Choosing the right fuel is one of the most important decisions when cooking outdoors. Whether you are grilling a quick dinner or preparing a feast for friends and family, the fuel you use affects heat control, flavour, cooking versatility, and the overall experience.

The three most common fuels used in outdoor cooking are gas, hardwood, and charcoal. Each one has its place, but they deliver very different results.

Understanding the differences will help you decide which approach best suits the way you want to cook.

 

Gas BBQ: Convenient but Limited

Gas grills have become popular because they are easy to use. With the turn of a knob, you can start cooking in seconds and quickly control the temperature.

For many people, this convenience is appealing.

However, gas grills rely entirely on direct heat from burners, which means they lack one of the most important elements of traditional cooking: real fire and natural smoke flavour.

 

Limitations of Gas

While gas is convenient, it comes with trade-offs.

Because there are no burning embers or wood, gas grills cannot produce the natural smoky flavours that come from cooking over fire. They also limit the ways you can cook, as most gas grills are designed only for direct grilling.

Gas BBQs are great for quick meals, but they rarely deliver the depth of flavour or cooking versatility that comes from cooking with real fire.

 

Cooking With Wood: The Traditional Approach with Terra Grills Open Fire BBQ The Portico

Wood has been used for cooking for thousands of years, and for good reason. When hardwood burns, it creates hot, stable embers and aromatic smoke that enhances the flavour of food.

Cooking with wood allows you to control heat by adjusting the fire and the distance from the embers. It also allows multiple cooking styles at once, such as grilling, slow roasting, smoking, or hanging food over the flames.

Advantages of Cooking With Wood

• Natural smoky flavour

• High heat for searing

• Long-lasting embers

• Multiple cooking techniques

• Authentic fire cooking experience

Hardwoods such as ironbark, red gum, and oak are ideal because they burn steadily and produce consistent heat.

Beyond flavour, cooking with wood creates an atmosphere that gas simply cannot replicate. The fire becomes the centre of the gathering, bringing people together around the warmth and glow of the flames.

 

Cheap Charcoal: Fast but Not Always Ideal

Charcoal is another common fuel for BBQ cooking. However, it is important to distinguish between cheap charcoal briquettes and natural lump charcoal.

Many inexpensive briquettes are made using compressed charcoal dust mixed with binders, fillers, and additives. While they are widely available and easy to light, they can produce more ash and sometimes unwanted odours.

Characteristics of Cheap Charcoal

• Quick to ignite

• Inexpensive

• Consistent shape and size

 

But cheap charcoal also has several downsides:

• Often contains additives

• Produces more ash

• Can burn unevenly

• Less natural flavour

Because of this, many experienced fire cooks prefer natural lump charcoal, which is made from pure hardwood without additives. Lump charcoal burns hotter and cleaner and is often used alongside hardwood logs.

 

Flavour: The Biggest Difference

One of the main reasons people choose wood or charcoal over gas is flavour.

When fat and juices from food drip onto hot embers, they vaporise and rise back into the food as aromatic smoke. This creates the rich, complex flavour that people associate with traditional barbecue.

Gas grills cannot recreate this process because there are no real embers involved.

Cooking over wood or charcoal produces deeper flavour, subtle smokiness, and a more authentic result.

 

The Experience of Cooking Over Fire

Beyond flavour, the biggest difference between gas and fire cooking is the experience.

Gas grilling tends to be a solitary activity — one person stands behind the grill while everyone else waits.

Cooking over fire is different.

The fire naturally becomes a gathering point. People gather around the flames, talk, help cook, and share the moment. The process becomes part of the event, not just the preparation of food.

It transforms a simple meal into a shared experience.
