Key Features

Reaches 225 F in 8 minutes, 450 F in 10 minutes, or 700 F in 14 minutes
  • Includes a flat top griddle insert and cast-iron grates for low and slow smoking or high heat searing
  • DigitalFan for precise temperature control
  • GravityFed Charcoal Hopper holds 16 lbs of briquettes or 10 lbs of lump charcoal for up to 10 hours of fuel
  • Convenient fold out storage behind side shelf to prevent loss or damage to the power supply
The Masterbuilt Gravity Series is transforming the way you grill with charcoal. This innovative digital charcoal grill + smoker delivers the classic flavor and versatility of charcoal cooking, paired with the ease and precision of a pellet grill. Its GravityFed design continuously feeds fresh charcoal to the fire, while variable-speed DigitalFan technology maintains your set temperature with accuracy, controlled directly from the intuitive PID controller or your smartphone.

In just 10 minutes, it can reach smoking temperatures as low as 225 F, or climb to 700 F in only a few minutes more for a perfect steak sear. The vertical charcoal hopper holds up to 10 lbs of lump charcoal or 16 lbs of briquettes, providing up to 8 hours of consistent cooking time. As gravity pushes fresh charcoal toward the fire, spent ash drops into the bin below for easy cleanup. For shorter cooks, simply insert the included slides to cut off airflow, extinguish the fire, and save your unused charcoal for next time. Enhance flavor by adding wood chunks either to the charcoal hopper or the ash bin to generate rich, smoky notes. Heat and smoke flow evenly through a precision-engineered manifold with graduated ports, ensuring consistent results across the entire cooking chamber. The main cooking area features cast iron grates and an optional flat-top griddle insert, giving you plenty of space and versatile cooking options for entertaining any party.

Great grill and amoker

I have had the model now for two years and all I can say is wow. It works fantastic. It is easy to clean and easy to start up and be ready to either grill or smoke in less than 20 minutes. Plus with the ability to block off the firebox you save charcoal from cook to cook using only what is needed. Plus being able to add wood chucks to hopper makes for fabulous smoked meats. I have done continuous low and slow smokes for 16 hours on a single load of charcoal. See some samples as shown in included photos

Gravity Series stands at the summit with charcoal!

Charcoal inherently lacks the ability to efficiently regulate and maintain temperature. The gravity series gives you the control of a pellet or gas smoker, but with the irreplaceable taste that comes only with charcoal. There simply is no contender in this arena.

Next Level Grilling and Smoking

I've been using the 1050 now for about 3 months and it has upped my grilling and smoking game considererably. It's so easy to use by setting the desired tepature and not having to deal with fire control. I also love the thermamoter probes that connect with the app! Just set the desired internal temp and the grill alerts you when it's reached the target tempature. My family thinks I'm a master griller and smoker now but the only thing that has change is owning the Gravity 1050. Can't say enough about how much I love the results of the food and using it!

Great overall with some minor issues.

I've been using my grill for everything all summer long. Great for low and slow to high heat cooking. Everything works great with a couple of exceptions. After a handful of uses the power button on the control panel cracked. I would have hoped to see something more durable for outside use. I don't know if it is related, but the temperature probes read inaccurate temps and are unusable. I use an instant read thermometer anyway, but this is disappointing.

Game Changer!

I have been using my Webber kettle grill and an offset smoker for years. The problem is that they need constant monitoring to maintain your temperature properly. With family and responsibilities around the house, I just cannot sit around and watch my grill/smoker all day. Then came the vertical digital charcoal grill from Masterbuilt! Now I can put my meat in the smoker/grill with the temperature probes and walk away for hours! This was a game changer for me! I can go mow the lawn, go shopping, play a round of golf and not worry about my meal since I can monitor it remotely! To give you an idea of how much I use it, I go through 40+ bags of charcoal and wood chunks a year, without a hiccup! I have told all my grilling/smoking friends at work and several have purchased various sizes of the Digital charcoal grill with great success. You will not be disappointed with this!

"Best Smoker on the Market – Ribs Have Never Been

⭐⭐⭐⭐⭐ "Best Smoker on the Market – Ribs Have Never Been This Good!" I've owned quite a few smokers over the years, but nothing compares to my Masterbuilt Gravity Series® 1150. Hands down, this is the best smoker on the market for anyone who takes their barbecue seriously. I bought it mainly for smoking ribs, but it's turned into my go-to for everything — brisket, chicken, pulled pork, even pizzas on the weekends. What really makes it shine is the GravityFed charcoal hopper. It holds a full load of charcoal that slowly feeds down as it burns, meaning I can smoke for hours without touching a thing. The first time I used it, I loaded it up, set the temperature, and walked away — the temperature stayed rock-solid the entire cook. The built-in DigitalFan keeps the heat perfectly steady, and the digital controls make it simple to dial in exactly what I want. The flavor this smoker produces is unbeatable. I've used pellet grills before, and while they're convenient, they just can't compete with the rich, deep smoke flavor that comes from real charcoal. Every rack of ribs I've done comes out with a perfect bark, juicy inside, and that melt-in-your-mouth tenderness. My friends actually joke now that I've ruined restaurant BBQ for them because nothing compares to what comes off this grill. Setup was straightforward — it's a big unit, but the build quality is solid. It heats up incredibly fast too; I can go from zero to smoking in minutes, or crank it up to 700°F if I want to sear steaks. The WiFi and Bluetooth control through the Masterbuilt app is a nice bonus — I can monitor temps and timers right from my phone, which is a lifesaver when I'm hosting. Maintenance is easy as well. Ash cleanup is quick, and I like how the grease tray design keeps things neat. I've added a grill cover to protect it from the weather, and it still looks brand new months later. If you're into smoking ribs, this thing is an absolute beast. The smoke ring is always perfect, and the combination of ease, consistency, and flavor is just unbeatable. It gives that real BBQ pitmaster experience without all the babysitting. I've tried pellet smokers, kamados, and offsets — and none of them hit that sweet spot like the Masterbuilt Gravity Series 1150. It's powerful, reliable, and produces world-class results every single time. I couldn't recommend it more.

Easy to use loaded with several great features

The gravity series vertical smoker is very easy to use as both a smoker or traditional charcoal barbecue grill. The digital readouts coupled with an online application to monitor temperature and smoker time as well as internal temperature of the item you are smoking is great and allows you to set the parameters and go about your other daily tasks while the smoker does its work. The flavor of the smoked items in the gravity series is outstanding and makes my traditional gas barbecue food seem very ordinary. Has held up well thus far and I have been using it regularly for about a year now. Cleanup of the ash is also easy and neat. All around great product that has made my traditional gas grill somewhat obsolete

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.

This item leaves our warehouse within 3-5 Business Days

30-Day Returns

Return all new, unused, and unassembled items in their original packaging, and we'll give you a full refund minus the cost of the original AND return shipping.
