With the Beefeater Vaporizer grid system, cumbersome and messy volcanic rock coated in grease and juices are a thing of the past. The ingenious Beefeater Vaporizer grid system is designed to provide maximum cooking power at the cooking surface while vaporizing juices as they fall though the grill. This vaporizing action not only gives meat that real barbecue flavor, but helps to reduce flare-ups and mess.Beefeater's Vaporizer grid system reduces annoying flare up while cooking. The optional 304 grade stainless steel heat reflector system reduces heat loss below the burners by focusing heat directly at the cooking surfaces, where it's needed. More heat at the cooking surface means faster barbecuing, less heat waste and increased fuel economy.
