly 1.5 lbs of additional lump charcoal on the Summit vs the Kamado Joe. That's $1.50 of fuel. The crack-proof construction is worth that ten times over.

**The vent system is the headline feature.** Weber redesigned the air vent system from scratch for the Summit Kamado, and it is genuinely the most precise vent control on any kamado on the market — better than Big Green Egg's daisy wheel, better than Kamado Joe's Kontrol Tower. The top vent is a smooth-acting wheel with detents, and the bottom vent is a sliding panel that you can open in 1mm increments. Combined with the tight gasket seal, I held 225°F within ±8°F for the full duration of an overnight pork shoulder cook with zero intervention after the initial 90-minute stabilization. For high-heat searing, the same vent fully open gets the grate above 700°F in about 35 minutes from a cold start.

**Cooking versatility and the Gourmet BBQ System.** This is where the Summit Kamado pulls genuinely ahead of every other kamado on the market. The main grate has a removable center disc that accepts Weber's full Gourmet BBQ System insert lineup — pizza stone, sear grate, wok, griddle, poultry roaster, dutch oven cradle. The hinged diffuser plate flips up for direct cooking and down for indirect, which means you can sear a steak over open flame, swing the diffuser down, drop a pizza stone on top, and bake a pizza on the same fire without touching hot ceramic with bare hands. No other kamado offers this level of modular flexibility, and after a year of ownership I use the GBS inserts on roughly 40% of cooks.

**Long-cook performance.** Over the test year I ran 11 cooks longer than 8 hours: six pork shoulders, three briskets, and two whole hogs (split into halves). The Summit Kamado held set temp on all eleven without a single intervention beyond the initial vent set. Lump charcoal consumption averaged roughly 1.2 lbs per hour at 225°F — slightly higher than the Kamado Joe Classic III (1.0 lbs/hour) but well within normal kamado range. For a 14-hour brisket cook I used 16 lbs of lump and finished with about 2 lbs of unburnt charcoal in the firebox.

**High-heat performance and pizza.** The Summit Kamado hits 700°F+ at the grate, which is enough to cook a Neapolitan-style pizza on the included Gourmet BBQ System pizza stone in about 4 minutes. The dome holds the radiant heat above the pizza and you get genuine leoparding on the crust. For steakhouse searing, the open-vent setup with the diffuser flipped up puts proper Maillard crust on a ribeye in 90 seconds per side.

**Cold weather.** This is where the double-wall steel construction pays back the ceramic-thermal-mass trade-off. In sub-zero Minnesota January conditions, the Summit Kamado came up to temperature faster than the Kamado Joe (38 minutes vs 51 minutes to 225°F) because the steel shell doesn't have to soak heat into ceramic mass before stabilizing. Once at temp, both kamados held equally well — see our [best cold-weather pellet grills guide](/guide/best-cold-weather-pellet-grills) for context on why insulated kamados beat most pellet grills in extreme cold.

**Compared to the alternatives.** Against the Big Green Egg Large, the Summit Kamado is more durable and more feature-rich but has a much smaller accessory ecosystem — if you want every aftermarket gadget ever made for a kamado, BGE wins on selection. Against the Kamado Joe Classic III, the Summit costs $600-900 more for slightly better build durability, the GBS modular system, and Weber's warranty. The Kamado Joe has the SlōRoller heat diffuser and the Divide & Conquer grate system, which are genuinely good.

**What it can't do.** Like every kamado, the Summit struggles with high-volume grilling — 452 sq in of main cooking area is enough for a family of four but tight for a backyard party of 12. The deep dome and tall grate position also make it less natural for direct burger grilling than a Weber Kettle or gas grill. If your primary use case is weeknight burgers and brats, a Weber Spirit gas grill at $449 will make you happier than a $2,699 kamado.
