Masterbuilt Gravity Series 1050 Review

Masterbuilt Gravity Series 1050 ReviewAre you looking for an easy-to-use charcoal grill smoker with extra-large cooking area? The Masterbuilt Gravity Series might be of interest to you.

Meet the Masterbuilt Gravity Series 1050

Gravity Series 1050 Grill Smoker MainThe Masterbuilt Gravity Series 1050 model number MB20041220 is a gravity-fed charcoal grill and smoker. It is designed to be easy to use, keep a steady temperature and to keep you safe, with plenty of features for your safety and comfort.

The generous 1050 square inches of cooking area means you can produce great meals for your family and throw BBQ parties for your friends.

The large hopper holds 16 pounds of briquettes, so you won’t be continually checking it. This unit also has a controller that is enabled for WiFi and Bluetooth, you’ll be able to mingle with your guests while still keeping an eye on the cook.

Construction

The build quality is very carefully thought out both in design and costing and then is perfectly formed.

The exterior of this unit is constructed of a thinner metal like most mid-priced grills. If the metal were fit for a tank, the price would be much higher.

The inner walls of the GS 1050 are double thickness for insulation and they are porcelain-coated.

The reversible grates are constructed of cast iron for durability. If you look after this grill, I think it would last 5 years or more.

The charcoal is fed by gravity. The coals burn from the bottom only and as the lower coals turn to ash, gravity will allow more coals into the fire. The hopper is sealed so no new oxygen can enter and the Gravity Series 800 Griddle Grill Smoker Charcoal Grateonly place for the heat and smoke to go is into the cooking chamber.

Please note that wood pellets are not suitable for the Gravity Series because they will fall through the charcoal grate. The grill is designed to use charcoal and wood chunks about the size of a fist.

This video shows what is going on inside the hopper.

 

The heat is moved to the manifold by a digital fan. The manifold ensures that the heat is even distributed.

Safety Features

The Gravity Series 1050 has some thoughtful safety elements to give you some protection around this very hot beast.

The main lid switch confines the temperature to a maximum of 500F when it is open whether you’re grilling or griddling. If the temperature set is less than 500F, it will hold that heat level.

Masterbuilt Gravity Series 1050 Grill Safety Switch

The hopper lid switch and the ash door switch work together to prevent the stack of charcoal in the hopper from burning up. The fan blows air into the hopper to keep the charcoal burning, and if extra oxygen is pushed into it when you open the door this could create a chimney effect. For this reason, whenever you open either of the hopper or the ash doors, the internal fan pauses.

When the hopper lid switch or the ash door switch is released, the intelligent internal fan pauses.

Other Comfort Features

    • The warming racks fold away so they are not in the way when not in use.

Temperature Control

Charcoal smokers are infamous for being hard to use and requiring a lot of monitoring. Lots of playing with dampers and vents and testing the temperature.

There are no dampers in this unit. There is no need because it is designed to look after itself once you’ve got it going.

There is an intelligent internal fan that is dedicated to maintaining the temperature that you’ve selected. It controls the airflow between the hopper and the cooking area, meaning no vent adjustment is required by you.

A big advantage is that the digital fan will respond quickly to any adjustments you make to the temperature, either up or down. It’ll get to 225F in about 8 minutes, 450F in about 10 minutes and up to the maximum of 700 in about 14 minutes. Once it’s in operation, it’ll take about 10 minutes to reset the heat level, so you’re in charge of whether it’s set at cooking level or the intensity of a sear!

The temperature is selected with the controller unit along with cooking time, meat probe data, and countdown or count-up timer. In the image below you can also see the probe ports on the left and the on/off button in the middle.

Gravity Series 800 Griddle Grill Smoker Controller
There is an inbuilt thermometer in the lid for you to keep track roughly at a glance. It will only provide an estimated temperature because there are no number markings on the thermometer, although there are named zones indicated by black or red colors.

The thermometer is not really required because the controller is available to give you an exact temperature. I think it’s a gentle reminder of the smokers prior to the digital era.

Masterbuilt Inbuilt Gravity Series Thermometer

If you’d like the exact temperature, there is an upgraded thermometer for the Gravity Series available.

The supplied internal meat probe will ensure that the food is cooked to the correct temperature and ready to be served.

The smoke is supplied via the charcoal hopper. You can add a wood chunk every 2 inches or so as you’re adding the briquettes.

Gravity Series 1050 Grill Smoker Charcoal
If you’d like even more smoke, you could put a couple of wood chunks in the ash pan under the hopper. These will flame up and provide more smoke.

There is no water pan included in the design of this unit, but that won’t stop you from placing a flameproof container of liquid with your meat.

Seasoning The Masterbuilt 1050

  • Don’t plan on using Masterbuilt 1050 immediately because this burn-in will take a few hours.
  • Fill the hopper with charcoal to between 25% to 50% full.
  • Start the grill and set the temperature to 250F for 60 minutes.
  • Increase the temperature to 400F for 30 minutes.
  • Shut down the grill.
  • Allow the unit to cool down completely.
  • Using a clean cloth, rub a light coat of cooking oil on both grates, both racks, the charcoal grate and the inside of the lid and body.
  • Start the grill again at 350F, leave for 30 minutes.
  • Once again, shut the grill down and allow it to cool completely.
  • Ready to grill!

Ease Of Use

For a charcoal smoker, this thing is extremely easy to use; it practically looks after itself. And it’s happy to tell you all about it via the app.

How To Use The Masterbuilt Gravity Series 1050

    • Open the door under the hopper and shake give the charcoal grate a shake to make sure that the ash from the last cook is passed down to the bucket.
    • Remove the shutdown slides from between the hopper and the cooking chamber. One is the “heat intake” slide and one is the “air intake” slide; they are known collectively as the shutdown slides. These slides regulate airflow. When they’re in place, no air is getting to the fire, so guess what, it won’t light if you forget to take them out!

Gravity Series 800 Griddle Shutdown Slides

    • Spray the grates with cooking spray or olive oil spray.
    • Add charcoal to the hopper. If you’re adding wood chunks add a chunk every 2 inches or so.
    • Add a couple of wood chunks to the ash bucket.
    • Decide which grates you need and adjust as required.
    • There is a slot above the ash bucket about 2.5 inches wide immediately below the charcoal grate. Place a fire starter into the slot and push it in.
    • Make sure the lids and doors are all open to allow a flow of oxygen.
    • Light the fire starter from the bottom with a grill lighter or a wad of burning paper. If you’re using the paper method, you can throw the burning wad into the ash bucket for safety after lighting.

Gravity Series 1050 Grill Smoker Lighting

  • When the fire is lit and you can see smoke, close the lids and door.
  • Using the controller, set the temperature and time.
  • While you allow the grill to heat up you can get your food ready.
  • If you’re using the app, you can monitor the cook from your mobile phone. If you’d prefer to keep an eye on the smoker’s progress yourself, you can completely ignore the Bluetooth and Wifi features.
  • When the cook is finished, turn off the controller and ensure the lids and the door are closed. Make sure to replace the shutdown slides, otherwise you’ll waste the charcoal that was left over.

Flexibility Of The Masterbuilt Gravity Series 1050  Charcoal + Grill + Smoker

The Gravity Series 1050 has got you covered! It is a grill that becomes a smoker by switching the reversible grates.

Masterbuilt 1050 Dimensions

The cooking area is 1080 square inches in total and is made up of the two smoke/sear grates and two warming racks.

You can comfortably fit 17 chickens or 7 racks of ribs or 67 sausages or 45 burgers. Invite the neighborhood!

The dimensions of this grill are 61.02 wide and 33.7 inches deep, and it stands 52.17 inches high.

The Masterbuilt 1050 weight is 202.9 pounds, so portability is not a feature. However, it has two 8-inch wheels on the right-hand side and two 3-inch casters on the other side.

Assembly of The Masterbuilt Gravity Series 1050

Assembling the unit is pretty straightforward according to customer experience, but leave a couple of hours because there are a lot of parts. It’s a good idea to have someone available to help you with the unboxing and assembly.

The tools needed for the assembly are:

• Phillips head screwdriver
• Adjustable wrench
• 19mm socket wrench

Very helpfully, the hopper arrives already attached to the grill body.

The main assembly required is for the accessories, such as the cart and the shelves. The diagrams in the instruction manual of the Masterbuilt Gravity Series 1050 are better than average, although I think it could do with a table of contents.

A lot of the parts destined for the inside of the grill are coated in oil to protect them from rust. Maybe consider setting down a tarpaulin or paint sheet when unboxing. Plus, this oil needs to be burned off before using the grill for food, so make sure you do your seasoning!

Here is the Masterbuilt Gravity Series 1050 assembly video:

Cleaning The Masterbuilt Gravity Series 1050

  • Turn the power off at the controller.
  • Re-insert the shutdown slides.
  • Wait until the grill is completely cooled down.
  • The sear and smoke grates in the main cooking area are cast iron and can be scraped like any other grill grates. Scrape both sides of the sear and smoke grates.
  • The warming racks above the cooking area are porcelain-coated, so they can be cleaned with warm water and mild dish detergent.
  • Remove the grill grates to reveal the heat manifold.
  • Scrape the manifold.
  • Remove the grease tray, empty it, and clean it with warm water and mild dish detergent. The grease tray is on the left-hand side.
  • Slide out the bottom tray from the rear of the unit and scrape it off.
  • Spray the grill grates and manifold with cooking oil to act as a re-seasoning.
  • The ash bucket is accessed by the door under the hopper and makes emptying the ash very easy. Tap or shake the charcoal grate to knock all remaining ash into the bucket.
  • Remove the ash bucket, empty it.
  • Before replacing the ash bucket, wipe out any residue in the bucket compartment.
  • The hopper doesn’t require emptying because any remaining charcoal will be saved for the next cook. No wastage!
  • The exterior of the grill can be wiped with a damp cloth.
  • Replace the cover, store the grill in a sheltered dry place.

Storing The Gravity Series 1050

The Masterbuilt Gravity Series 1050 is an outside grill but appreciates a cover because it does not take kindly to being in the weather. An enclosed or sheltered dry spot would suit it best to keep the charcoal from getting damp and of course, the electrical control panel doesn’t do well if it’s wet.

Masterbuilt Gravity Series Troubleshooting

Temporary Lining In The Firebox

Your Masterbuilt GS 1050 will arrive with a stainless-steel liner in the lower section of the hopper. Its only purpose is to hold the firebrick in place during shipping. It is designed to disintegrate gradually after the first burn. The residue will fall into the ash bucket.

The food-grade ceramic firebrick will then be exposed and will harden with use.

The Display Says That The Grill Is Open But It’s Not

Even though it looks like all the doors are closed, they might not be quite closed. Open and reclose the main lid. You can also try pressing the lid safety switch a few times; it may be stuck. It’s at the front on the right-hand side.

The Masterbuilt Gravity Series 1050 Fan Is Not Working

The fan won’t work if the grill thinks that the hopper lid or door is open. This is for your safety. Open the hopper lid and press the safety switch a few times and then latch it firmly. If the fan doesn’t come on, do the same with the hopper door.

Ensure that you’ve set the temperature, otherwise, the fan will not come on.

During the cook, the fan will turn off and on depending on what heat and airflow the cooking chamber needs to keep a steady temperature.

The Masterbuilt Gravity Series 1050 App

Masterbuilt has an optional free app available that will allow you to control and monitor the temperature of the cook. It will also communicate various areas if it determines that certain conditions exist.
There are very mixed customer reviews concerning the apps. Some say it works as it should, some say that opening the lid of the grill causes the app to disconnect.

In short, the app is not yet perfect and it’s a good idea to still physically check your grill from time to time.

Gravity Series 1050 Grill Smoker Monitoring

Masterbuilt Gravity Series 1050 Error Codes

If you’re using the app, it may communicate certain situations with error codes. These errors are Err 1, Err 2 and Err 5 relate to the meat probe and its temperature, Err 3 warns about the grill overheating, and Err 4 warns that ignition didn’t work. Here is a summary of the codes, what they mean and what to do.

Warranty

The warranty is for 1 year, which is less than other units.

Does The Masterbuilt Gravity Series 1050 Provide Value For Money?

With the versatility to be a grill or smoker plus being so easy to use and the enormous cooking space, we think this is value for money.

Masterbuilt Gravity Series 1050 Summary

What’s Nifty About The Masterbuilt GS 1050?

  • Easily switches between grill and smoker – swap the grill and smoking grates to change mode
  • Holds steady temperature – the intelligent internal fan monitors and maintains the cooking temperature
  • Wide temperature range – this unit can go as low as 150F for smoking and up to 700F for searing and pizza plus temperatures in between for grilling
  • Fast heating up (and down) – there is no hanging around waiting for the temperature to update; the time it takes to heat up provides just the right time to prepare your food
  • Charcoal can be added without letting heat out of cooking area – no heat or smoke will escape if you need to add more charcoal; keep in mind you need to reload when the temperature is less than 250F
  • Controller enabled for Bluetooth and WiFi – thanks to the app, the controller can speak to your phone and keep you up to date with the progress of the cook
  • 4 Temperature probe ports – no more squashing the probe wires under the lid and there are 4 of them! Love it. One probe is included with the grill. The size of the meat probe plug is 3.5mm. It is a standard aux (auxiliary) style connection
  • Easy to light – this unit is lit using a fire starter and the charcoal is fed by gravity
  • Easy cleanup – there is an ash bucket and a grease tray, both easily removed, no need to empty the hopper because the charcoal is saved for the next cook
  • Safety features – when the hopper lid or door are opened, there are switches that turn the fan off to avoid a sudden rush of oxygen and subsequent flare-up plus, when the main lid is open, the temperature is adjusted to 500F for your safety, and then it returns to your set temperature when the lid is closed

What’s Not So Nifty About The Masterbuilt GS 1050?

  • Needs to be situated near an electrical outlet – yes, this is a charcoal grill, but the controller and the internal fan require electricity, so this is not a blackout grill
  • Power cord connection is fragile – the connection to the controller is a soldered join and it needs to have the tension relieved to stay attached. When you’re packing up the unit, disconnect the power cord before wrapping it around the cord hanger to protect the join.
  • Not suitable for small spaces – this unit is 33.07 inches x 52.17 inches and although it has wheels, it’s not what I would call portable
  • Short warranty – this length of warranty is not unusual among the other grills on the market, but it is quite short

How Could The Masterbuilt Gravity Series 1050 Be Improved?

Any improvements would increase the cost, of course. Having said that, a more robust power connection would be appreciated.

The performance of the app has mixed reviews, but, as with all apps, this is an ongoing project.

Who Is The Masterbuilt Gravity Series 1050 For?

The Masterbuilt GS 1050 is for someone who has room for it sit proudly in a large backyard or on a roomy patio; under cover is better. These new owners love the taste of charcoal-cooked meat, but don’t appreciate the constant monitoring required for the perfect smoky taste. They value the thoughtful safety features and the easy cleanup, which is unusual for a charcoal unit.

Tips For Best Performance Of Your Masterbuilt Gravity Series 1050

  • When you’re setting up for each cook, remember to remove the two shutdown slides to allow airflow.
  • Tap or shake the charcoal grate to release the ash from the last cook into the bucket.
  • As you add the charcoal, add a wood chunk for every couple of inches for your favorite smoky taste.
  • For even more smoke, add a couple of wood chunks to the ash bucket.
  • If you like to add a water pan, a flameproof container such as a foil tray can be placed on the grate with the food; there is no designated water pan.
  • Wear your BBQ gloves to reload charcoal during the cook; the hopper will be hot!
  • Be gentle with the power cord, try to give it some slack, and always disconnect it before winding it around the cord wrap.

Verdict

We love the size of this grill. You can feed the whole neighborhood if you want. And the easy-to-use qualities for producing a charcoal-cooked meal plus the safety features impress us.

Should You Buy The Masterbuilt Gravity Series 1050?

This easy-to-use unit would not suit someone who likes to continually check vents, charcoal and temperature. It would not suit someone who doesn’t have the room for it and if you’re looking for a griddle or a slightly smaller unit, maybe the GS 800 is for you.

Would One Of The Other Models Of The Masterbuilt Gravity Series Suit You Better?

If the Masterbuilt GS 1050 is too big for your needs, or if you’d really like a griddle as well as a grill and smoker, maybe the Gravity Series 800 would suit you. On the other hand, you might want to go a lot smaller, the Gravity Series 560 might be the one for you.

If you’d like to see how the different models compare, you can have a look at our deep-dive Gravity Series comparison article. In the meantime, these are the basic differences among the Gravity Series models.
