Overview
Masterbuilt makes this vertical electric smoker with a digital control board and a patented side wood chip loader. Heat and smoke rise through the chamber, and a leg kit raises the body.
Set-it-and-leave-it controls and the side loader are the reason to buy, so wood flavor can be added mid-cook without losing smoke. The listing does not state a temperature range or rack count.
Who it's for
A backyard cook who wants to smoke ribs, brisket or sausages with a digital control board and little tending. A buyer who wants a traditional wood fire, or a portable unit, should look at a different type.
Pros and cons
- Digital temperature and time control
- Side wood chip loader
- Vertical design saves space
- Leg kit included
- Temperature range not listed
- Needs an outlet
- Heavy to move
Performance notes
A heating element holds the chamber at the set temperature while wood chips smolder to make smoke, and the vertical design lets heat and smoke rise through the meat. The side chip loader lets you add wood without opening the main door, which would let heat and smoke escape. The digital board sets both temperature and time.
