Pit barrel BBQ — low & slow grilling in a vertical smoker
A pit barrel — also known as a drum smoker or vertical smoker — is one of the simplest and most effective low & slow devices available. The principle is radically different from a kettle or offset smoker: meat hangs vertically on hooks above the coals, and heat rises evenly around the meat. No grates, no turning, no basting. Just hang and wait. This guide explains how a pit barrel works, what makes it unique, and how to get the most out of it.
How does a pit barrel work? The principle explained
A pit barrel is a 200-liter steel drum with coals at the bottom, air vents on the side, and a lid on top. Meat is hung on hooks via rods that rest across the top of the drum — the meat dangles vertically above the glowing coals. This vertical hanging has three direct consequences that distinguish the pit barrel from all other BBQ devices.
Hot air rises along the inner wall of the drum and circulates around the hanging meat. The meat cooks evenly from all sides simultaneously — there is no “colder” or “hotter” side as with a grate. This means: less turning, less checking, more even cooking.
Fat and moisture drip from the hanging meat directly onto the glowing coals. This fat burns and rises as aromatic smoke that immediately envelops the meat. This is why meat from a pit barrel has an intense, deep smoky flavor that is difficult to replicate with a conventional setup.
A pit barrel typically operates at 150–175°C — higher than the 110–120°C of a classic low & slow setup. This sounds counterintuitive, but the combination of convection heat, vertical hanging, and constant smoke compensates for the higher temperature. Meat in a pit barrel is juicier than expected based on temperature alone.
Due to the higher operating temperature, cooking times in a pit barrel are shorter than with a classic low & slow setup. Spareribs: 3–4 hours instead of 5–6. Pulled pork: 5–6 hours instead of 8–12. Plan based on internal temperature and texture, not on standard low & slow times. More about testing doneness: Temperature, time, and texture — testing doneness in BBQ.
Which meats work well in a pit barrel?
| Meat | Hanging technique | Cooking time (approx.) | Special features |
|---|---|---|---|
| Spareribs | Hook through the bone at the thick end | 3–4 hours | Bend test for doneness; no need to remove membrane in pit barrel |
| Pulled pork (shoulder) | Hook through the bone or upper meat | 5–6 hours | Rest before pulling; internal temperature 90–95°C |
| Whole chicken | Hook through the neck or wings | 1.5–2 hours | Skin becomes crispy due to fat dripping onto coals |
| Brisket | Hook through the point, flat hangs down | 4–6 hours | Check the flat for drying out; optionally wrap after 3 hours |
| Lamb shoulder | Hook through the bone | 4–5 hours | Combination of convection heat and fat-on-coals gives intense flavor |
Small or thin cuts of meat — chicken wings, burgers, fish fillets — cook too quickly and are harder to control on a hook. For these, use the grate that comes with most pit barrels, or choose a different BBQ setup.
Fuel and temperature in a pit barrel
Most pit barrels work with charcoal — not briquettes. The higher combustion temperature of charcoal suits the operating temperature of 150–175°C. Briquettes can also be used but give a lower peak temperature and would need to be used in larger quantities.
Fill the coal basket at the bottom of the drum ¾ full to completely full. A full coal basket in a standard 200L drum provides a burn time of 4–6 hours at the operating temperature. Use the manufacturer's recommended amount as a starting point and adjust based on your experience with your drum and the ambient temperature.
Temperature control in a pit barrel is different from a kettle. There is usually one air vent on the side — that's your only control knob. More open = higher temperature. The lid has a small vent hole that must always remain open — never close it completely, otherwise you will smother the fire and get bitter smoke.
Place 3–5 wood chunks directly on the glowing charcoal before hanging the meat. The chunks will immediately start to smoke and give off the most smoke in the first 1–2 hours — precisely when the meat absorbs the most smoke. Chips work less well in a pit barrel due to the high heat; always use chunks at least fist-sized.

Rub and marinade in a pit barrel
The pit barrel is pre-eminently a device for dry rubs. The convection heat and continuous smoke dry the rub surface evenly and build up a solid bark — around the entire piece of meat, not just on top. A marinade or wet sauce is less suitable: the high operating temperature and dripping fat mean that sugars in a wet marinade quickly burn on the outer surface.
Apply the rub generously — all sides, including the underside of the hanging piece. After hanging, the rub does not drip off; the heat dries it immediately. Let the rubbed pieces stand at room temperature for at least 30 minutes before hanging so the rub adheres well.

Pit barrel vs kettle vs offset smoker
| Pit barrel | Kettle BBQ | Offset smoker | |
|---|---|---|---|
| Operating temperature | 150–175°C | 110–180°C (adjustable) | 110–135°C |
| Cooking style | Vertical hanging, convection | Lying on grate, indirect heat | Lying on grate, horizontal smoke |
| Smoke flavor | Intense — fat on coals | Moderate — wood chunks on coals | Very intense — continuous smoke |
| Difficulty level | Low — little adjustment | Medium | High — constant monitoring |
| Cooking time | Shorter than classic low & slow | Standard low & slow times | Longest cooking times |
| Capacity | Large — multiple pieces at once | Limited to grate surface | Large |
| Price | Mid-range | Low to mid | Mid to high |
