How Much Charcoal Do I Need for a Braai? A Practical NZ Guide

How much charcoal do you need for a braai? The useful answer is: enough to create the heat zone and cooking time your food needs — not automatically a full bag or even a full chimney. For a quick direct cook you may need only a modest, concentrated bed of charcoal; a large family braai or long indirect cook needs more fuel. Your cooker size, fuel type, airflow, weather and cooking method all change the answer.

That is why counting exact pieces of charcoal is rarely the best approach, especially with irregular hardwood lump charcoal. A more repeatable method is to use a charcoal chimney as a measuring cup and learn what a quarter, half and full chimney does in your own braai or kettle.

How much charcoal should I use?

Start with the cooking method, not the number of people. A few steaks cooked very hot can require a stronger fire than a larger quantity of sausages cooked at moderate heat. As a practical starting point for a standard kettle-style grill, think in chimney fractions rather than kilograms or individual lumps.

Type of cook	Practical starting point	Fire setup
Small quick cook	About 1/3 to 1/2 chimney	Concentrated direct zone
Everyday braai	About 1/2 to 3/4 chimney	Two-zone fire
High-heat searing	About 3/4 to 1 full chimney	Concentrated hot zone
Indirect roasting	About 1/2 to 1 chimney to establish the fire, then manage or replenish as needed	Charcoal banked away from the food
Low and slow	Use a controlled amount of lit fuel to progressively ignite unlit fuel	Snake, baskets or another cooker-appropriate indirect setup

These are starting points, not universal measurements. Chimney sizes vary, lump charcoal pieces are irregular and every cooker behaves differently. Always follow your barbecue manufacturer's fuel limits and instructions.

Why is there no single correct amount of charcoal?

Charcoal quantity depends on what you are cooking, how hot you want the fire and how long it needs to run. Weber's own guidance says the amount of charcoal should be selected according to the food and barbecue size, with different quantities for direct and indirect cooking.

There are several variables at work:

• Cooker size: a compact portable braai needs less fuel than a 57 cm kettle or a large open grill.
• Fuel type: lump charcoal and briquettes do not burn in exactly the same way.
• Airflow: more oxygen generally means a hotter, faster-burning fire.
• Weather: cold conditions and wind can increase heat loss or change combustion.
• Lid use: a covered kettle can retain heat differently from an open braai.
• Food: a thin steak, chicken pieces and a large roast all need different fire strategies.

How much lump charcoal do I need for steak?

For steak, focus on creating a concentrated high-heat zone rather than covering the entire charcoal grate. In a standard kettle, roughly half to a full chimney of lump charcoal can be a sensible starting range depending on how many steaks you are cooking and how large the grill is.

Lump charcoal is particularly useful here because it lights readily, can reach strong searing heat and responds quickly to airflow. Bank the coals together so the radiant heat is concentrated. If the steaks are thick, leave a cooler zone available so you can move them away from the strongest heat to finish cooking.

Using more charcoal than you need across the whole grill often wastes fuel without improving the result.

How much charcoal do I need for boerewors?

Boerewors usually benefits from a moderate, controllable fire rather than the most aggressive heat your charcoal can produce. For a normal family cook on a kettle, around half a chimney is often a useful place to start, arranged so that you have both direct and cooler cooking areas.

The two-zone setup is valuable because rendered fat can cause flare-ups. If that happens, move the wors temporarily to the cooler side rather than fighting flames directly underneath it.

How much charcoal do I need for chicken?

For chicken pieces, build enough charcoal for a two-zone fire and do much of the cooking away from the strongest direct heat. Around half to three-quarters of a chimney can be a reasonable starting point for a standard kettle, but the amount should be adjusted for cooker size and cooking time.

Indirect heat gives you time to cook chicken through without excessively darkening the outside. Direct heat can then be used deliberately for browning and crisping.

How much charcoal do I need for burgers, chops and kebabs?

For a short cook of burgers, chops or kebabs, you normally need a compact hot fire rather than a huge fuel load. Roughly one-third to two-thirds of a chimney may be enough for a modest batch, depending on the size of your cooker and how intensely you want to grill.

If you are cooking in several batches for a crowd, start with a stronger fuel bed and keep some additional charcoal available rather than spreading a small amount too thinly.

Should I use a full chimney of charcoal?

A full chimney is useful when you need a large, hot fire, but it should not be the automatic setting for every cook. Current grilling guides and community discussions repeatedly raise the same problem: cooks light a full chimney for a small meal, then finish the food while a large amount of usable charcoal is still burning.

For a couple of steaks or a small weekday braai, try less fuel and concentrate it. For a large cook, high-heat sear or bigger kettle, a full chimney may be completely appropriate.

How do I measure lump charcoal when every piece is different?

Measure lump charcoal by volume rather than counting individual pieces. A chimney starter is useful because it gives you a repeatable reference: quarter, half, three-quarter or full.

This is more practical than saying “use 40 pieces” because natural lump varies greatly in shape and size. Even two bags of good hardwood lump charcoal will not contain identical pieces.

Weber also supplies charcoal measuring guidance with some kettle models and distinguishes between quantities for lump charcoal and briquettes. The important lesson is the method: use a repeatable volume measure, then refine it for your own cooker.

Lump charcoal or briquettes: does the amount change?

Yes, because lump charcoal and briquettes behave differently. Lump is irregular and typically responds quickly to airflow, making it excellent for hot, responsive fires. Briquettes are uniform, which can make them easier to measure and useful when a long, steady fire is the priority.

If you are deciding which fuel suits a particular cook, see our Lump Charcoal vs Briquettes: How to Choose guide. For a deeper introduction to lump, read Lump Charcoal: The Complete Guide to Better Braai & Grilling.

How much charcoal do I need for low-and-slow cooking?

For low-and-slow cooking, the goal is not to light a huge amount of charcoal at once. Instead, established methods use a smaller ignition point that progressively lights additional fuel over time.

In a kettle, that might mean a snake-style arrangement of briquettes or charcoal baskets configured for indirect cooking. In a kamado, a larger bed of unlit lump charcoal can be lit at a single point and controlled with restricted airflow. The correct setup varies by cooker, so follow its manufacturer's guidance.

This is also one situation where Safari Wood Briquettes 4kg may be the easier fuel to manage because their uniform size helps with repeatability.

Can using less charcoal actually make cooking easier?

Yes. An oversized fire can make temperature control unnecessarily difficult. More fuel does not automatically produce better food. If the fire is much hotter than the cook requires, you end up trying to restrict it aggressively or moving food constantly to prevent burning.

Start with a sensible amount for the job. You can add fuel when required, but you cannot instantly remove the heat stored in a large bed of fully lit charcoal.

How do I make my charcoal go further?

Use a defined heat zone, control airflow and extinguish reusable charcoal when the cook is finished. These three habits can reduce waste significantly.

• Do not automatically cover the whole charcoal grate.
• Use a two-zone fire so intense heat exists only where you need it.
• Keep the grill lid closed when the cooking method calls for it.
• Make gradual vent adjustments rather than leaving maximum airflow throughout the cook.
• On a suitable covered cooker, close the vents after cooking to extinguish the fire according to the manufacturer's instructions.
• Once completely cold and dry, solid partially burned charcoal can often be reused.

What if I run out of heat halfway through?

Add more fuel before the fire collapses completely. Lump charcoal catches relatively quickly, while briquettes generally take longer to establish. If you know a cook will be lengthy, plan the fire so additional fuel can be introduced safely or use a progressive-burning method from the beginning.

Do not make three changes at once. Add fuel, give the cooker time to respond, then adjust airflow if necessary. This makes it much easier to learn what actually changed the temperature.

A simple charcoal rule for New Zealand braais

Use the smallest fire that comfortably gives you the heat and cooking time you need, with a little reserve for unexpected delays. That is more useful than treating every braai as a full-chimney event.

For quick high-heat grilling, Safari Hardwood Lump Charcoal 4kg is a natural fit. For longer, steadier sessions, Safari Wood Briquettes can be a practical alternative. Neither fuel is automatically right for every cook — choose according to the job.

Frequently asked questions

How much charcoal do I need for two steaks?

You usually do not need to fill an entire kettle. Create a compact high-heat zone with roughly one-third to half a chimney as a starting point, then adjust for steak thickness, grill size and desired heat.

How much charcoal do I need for four people?

There is no reliable amount based only on headcount. Four steaks require a different fire from a whole chicken or a long roast. For an ordinary mixed braai on a standard kettle, roughly half to three-quarters of a chimney is a useful starting range.

How much charcoal should I put in a Weber kettle?

It depends on kettle size and whether you are cooking directly or indirectly. Weber publishes model-specific charcoal quantities, so use those instructions as the baseline for your barbecue and then adjust based on your experience.

Can I add unlit charcoal to lit charcoal?

Yes, where your cooker and cooking method allow it. This is a normal part of several long-cook techniques. Add fuel carefully and allow the fire to stabilise before making further adjustments.

Is it better to use too much charcoal or too little?

For everyday grilling, aim for enough fuel with a modest reserve rather than deliberately oversizing the fire. Too little can be topped up; too much fully lit charcoal can create unnecessary heat and fuel waste.

How long should charcoal last?

There is no universal burn time. Fuel type, piece size, cooker efficiency, airflow, weather and the amount of charcoal burning at once all affect duration. Treat advertised burn times as guides rather than guarantees.
