#1 Best Overall – Masterbuilt Gravity Series 1050

Specification :

This is definitely my Favorite Pick..
So, glad to bring you my take on this beast.
Many of us have been waiting for this for a long time.
Masterbuilt Gravity Series 1050 is also one of the biggest smokers in the list of best gravity fed smokers..
Also the best gravity fed charcoal grill in its category for price and the quality.
This is both a gravity fed charcoal grill and one of the best gravity smoker in the market at a valuable price.

The Bad

Complaints or Issues
In previous models there were complaints about the charcoal grates that the charcoal were falling off without complete burning..

The Good

Reputation and Feedback’s
This time they have come up with a complete grate design revamp.
Now it really protects the charcoal from falling off.
I am super satisfied about it.

Great job Masterbuilt.. Keep listening to feedback.
Masterbuilt already has their previous version 560 which are very well received by the smoker community.
Also there were minor feedback’s to the product.
There are huge improvements on previous versions.

A Giant
It is a giant that lets you cook a lot of items at a time.
It is 200 pounds although the box says 250.
Which means it is super heavy.

Safety 
When you are working with fans that blow the heat and smoke you should really be careful..
To provide safety from anything wrong happening.
Masterbuilt has included a safety switch near areas outside the charcoal burning box.

Cool Handles
You will get cool handles. This is great as you can avoid hand burns. 
The folding shelf is cool with a proper finishing.
I only wish it was a little bigger.
It also comes with a large bottom shelf around 8 inches tall.

Software & Connectivity
Also has Bluetooth and Wi-Fi for connectivity.
Also it has cool handles, ash pans, grease trays etc..

Already with Gaskets
The door already has gaskets on it. This is well done. It prevents the leakage of heat and smoke.
Some really cool upgrades also include the charcoal grates redesign.

#2 Best Budget – Masterbuilt Gravity Series 560

Specification :

Masterbuilt Gravity Series 560 is an earlier version of the 1050 series.
This was previously my favorite in the list of best gravity smokers. However 1050 kills it in terms of capacity.
Also we have 800 series which is almost the middle version between 560 and 1050. But I have excluded here because it is not so exciting in comparison to the other models.
Masterbuilt Gravity 560 has everything that is needed to save smoke and heat.
If you really not looking for large capacity than this smoker still stands one of the best gravity fed charcoal grill or smoker..

The Bad

Charcoal tends to fall off a few times from the charcoal grates without completely burning.
But this has been rectified in the 1050 model..
I already explained above.

The Good

Price
Everybody is not ready for an expensive smoker.
Especially when it comes to gravity smokers, the price can go very high.
However Masterbuilt has cracked it.
According to me this is one of the lowest priced gravity smokers out there in the market.

Temperature Control
The temperature control for this smoker is praiseworthy.
This is because of its double walled cooking chamber.
The 560 Digital Charcoal Grill is a fantastic multi-purpose backyard barbecue with a temperature range of 150 to 700 degrees.

So, you can both smoke and grill meat or any food.
You can reach the start up temperature really quick.
Once the initial temperature is reached it then continues to maintain it very well.

Ease of Use and Connectivity
This unit is extremely easy to use and maintain.
Its Bluetooth system is seamless and provides good connectivity.
It provides a Masterbuilt app with instructions for connectivity.
You would hardly face any problem in pairing with your phone and the WIFI.
Assembly is easy. You don’t need an expert for this.

Smoke Flavors
Initially It took me a while to perfect smoking in this unit.
But eventually I understood that it was a slight mistake at my end.
Now I feel that this smoker is better than all my other smokers. It produces great smoke flavors.

Cooling Fan
Another cool thing about this smoker is its cooling fan.
This fan is electronically controlled and regulated.
Which means that you don’t have to worry about excessive heat.

Spacious
It has plenty of cooking space. I have tried different meats such as chicken, pork butt, brisket, ribs.. Etc.
And every time I loved it…

Fuel Retention
My unit easily runs for 10-12 hours without refueling.
The charcoal lasts really long because of its highly insulated walls..

What do I love the most ?

One thing for which I am a big fan of this smoker is its compact design.
Yet, it has a good amount of cooking space.Thanks to the designers.
I heard the manufacturers have put a lot of time and effort into coming up with this.
And as far as my experience with this smoker, I feel that it is quite true.
In short, it has good temperature control, heat retention, produces clean fire and good smoke flavor..

What else is required?
It is the best gravity smoker for the money.

Helpful Tips
This unit does not come with the cover. During the rainy season or winter you may need it to protect it.

It is a good idea to get it along with the smoker..

Accessories that come handy with Masterbuilt 560.

However if I would want to take advantage of the bigger cooking space and the improvements done based on feedback for the previous 560 model then I would go for Masterbuilt 1050.

Queries Section

Some of the gravity smokers here are very versatile and best in the category.

For eg : I can go home from work, get the smoker ready for cooking at even 20 minutes and catch up with the cooking. While on weekends I can take longer duration to cook.

Both the options are viable.

Note:
There are top notch range Best Gravity Fed charcoal Smokers in the market like the Vulcan gravity feed smoker series from Myron Mixon, stump smoker, old country gravity fed smoker which I have excluded in my list.

Simple reason is for its cost and availability..

# Old Country BBQ Pits Insulated Gravity Fed Charcoal Smoker

---

If you are looking for a fully insulated gravity smoker, then Old Country Gravity Smoker is one of the best insulated gravity smokers out there. 

However I have not included it here in my list as its availability and support is an issue.
Moreover I was more keen towards a vertical model, but damn it was not easy to even find it.
As of writing this review, there are no vertical options for this smoker.
Most of the time in academy.com it’s out of stock and a struggle to buy. And I didn’t want to refer to something which is not readily available.
Service and support is a critical thing for me. And I am not very positive about this too.

# What is gravity feed smoker?

Gravity smokers are a kind of smoker which uses the weight of the charcoal wisely in its design.
Because of its clever design, the charcoal does not require manual attention to keep burning.
Which means that you can put charcoal in the hopper, start the smoker. But you don’t have to babysit to control the temperature.
This smoker’s burn up time can range from 10 hours up to 20 hours.

# How does a Charcoal Gravity Fed Smoker work?

Gravity Fed Smoker works on the principle of a sealed environment which means it does not allow the heat to pass through its walls.
The amount of the fire is controlled by the air passing through the valve to the fire box chamber.

The fuel in it takes time to burn as fire takes time to travel in the whole of a chamber.
This is due to the lack of oxygen in the cooking chamber, this condition is called oxygen depletion.
The fuel burns to continue when the oxygen depletion is overcomed.
The oxygen supply is from the bottom bottom(4-5inches) of the chute and takes a little time to burn the whole fuel.
The air passes through the valve across the chute and burns the entire fuel.
The tube inside the chamber passes the heat and smoke to the cooking chamber.
The divider plate inside the cooking chamber distributes the heat and smoke evenly throughout its compartments.

# How to use Gravity Fed Smoker?

Here is a video guide  on how to use this smoker. But the example shown below is of an old country gravity smoker..
Which means that  the real working can vary with specific brands and models. But sure enough you will get an idea of the working principles.

# Gravity smoker vs pellet grill. What is the difference?

The basic difference between the gravity smoker vs pellet grill is that gravity uses charcoal as a fuel, where as pellet grill uses different wood pellets as its fuel.
However below table should help you get a quick picture on their other differences.

Gravity Smoker	Pellet Grill / Smoker
Gravity smokers  use Charcoal as a fuel . Works well with charcoal lumps and briquettes.	It Is mainly designed to use pellets as a fuel
Gravity smoker can produce stronger smoke flavors	Pellet smoker produces lesser smoke flavor in comparison to gravity
Gravity smokers  operate by using gravity as the core technique along with the use of automatic fans.	Pellet smokers operate mostly using PID controllers.
Gravity smokers can last longer hours.	Pellet smokers may last lesser hours  in comparison to gravity smokers.
Gravity smokers do not require much attention as it is fully automated. It is like an offset smoker levelled up;..	Pellet smoker although automatic can require manual attention to refill . Sometimes Auger gets blocks and you may need to check once a while.
Similarities
Beginner Friendly
Requires lesser manual attention than offset smokers or other types of smokers.
Gravity and Pellet Smokers both can produce smoke rings, although experience plays a role here.

# Gravity smoker vs offset. What is the difference?

Gravity Smoker	Offset Smoker
Gravity Smoker works best with Charcoal lumps and Briquettes.	Offset Smoker is best with woods and Charcoal.
Gravity Smoker is designed to for ease of use and to save time	Offset smoker requires a lot of time and manual attention.
Gravity Smoker is beginner friendly	Offset smokers are not so beginners friendly
There are not many options for Gravity Smokers	There are lot of options for Offset Smokers
Gravity smokers may or may not produce results like Offset smoker. However this purely depends on personal choice on what’s best for you.	If properly fire managed , results in offset smokers are usually considered to be better than quick smokers.
Gravity Smokers are like Offset smokers on steroids	Offset smokers I feel are more like the old and the expert way of smoking.

# Gravity fed horizontal smoker

Gravity feed horizontal smoker simply got its name because of its design.
Very few brands are building this type of smokers.
When it comes to horizontal smokers the first brand that comes to my mind is Stump.
Although most gravity smokers are already horizontal, they simply have clear branding with the name.
Honestly I am not a big fan of these smokers. It’s just the design and the huge price tag that kicks me off. But yes they have their own uniqueness and quality for sure. 
I can’t say much about these smokers as I have very little information around it to share it as a value.
Here is a link incase for you to check out different ranges of Gravity Fed Horizontal smoker.

No. You can always control it. Once you are done with  the smoker.

This is common.

And incase you don’t know. Creosotes are bad for health. There is a study on even how creosote can affect both children’s and the adults.
Therefore I recommend using good quality charcoal. For eg :- Oak wood charcoal, Masterbuilt own charcoal.
This should avoid the creosotes in Masterbuilt 1050 series too.
