Lump Charcoal vs Briquettes: Which is Better for Your Grill?
Stand in front of the charcoal display and you're face with a choice: Lump Charcoal or Briquettes? After years of using both on everything from Big Green Egg's to Weber Kettles, I get this question constantly from customers at BBQ Republic.
The short answer: it depends on what you're cooking and what grill you own. By the end of this guide, you'll know exactly which one suits your setup.
What is Lump Charcoal
Lump charcoal is carbonized hardwood. Wood (ironbark, red gum, jarrah) burned in a low-oxygen kiln until only carbon remains. No additives, no fillers, no binders.
Its 100% natural hardwood in irregular shapes and sizes. Burns between 760 to 980°C, lights in 15-20 minutes, and produces minimal ash (around 5-10%). Highly responsive to airflow changes, which makes temperature control precise.
What Are Charcoal Briquettes?
Briquettes are compressed wood byproducts (Sawdust, wood chips) mixed with binding agents. They were invented in the 1920s by Henry Ford to use wood scraps from Model T Production.
Inside you'll find carbonized sawdust and and wood chips, binding agents like starch or cornstarch (sometimes Borax), and additives such as sodium nitrate and limestone in traditional brands. Some varieties even include lighter fluid.
They're uniform pillow-shaped blocks that burn at 425 to 540°C for over an hour. More predictable temperature but take 25 to 30 minutes to light. Produce significant ash (30-50%) and responds slowly to temperature adjustments.
The Direct Comparison
Lump charcoal is pure hardwood that lights quickly and burns hot. Maximum temperatures reach 760 to 980°C with minimal ash production. Burns for 30 to 60 minutes at high heat. Highly responsive to airflow. Costs $3 to $6 per kg. Clean, natural wood smoke. Best for kamados and high-heat searing.
Briquettes are wood byproducts with additives. Take longer to light but burn steadily at 425 to 540°C for 1 to 3 hours. Produce significant ash (30-50%). Slow temperature response. Uniform size. Cost $1.50 to $3 per kg. Can have chemical smell initially. Best for long smoking and steady temps.
Why Lump Charcoal Works Better
Pure carbonized wood. Nothing else. For anyone who prioritizes clean grilling, particularly Big Green Egg owners, this matters.
When I sear steaks at 370°C,+ on my Big Green Egg, lump gets me there fast.
Pro Tip: The Pyralit starter cuts lighting time nearly in half compared to traditional chimney starters. Engineered airflow gets lump charcoal ready in around 10 minutes. No lighter fluid needed, just smarter design.
Lump produces so little ash I can do 3 to 4 cooks before cleaning out my kamado. With Briquettes, i'd dump ash after every cook. This is critical for kamado owners. Briquette ash overwhelms the small collection system, blocking airflow and causing temperature drops or flame-outs.
Open the vents with lump charcoal and temperatures start to climb within minutes. Close them and it drops quickly. Precision control that briquettes can't match.
Close all vents after cooking, let the fire die, and the next day partially burned lump is ready to reuse. Shake off the ash with a charcoal basket, add some more fresh lump, done. I've reused lump 2 to 3 times on countless cooks.
The Tradeoffs with Lump
High heat means faster burn. For a 12-hour brisket smoke, you'll refuel multiple times. Briquettes cruise through with minimal attention.
Large chunks, medium pieces, small bits, dust, Irregular shapes make stacking difficult and can create airflow issues if small pieces nest together.
Quality lump runs $3 to $6 per kg vs. $1.50 to $3 for briquettes. For frequent cooks, this adds up. However, lump produces less waste, is reusable, and you use less per cook. The actual cost gap is smaller than it appears.
Lower-Quality lump can spark. Not usually a problem in closed kamados, but startling on open grills.
Why Briquettes Still Exist
For weekly cooks, briquettes offer better upfront value. Significant cost savings compared to premium lump.
Smoking ribs for 5 hours or pork for 12? Briquettes maintain steady temps with less monitoring. Load your grill, set vents, walk away. This predictability is why some competition pitmasters still use briquettes for low-and-slow.
The "snake method" (coals arranged in a line that burns progressively) or the "minion method" (adding lit coals to unlit) work beautifully with uniform briquettes. Irregular lump makes these harder.
The Problems with Briquettes
Traditional briquettes contain binders (starch, borax), fillers and additives. (Sodium nitrate, limestone). During lighting, these produce a chemical smell and off-coloured smoke. Many report this affects delicate foods like chicken or fish.
Briquettes produce 30 to 50% ash by volume. Frequent dumping, more cleanup, potential airflow issues. On my Weber kettle, i'd see ash coating foil-wrapped food.
Once burning, briquettes are committed. Opening vents doesn't raise the temp quickly. Closing them doesn't drop it fast either. Load too many or too few and you're stuck with that temperature.
Consistent burn requires more ignition time. Expect 25 to 30 minutes vs 15 to 20 for lump.
Which Charcoal Should You Use?
After years of testing both across kamados & kettle grills, here's my honest recommendation:
Why I stock (and Recommend) Lump Charcoal
For Kamado Owners (Big Green Egg, Kamado Joe etc):
This isn't even a debate. Lump charcoal is essential. The minimal ash production is critical for kamado airflow. Briquette ash will clog your fire grate, restrict airflow, and cause temperature issues or even flame-outs. Every kamado manufacturer specifically recommends lump for good reason.
For Serious Grillers:
If you've invested in quality equipment and care about what you're cooking, lump is the clear choice. All-natural hardwood, no chemicals, clean smoke, responsive temperature control. Its what serious cooks use.
For High-Heat Cooking:
Steaks, burgers, anything that needs searing tempts above 320°C. Lump is the only option. Briquettes simply can't reach these temperatures.
When Briquettes Make Sense (And Why We Don't Stock Them).
Briquettes have one real advantage: They're cheaper and burn longer. For casual backyard grillers doing occasional low-and-slow cooks on basic equipment, briquettes work fine. But here's why we focus on lump:
Our customers own quality grills.
If you've invested in a Big Green Egg, Kamado Joe, or other premium BBQ's you deserve premium fuel. Using briquettes in a kamado is like putting regular unleaded in a sports car. Technically possible, but why would you?
Briquettes compromise quality.
Chemical additives, excessive ash, slower response times. These aren't problems worth having just to save a few dollars per cook.
Lump is more cost-effective than it appears.
Yeas, $3 to $6 per kg vs. $1.50 to $3 for briquettes. But lump is reusable, produces minimal waste, burns hotter (so you use less), and doesn't require constant ash cleanup. The real cost difference is smaller than you think.
Our Recommendation:
Kamado owners: Lump charcoal. Non-negotiable.
Quality grill owners: Lump charcoal. You've invested in good equipment, use good fuel.
High-heat cooking: Lump charcoal. Only option for proper searing.
Anyone who values natural, chemical-free cooking: Lump charcoal.
Long smoking sessions: Premium lump works great. Load more at the start or refuel once mid-cook. Not difficult.
The Brands We Stock (And Why)
We carry premium lump charcoal because that's what our customers grills deserve.
After testing dozens of lump charcoal brands on my own grills, these consistently deliver: Minimal dust and small pieces, reliable ignition, clean burn, low ash production, and genuine hardwood quality.
We don't stock cheap lump or briquettes. Our customers own quality grills. They deserve quality fuel. The performance difference between premium lump and budget options is significant. Inconsistent piece sizes, excessive dust, poor burn characteristics, higher ash production.
Common Questions
But briquettes are so much cheaper. Isn't lump a waste of money?
Initially cost is higher, yes. But consider: Lump is reusable (shake off the ash, add some fresh charcoal and go again). You use less per cook due to the higher heat output. No constant ash dumping and cleanup. Better temperature control means less wasted charcoal from overshooting temps. One ruined brisket from temperature problems cost more than a year of premium lump.
For the quality of cook you get, lump is worth every dollar.
Can I use briquettes in my Big Green Egg?
Technically yes, but please don't. The ash production will clog your fire grate and create constant problems. Every Big Green Egg owner I know who tried briquettes switched back to lump within a few cooks.
Kamadoes are designed for lump charcoal. Use what they're designed for.
What if i'm just doing a simple cook and don't want to "waste" premium lump?
This is where reusable lump really shines. After a quick burger cook, close your vents. Next day, you've got partially burned lump ready to go. Add a bit of fresh lump on top, light it up and your done. You're not wasting anything.
I do quick weeknight cooks on reused lump all the time.
Where can I buy briquettes if I want to try them?
We focus exclusively on premium lump charcoal because that's what quality grills need. If you want to try briquettes, they're available at hardware stores (Bunnings etc) and major supermarkets.
After you experience the ash production, chemical smell, and temperature control issues, we'll be here with premium lump that your grill deserves.
How much charcoal do I need?
High-heat grilling (200 to 370°C: Full chimney equals. 1.5 to 2kg lump. Medium-heat grilling (180 to 200°C): Half chimney equalis 1Kg lump. Low-and-slow smoking (110 to 135°C): Quarter chimney lit, add unlit as needed.
Kamados use far less charcoal than traditional grills due to efficient ceramic walls.
My setup
I exclusively use lump charcoal on my Big Green Egg. I generally rotate between Big Green Egg's Natural Lump Charcoal and Argie Grillz depending on what I am doing.
After years of testing both lump and briquettes across different grill types, I made a clear choice: lump only. The performance difference is too significant. Better temperature control, cleaner smoke, minimal ash, no chemicals.
For kamadoes specifically, briquettes create more problems than they solve. The ash issue alone makes them a poor choice.
The Bottom Line
While briquettes exist and some casual grillers use them, they're not what serious cooks should be using.
Lump charcoal is superior for kamado grills (essential, definitely not optional), high-heat searing, temperature control and responsiveness, clean natural smoke flavour, minimal cleanup and ash production, and not to mention the quality cooking results.
Briquettes make sense for absolute budget priority on basic equipment and casual, infrequent grilling.
If you own a Big Green Egg, Kamado Joe, or even a quality Weber, you've already invested in great equipment. Use great fuel. That's why we stock premium lump exclusively.
