The Weber 18 in. Smokey mountain cooker Smoker features a generous 481 Sq. In. of cooking space across two plated-steel grill grates, enough room to smoke several slabs of ribs and a whole roast concurrently. This charcoal Smoker has a built-in lid thermometer with a smoke-zone sweet-spot identifier between 200 and 275°F that makes it easy to monitor heat and regulate accordingly with air dampers and Briquette adjustments. To keep foods moist and flavorful, a porcelain-enameled water pan is included for high-humidity slow-cooks that produce juicy, tender, professional-grade results every time.
