The universal gas roasters were developed in the 1920s to achieve maximum flavor development and the highest yield in the cup – and this goal has not changed to this day. The rotating drum inside the UG22 is equipped with special shovel blades to ensure that the coffee beans are mixed evenly during the roasting process, producing a homogeneous final product. Thanks to the smooth combination of state-of-the-art technology with an appealing retro design, the UG22 looks fabulous out on display.
