Introduction
"For those who have received their new KEC, including the last 4 days of our cooking with the KEC, it is clearly the best. The briquettes are hard and look like they are 'hand made' which they are. The hole in the center is a little smaller and the briquettes are a little longer, hence the higher weight. 100% pur (sic) coconut shell charcoal."
"A pallet of Kamado Charcoal will be a gift that keeps giving all summer! We are shipping pallets, at wholesale prices, from our new charcoal factory."
"MANUFACTURING: We are manufacturing ourselves with quality control our priority. We are using 100% coconut shells with 100% control over the process. This will result in a much dryer (sic) and less ash content. The performance is much the same as our best KEC, but better. The burn test picture is indicative of our frequent testing of our KEC briquettes."
"Kamado Extruded Charcoal Customer Report. We are very pleased to report that our own
manufactured KEC is the best we have sold."
Once again Kamado is claiming to be selling the best charcoal they have ever sold. So, is Kamado really selling good charcoal this time around, or are they selling more low-quality charcoal as they have been since they stopped selling the Philippine charcoal? Obviously, a new review is in order.
A Little History
Now, it appears that Kamado is selling yet another type of coconut charcoal briquettes, apparently again made in Indonesia. So we have obtained a sample, conducted all the tests and recorded all the results in this review.
One last note about how we obtained the charcoal for this review. Since we published our review of the 2007 Indonesia charcoal which produced a "Below Average" rating, Kamado has refused to sell us charcoal for our reviews. When readers contacted us asking us to do reviews of the newer Kamado coconut charcoals, we could only reply that Kamado refused to sell us samples for testing. As a result, several of our readers volunteered to purchase charcoal from Kamado and forward it to us for testing and review. Each box of charcoal obtained in this manner has arrived at our doorstep sealed and in good condition. There is no reason to believe that the charcoal we received from our readers is in any way different than charcoal we might have received had Kamado been willing to ship it direct to us.
So, let's now take a look at the Kamado 2009 Indonesian coconut charcoal and see how it did.
The Charcoal -- Packaging, Condition, Appearance
As you can see in the photo above, even though the box appeared to have arrived undamaged, there was a significant amount of broken briquettes in the box. The charcoal itself appears to be relatively fragile, not a good sign of quality charcoal. We were able to crush broken pieces of the charcoal between our thumb and forefinger. If we rubbed the side of the briquette with our thumb, powder rubbed off. The briquettes actually feel somewhat soft in your hand.
Another indication of the hardness or softness of this charcoal is the fact that simply touching one of these briquettes leaves a significant amount of black powder on your hands. The 2003 briquettes were hard and left virtually no residue on your hands.
Although the box is labeled as containing 16.5 pounds, as you can see in the following table, the box actually contains 20 pounds. (We sorted the box into whole pieces, broken pieces, and fines which were unusable.) Here are the results:
You might be tempted into thinking that you got a bargain, getting 20 pounds of charcoal while the box says 16.5 pounds. Perhaps this is done to compensate for the large amount of crushed charcoal in the bottom of the box? No, we have only to look to the Kamado forum to find this post by Richard Johnson:
81% of the box is comprised of whole pieces, 13% of the box is broken pieces that you might consider tossing into the fire, and 6 percent is essentially unusable. While the 6% unusable chips and dust would fall into the "Low" category for lump charcoals, the 2003 Philippine charcoal arrived with no broken pieces and only a miniscule amount of dust in the bottom of the box. To compare, the box of this charcoal contained 554 grams of dust and chips. The box of 2003 extruded coconut that we opened most recently contained only 10 grams of dust. (10 grams is approximately 1/3 of an ounce versus the one and a quarter pounds of dust in this box.) This charcoal is much more fragile and subject to breaking than the 2003 charcoal.
How hard was it to break the 2003 Philippine charcoal in half? We couldn't do it bare-handed. You might as well try to imagine trying to break a steel rod in half.
Indeed, we found we could easily break a piece of this 2009 charcoal in half with our bare hands,
and even into quarters with a little more effort. On the other hand, we couldn't begin to break one of the 2003 pieces using our hands. We also improvised a little hammer test back in 2007 in which we allowed the head of a standard claw hammer fall about 6 inches onto a piece of each charcoal. Similar to what we found in 2007, a piece of this charcoal shattered on the first impact. The piece of 2003 charcoal wasn't even dented after 3 impacts. We had to swing the hammer with moderate force in order to shatter it.
In addition, we suppose it doesn't help that the boxes used for this 2009 charcoal appear to be the same boxes used on the 2007 Indonesian charcoal. These boxes are less substantial than the boxes used for the 2003 charcoal. The 2003 boxes were quite sturdy and had capacity and strength data printed on the bottom. These new boxes are flimsy and have no such data printed on them.
What about the physical appearance of the briquettes? Many of the Indonesian briquettes from 2007 were crooked, cracked, mis-shapen, bringing into question whether or not the briquettes were actually extruded. The 2007 Try-It-Yourself briquettes were also cracked and mis-shapen. These 2009 briquettes are no better, as you can see in the photos below:
Needless to say, the 2003 briquettes were hard, not cracked and rarely had any crumbling on the ends.
Burn Time
Furthermore, if you look at the cost of this charcoal per hour of burn time, it costs about $0.07 per hour to burn a pound of this charcoal, if of course you exclude shipping charges. That makes it about average compared to the 92 we have tested so far. Most quality charcoals cost less than $0.05 per hour per pound to burn, so this charcoal is no bargain. And of course, if you include shipping charges, the price per hour per pound of this charcoal skyrockets to over double the most expensive lump charcoals we have ever tested. Even with pallet shipping prices it is more expensive than any other lump charcoal to burn.
Ash Production
Each time we review a Kamado coconut charcoal product that produces such incredible amounts of ash, we get reports of a few individuals claiming that it produces very little ash. They claim that the ash production of these products is no worse than the 2003 Philippine coconut charcoal, or that it is no worse than Royal Oak lump charcoal. Even this latest 2009 charcoal from Kamado has produced a statement from an individual on the Kamado forum, saying (we quote) "Good stuff, light ash production..." Such statements beggar belief if you have actually burned both types of charcoal, so this time, we thought we would produce a short video which demonstrates exactly how bad the ash production of this newest coconut charcoal briquette really is. Samples of the 2003 Philippine charcoal and this new 2009 Indonesian charcoal were burned side-by-side, at the same time, in the same location, under the same conditions. As you will see in the video, the Indonesian charcoal produces over 4 times more ash by volume and 12 times more ash by weight than the 2003 Philippine charcoal.
(If you watch the video, you find that the Philippine charcoal ash plus pan weighed 15 grams and the Indonesian charcoal ash plus pan weighed 109 grams. When we subtracted the weight of the pans to get the actual weight of the ash (we weighed the pans prior to starting the experiment), the Philippine ash weighed 8 grams and Indonesian ash weighed 103 grams. So, the Indonesian ash weighs over 12 times what the Philippine ash weighs! The volume of ash shown in the video was 75ml for the Philippine and 350ml for the Indonesian, meaning the Indonesian charcoal produces over 4.5 times the volume of ash that the Philippine charcoal produces!)
This ash production problem becomes even more apparent when you look at the volume of ash produced per hour of burn time. Because of the double whammy of high ash production and low burn time, this charcoal produces the third highest amount of ash per hour, exceeded only by the 2007 Try-It-Yourself Kamado charcoal and the 2006 Thailand Kamado charcoal. There is just no other way to say it; the ash production is truly staggering. The following photos show the enormous amount of ash produced by only three of these charcoal briquettes:
Now try to imagine the quantity of ash that would be produced by a cooker filled with these briquettes for an overnight cook. Truly jaw-dropping. We were barely able to keep our large Big Green Egg cooker going for an overnight cook with the 2007 Indonesian charcoal before the ash completely blocked the airflow. With this charcoal producing roughly 25% more ash, it would not be usable for long overnight cooks in many types of ceramic cookers.
Before we leave the topic of ash production we'd like once again to dispel the notion that perhaps we just got a bad batch. One Kamado customer posted on the Kamado discussion board that the ash content depends on how the raw material was carbonized. His statement implied that the high ash production of our sample of Kamado coconut briquettes was due to poor manufacturing, i.e., it is just a "bad batch". To
This is simply not true. Ash is mineral matter, such as clay, silica and calcium and magnesium oxides, both present in the original raw material (wood or coconut shell) and picked up as contamination from the earth during processing. At the time that the wood is cut or the coconut shell is harvested, it contains a certain amount of ash. This original amount of ash will be left after combustion whether you burn the wood/coconut shell down to ash, or convert the wood/coconut shell to charcoal and then burn the charcoal down to ash. If the raw material is not properly carbonized, then the finished product will contain more of the volatile organic compounds that are normally driven off in the carbonization process. However, the final product will still contain exactly the same amount of ash as if the raw material had been properly carbonized.
In other words, carbonization does not remove ash from the wood or the coconut shells during the process of converting it to charcoal. Hence, the ash content of charcoal has very little to do with the process used to make the charcoal unless you contaminate the source material or deliberately add some other materials to it. So, we didn't just get a "bad batch." We got charcoal that's just like everyone else got and our results are representative of what everyone will see.
Since the ash produced by this charcoal is so staggering, we have measured the ash content of the charcoal in addition to the volume of ash produced when it burns in a cooker. Ash content can be determined by heating a weighed sample to red heat in the presence of air to burn away all combustible matter. The residue left behind is the ash. (In other words, you burn the charcoal and weigh the resulting ash.) You then merely calculate what percentage the weight of the ash is of the weight of the original sample. So, to calculate the ash content of this new charcoal, first we heated our charcoal sample in an oven for several hours to drive off the moisture. We checked the weight of the sample periodically and stopped when the weight stabilized. We then burned the charcoal inside of a large cooker with plenty of airflow and allowed the sample to burn completely to ash. We then weighed the remaining ash and calculated the ash content of the original sample.
So what is the ash content of this latest Kamado extruded coconut charcoal? It was a staggering 33.8%, almost a new record. Here is a table showing the ash content of each type of Kamado coconut charcoal we have tested:
What does all this mean? Well, the Food and Agriculture Organization of the United Nations report "Simple Technologies For Charcoal Making" indicates that pure coconut charcoal contains about 1.5% ash. A survey of several coconut charcoal manufacturers reveals claims of ash content in the 1.8-5.0% range for their products. Clearly, all of these various types of Kamado coconut charcoal except for the 2003 Philippine variety have massive quantities of binder/filler added to them. Why would manufacturers do this? Our research has indicated that when a buyer contracts to purchase coconut briquettes, they can specify the amount of filler included in order to affect the price. More filler equals a lower price. (We'll address this in a bit more detail down below in the section "Additives and/or Fillers".)
One final note. When we did our review of the 2007 Indonesian coconut briquettes, we did side by side comparisons of ash produced by various types of charcoal. This included different types of Kamado coconut charcoal as well as Royal Oak lump charcoal. If you would like to see those side by side comparisons, click here. You will be taken to the portion of the 2007 Indonesian review which disproved the many claims that the 2007 Indonesian charcoal didn't produce any more ash than other charcoals. When you view those side by side photographs, just imagine this charcoal producing roughly 25% more ash than the 2007 Indonesian briquettes.)
Moisture Content
We witnessed the effect of this elevated moisture content, as you will read below, in our maximum temperature test. When snuffing the fire, moisture condensed on the lid and then dripped into the fire. Most charcoals we have tested don't do this.
Lighting The Charcoal
Maximum Temperature
For this 2009 Indonesian Kamado coconut charcoal, we were only able to get our cooker to 720 degrees. We have run this test on dozens of brands of lump and extruded coconut charcoals, and 720 degrees ranks "low" on the range of temperatures that we have measured. Obviously, this is not "50% hotter" than any other brand of charcoal we have ever measured. We attribute this unusually tepid result partially to the elevated moisture content of the charcoal. After we are done measuring the maximum temperature of a charcoal, we place the ceramic lid back on the cooker to snuff the fire. After a minute or so, you can check the underside of the lid for condensation and sure enough we found enough condensation on the lid to be dripping off the lid down into the cooker. Also, of course, we have to think that the fact that this charcoal evidently contains a large amount of filler (see section below) contributes to its inability to burn hot.
On the other hand, if you interpret this statement to mean that the temperature of combustion measured right down in the burning charcoal is "50% hotter" than other charcoals, we can measure that also. Although it is hard to imagine a charcoal that can't produce top temperatures in the cooking chamber could be actually burning at a higher temperature than other charcoals, we have the ability to measure it so let's look. Whereas this is not a test that we routinely run, we have run it against Kingsford briquettes and Royal Oak American hardwood charcoal. Kingsford is, of course, your "typical store-bought briquettes", and Royal Oak American hardwood charcoal is a very good brand of lump charcoal.
So, how did we measure the temperature of burning charcoal down in the actual region of combustion? We simply piled up some charcoal in our medium Big Green Egg ceramic charcoal cooker and then used a Thermoworks WD-08467-64 High Temperature Ceramic Fiber Insulated Probe inserted into the burning charcoal in the heart of the fire. This probe is capable of measuring temperatures up to 2500 degrees F. Here are the results we obtained:
So once again, the 2009 Kamado coconut charcoal does not burn "50% hotter" than other charcoals, whichever definition of "burns hotter" you wish to use. In fact, it burns at a much lower temperature than your average charcoal when measured in the cooking area of a ceramic cooker.
One additional observation we made in our past reviews of some of the Kamado coconut charcoals was that the charcoal became very fragile after burning. In fact, after our maximum temperature test, we allowed the charcoal to cool and then we tried to stir the charcoal to knock the ash off for the next burn. What we found was that most of the charcoal briquettes crumbled to powder and thus were unusable. This 2009 Indonesian charcoal appears not to suffer from this fault. After our maximum temperature test was run and the charcoal cooled, we were able to stir it up and knock off the ash without destroying all the remaining charcoal. If you are reasonably gentle in your stirring, you can preserve a large portion of the leftover charcoal for your next fire. A small consolation to offset the poor burn time, perhaps.
Smoke, Odor and Food Flavor
Completely odorless? Not all all. Burning quality coconut charcoal like the 2003 Philippine coconut charcoal produces a relatively strong, sweet and pleasant odor until, like most charcoal, it is completely ignited and burning hot. Then, like most charcoal, there is less odor. During our test burn to determine the burn time of this charcoal, we could smell the charcoal burning during the entire burn. This new charcoal which is loaded with some sort of filler (see section below) does not have the characteristic sweet odor of quality coconut charcoal. While the smoke vaguely resembles the smell of coconut charcoal, when this charcoal burns it also reminds us of cigar smoke. Essentially, it smells like a cross between a hint of the coconut charcoal smell you would expect and a burning cigar. We can only attribute that to the presence of the filler/binder that this charcoal is loaded with.
As for a taste test, we again cooked some chicken tenderloins over some Royal Oak lump charcoal and over this 2009 coconut charcoal. The flavor was pretty mild with just a hint of an off-flavor. When we did this test using the 2003 Philippine charcoal, the chicken took on a stronger and more pleasant flavor. However, the flavor was so mild that we doubt that you would taste it if you are using rubs and sauces on your meat and smoking woods to add smoke flavor.
Use For Grilling
So, it is pretty clear that this charcoal would not be ideal for grilling, and is probably best left for low-temperature smoking. Of course, this is entirely in line with our maximum temperature testing results.
Additives and/or Fillers
In fact, our research into the manufacturing of coconut charcoal briquettes yielded information from a distributor in Indonesia indicating that the molding process required more binder than the extruding process and thus more ash was the result. While we don't have confirmation that these briquettes were actually molded or extruded, we have also received information about a common practice in the coconut charcoal industry in Southeast Asia. A coconut charcoal manufacturer explained that if the customer wants a lower-priced product, manufacturers will simply add filler to the coconut charcoal before molding/extruding. Filler is cheaper than coconut charcoal and this filler, of course, replaces the carbon content of the carbonized coconut shells. This results in a cheaper product with higher ash content and reduced burn times. See the following table that contains results of our testing from the five reviews. More ash content roughly equals less burn time:
This explains the wide variation in ash production and burn times between the different types of coconut briquettes that Kamado has sold. The different manufacturers who have been supplying Kamado with coconut briquettes have apparently been adding various amounts of filler to their products, despite Kamado's claims that their coconut briquettes contain no filler. It may also explain how Kamado was able to reduce the price of their charcoal from $11.99 for 16.5 pounds ($0.72/pound) in 2003 for the high-quality Philippine charcoal to $8.99 for 20 pounds ($0.45/pound) in 2009 for their current charcoal.
Compared To Traditional Briquettes
As you can see, Wicked Good Charcoal Weekend Warrior Briquettes wins in every category. If you want slow steady burning for overnight cooking, which is probably what most folks would agree is what Kamado coconut charcoal is intended for, it would seem that Wicked Good Charcoal briquettes would be a better choice. They are cheaper, you can call the company and get an answer, you can get the briquettes shipped in a few days, and the briquettes perform better in every category.
There are also a number of "all-natural" briquettes available in stores (Royal Oak, Nature's Grilling, Stubbs, Picnic) which you may also wish to investigate. With no shipping to pay, these charcoals can be purchased for 1/3 the cost of the Kamado coconut briquettes.
Purchasing
Then there is the matter of getting your order placed to begin with and then shipped.
The Kamado forum abounds with posts from customers over the years asking for help in getting Kamado to respond to their requests to purchase charcoal and accessories for their cookers. There are also posts asking for status on paid orders, sometimes months after the orders had been placed. It is hard to know how long it takes to get charcoal shipped, but the sample we obtained was indeed difficult to obtain.
The person who provided us with the sample for our review kept a log of all the calls and emails that were sent. This was their account of getting the order placed and shipped:
And then there is the matter of paying for the charcoal. Kamado does not accept credit cards for some reason. Should you encounter any difficulty with your order, you would not have the protection that paying by credit card affords.
