Besides charcoal, other fuels can be used in the barbecue Verticook®, such as small tree branches or logs provided that they are small enough to enter easily in the firebox. Their calorific content should be high enough (coco nut briquettesare not convenient for example).
Flames that could appear in the firebox are not a problem since the fumes evacuate upwardly and vertically. Neither the flames nor the smoke they create will come in contact with the food. Thus, there is no need to use high quality charcoal which is usually expensive.
The barbecue Verticook® is beneficial for the environment.
