4. Stumps smoker: This is an insulated vertical smoker that uses a gravity-fed charcoal system. They cost around $1600.
There are many other types of vertical smokers: traditional offset smokers with the smoke stack facing the firebox, Lang offset smokers, and pellet smokers.
You will need to work hard to maintain a traditional offset barbecue smoker. Many people prefer an offset smoker to one that uses charcoal, pellets, propane. Most offset smokers require you to check the fire every 15-30 minutes. One bag of charcoal will not be enough for the big green egg or stumps smokers.
Traeger also offers larger models, including commercial BBQ smokers.
