We all know there are many choices out there in the way of kettle fuel – but what does each unique brand or product line bring to the table? and is there really a measureable difference between how much ash they produce? Let’s take a closer look at 4 of the more readily available briquette offerings from Kingsford, Trader Joes and Stubbs and see how they stack up.
I will be the first to admit this is not the most scientific or controlled test in the world, but I hope it at least gives everyone a glimpse at some real world results and a better understanding of which charcoal is right for the job.
Simple items used for the test:
4 Large Weber Charcoal Chimneys
4 Weber lighter cubes
4 Pans to collect ash
1 Digital Scale
and a selection of charcoal.
Since the goal was to weigh the ash at the end of the burn, I decided to base the test on weight and not the number or quantity of briquettes used. Each charcoal chimney was filled up as close as possible to 7lbs loaded. Considering the empty chimneys weight just a hair under 2lbs that leaves us with 5bs of raw material being used.
The competition briquettes are substantially lighter than all three of the other offerings which I found quite interesting. They had a fairly even consistency and held their form well. Take a look at how much more of the chimney the Kingsford Comp fills due to its low density.
The Trader Joes has a reputation of being crumbly and I would have to agree. The briquettes are very rough and tend to break apart fairly easily when you move or pour them into the cold chimney. There was a large black pile of soot sitting down below after dumping in a fresh load from the top of the bag. This was the only one of the three to exhibit this so perhaps they are using a less aggressive binder. I’ve gone through a few bags of this now and have noticed one other thing that bothers me a little bit. In almost every bag I find a few briquettes that appear to have some sort of plastic fibre stuck within. This is consistent over multiple bags so its not just a random occurrence and definitely doesn’t appear to be a natural fibre to me…
The Stubbs briquettes are very dense and finely ground. Not many rough bits at all here – smooth to the touch and evenly packed. These briquettes are also smaller than both the Kingsford and Trader Joes by about 30%. Because of this smaller form factor it packs together tighter and therefor allows you to preload more fuel into the baskets, chimney or cooker.
And finally the tried and true Kingsford Blue Bag. Visually almost identical to the Comp but each briquette is noticeably heavier. Slight dust left behind but hardly enough to even worth mentioning.
All four chimneys were then lit at the same time using one Weber firecube each.
Here is video showing how much smoke each chimney puts off for the first 5 min of start up.
I also started the timer 5 min late so these first shots are actually 25 min in…
From Left to Right: Kingsford Comp and Trader Joes
…Stubbs and Kingsford Blue
The Kingsford comp is definitely throwing more heat than the other 3 chimneys. You can see a large flame collecting in the middle of the chimney already and it’s glowing orange more than the others as well.
Here we are 45 min in:
You can see how fast the Kingsford Comp is losing mass as it burns. At this point it has already burnt down significantly – enough that the charcoal level in the chimney in now equal to other three briquettes.
We’re now an hour in and fuel is starting to run low…
1:15… still going…
Here we are at an 1:30min – Comp just barely hanging on:
And finally after roughly 1 hour and 37min (adjusted) the 5lbs of Kingsford Comp was shot!
Second to die was the Kingsford BB 12min later @ 1 Hour and 49min:
Third to go was the Trader Joes only 5min later @ 1h 53min
And finally the Stubbs just 3 min behind the Trader Joes @ 1h 56min
So final burn times were:
1:37min Kingsford Comp
1:49min Kingsford Blue
1:53min Trader Joes
1:56min Stubbs Briquettes
The Comp decisively died off the fastest but the other three came in surprisingly close within only minutes of each other.
So how about ash?!?! Here’s a visual of the ash piles before moving and weighing:
To make the weight fair they were all measured in the same pot which weighs 13.15 oz.
Leftover Dry Ash Content Breakdown (bucket weight subtracted out):
Kingsford Comp: 5.9 oz
Trader Joes: 9.4 oz
Stubbs: 10.1 oz
Kingsford Blue Bag: 10.7 oz
The Kingsford Comp was the clear winner in this regard coming in at almost half that of the competitors. Once again the TJ’s Stubbs, And KBB came out very close on paper.
For high-heat grilling and searing I would definitely recommend the Kingsford Comp. I was quite surprised at the heat difference coming off the Comp as opposed to each of the other chimneys. They Comp you could stand 4 ft away and still feel the heat – the others were 3′ or less. The obvious downside to this high heat burn is the overall shorter burn times that it produced – so I would suggest going with one of the other three offerings for longer smokes and burn times. Of the three, the Kingsford Competition also smoked noticeably more on lighting with a thick white smoke that could be annoying to some.
Close behind was the KBB with slightly less dense white smoke, but the smoke itself I find very irritating to my eyes and lungs. As many have noted in the past it has a much more “chemical” smell and burn to it that the Comp and especially the TJ’s and Stubbs.
TJ’s – If it weren’t for the crumble and synthetic hairs this would be right at the top of the list with the Stubbs and is a great choice for a readily available and AFFORDABLE briquettes. 100% Natural (or so they say!) Less smoke than both the Kingsford products and almost on par with the Stubbs. This is good go-to standby that I would not hesistate reaching for
Stubbs Briquettes – These have been my go-to charcoal product for the past few months so I was happy to see the results I was experiencing at home translate over into the final numbers. The combination of long burn time, solid construction, size and most importantly an all natural clean burn were enough to push it over the top and past the other competitors in the challenge. If you can find this stuff locally I would highly recommend giving it a shot – especially if you can snag it on sale.
So there you have it – some real world results on some of the most common charcoal briquettes available. Now that you’ve done some homework I encourage you to experiment with a few different types yourself and see what works best for you.

Great review. An infared thermometer throughout the test would have been nice, so you could compare temperatures.
Temperature comparisons are planned for the next round of test so stay tuned 🙂
That’s a good basic test. I would like to see how lump will stand up to the others. Thanks!
Great review! Thanks for sharing. I have used all of these coals and found this very useful. Quick question though. You said that TJ’s brand is readily available? Do you live in Cali? I stocked up on 4 bags here in ATL because it looks as though it is seasonal. I did luck out the other day at my Trader Joes though. I asked if they had any more and all they had was two full bags that were ripped so they had to pull from selling and the manager gave them to me for free! I heard there is a another brand that is the same stuff with a different name. Any idea what that is? Thanks again!
I pick up the Trader Joes briquettes from the store in Bellingham WA. They usually had a at least a partial pallet of it when I stop in so I just assumed it was a regularly stocked item. Will ask next time I’m down…
Stubbs is the go to n my book…and one of the least expensive to boot!
Non-sale, normal price is $6.98 for a 15 lb bag at my local wallyworld!
I get 15 hours of burn time per 1/2 bag (7 lbs) of Stubbs in my LSG insulated vertical! 15 hours for $3.50! Simply can’t be beat!
Interesting test. Thanks for posting it.
I’m sticking with the Kingsford Competition for grilling (Weber) and smoking (Weber Smokey Mountain). For a long cook, high heat and less ash are huge. Less ash means better control of the heat in the long run. At the end of a cook, if your smoker is full of ash, there is no room for air under the coals, which makes it hard to keep the heat up.
In this open air test, I’m not surprised to see the Comps burn out first. It would be interesting to see the same test in a smoker, limited air flow and a chart of the temperatures over the long run.
Very true JMan. But the flipside of that is the notion that shorter burns will mean more to be added; that is, you’ll have to stoke the fire more times than with longer burning fuel. More briquettes means more ash. The real test would be to compare the amount ashes left after a long smoke session. Also, are you losing heat every time you stoke it? You’d need a thermometer to track the internal heat over time.
My guess would be that loner burning coals actually produce less ash per BTU of energy. Coals don’t burn at 100% efficiency (nothing does), hence the more briquettes that are added means more of the incombustible byproducts that would accumulate. According to Wikipedia, “Lump charcoal … usually produces far less ash than briquettes.”
My suggestion would be to use whichever method requires the lowest total number of briquettes (or lumps), while still maintaining the temperature you desire.
Thanks Mat, A great piece of work!
