The Full Review

The WSM is the smoker that proves you don't need to spend thousands to produce world-class barbecue. I've produced competition-worthy brisket, ribs, and pulled pork on this $399 unit.

The secret is the water pan. It acts as a heat sink, moderating temperature swings and adding humidity to the cooking chamber. Fill it up, set your vents, and the WSM will hold 225°F for 8+ hours without intervention. In a Minnesota winter, I add a little more charcoal upfront, but the principle works the same.

Two cooking grates give you 481 square inches across two levels. That's two full packer briskets or six racks of ribs. For a smoker this compact, the capacity is impressive.

The "Minion Method" — filling the charcoal chamber with unlit briquettes and adding a small amount of lit charcoal on top — is the key technique. The lit coals slowly ignite the unlit ones, giving you 12+ hours of steady heat from a single load.

More about vertical smokers

What's the easiest smoker to learn on?
The Weber Smokey Mountain (WSM). The water pan moderates temperature swings, the bullet shape holds steady heat for 8-12 hours unattended, and there's an enormous online community of 'WSM-trained' pitmasters. Competition teams have won barbecue trophies on the same $399 smoker beginners use in the backyard.
What temperature should I smoke meat at?
225°F is the BBQ standard for low-and-slow cooks (brisket, pork shoulder, ribs). Some pitmasters run at 250-275°F to shorten the cook time without sacrificing quality. Below 225°F you risk staying in the 'danger zone' (40-140°F) too long for food safety.
What wood is best for smoking?
Hickory and oak are the all-purpose workhorses — strong but balanced, work with anything. Apple and cherry are sweeter and milder, perfect for poultry and pork. Mesquite is the strongest, best used in small amounts on beef. Avoid resinous woods (pine, cedar) entirely.
Do I need a water pan in my smoker?
Yes for low-and-slow cooks. A water pan acts as a heat sink (evening out temperature swings) and adds humidity (preventing the bark from drying out too fast). Skip it only when you specifically want a drier, harder bark — most pitmasters run a water pan 90% of the time.
