Weber Smokey Mountain 18" Review

The most forgiving way into real barbecue. A water pan sits between the fire and the food, and water cannot exceed 100°C (212°F), so the cooker is physically damped against running away from you.

Why the water pan is the whole trick

Beginners lose control of a fire by overshooting, then over-correcting. The WSM's water pan absorbs that energy: to climb past roughly 120°C (250°F) the cooker has to boil off water, which takes a large amount of heat, so temperature drifts slowly instead of spiking. This buys you time to react. It is the single reason the WSM has taught more people to smoke than any other cooker.

Capacity and the Minion method

Two 18 inch grates give 481 square inches, enough for four racks of ribs rolled, or two pork shoulders, or a brisket on the lower grate with sides above. Load the ring with unlit briquettes, tip a chimney of lit coals on top, and the fire burns downward and outward through the pile. That is the Minion method and it will run this cooker for ten hours or more without touching it.

Choosing the size

The 14 inch is genuinely small and best for a couple or a balcony. The 18 inch is the one to buy. The 22 inch takes a full packer brisket without trimming to fit but uses noticeably more fuel and is harder to hold steady at low temperatures because of the larger air volume.
