By selecting the best coffee roasting methods, you can guarantee the quality and uniqueness of your brew. In this article, we explore the 10 best roasting methods for your mobile coffee business.

Air roasting

Also known as fluid bed roasting, air roasting is a method that utilises hot air to agitate and roast coffee beans.

The process

In air roasting, the coffee beans are placed in a roasting chamber where hot air is pushed through, causing the beans to levitate and roast evenly. This method allows for precise temperature control, which in turn influences the flavour profile of the coffee.


Air roasting is known for its clean, vibrant flavours. It's also a quick process, typically taking less than 10 minutes, making it ideal for a mobile coffee business where speed and efficiency are crucial.

Drum roasting

Drum coffee roasting is a traditional and popular method used by many coffee roasters.

The process

The drum, which is a horizontal rotating cylinder, is heated, and the coffee beans are added. As the drum rotates, the beans are roasted evenly due to the constant agitation.


Drum roasting allows for a deeper roast, perfect for creating rich and bold flavours. It's also ideal for roasting large batches of coffee, making it a suitable choice for a mobile coffee business serving a high volume of customers.

Popcorn maker roasting

Yes, you read that right! A popcorn maker can double up as a coffee roaster. This is an unconventional, yet effective method for small-scale roasting.

The process

Just like popcorn, coffee beans are added to the popcorn maker. The hot air circulates, roasting the coffee beans evenly.


This method is cost-effective, easy to use, and portable, making it a practical choice for a mobile coffee business on a budget.

Pan roasting

Pan roasting is a traditional method that's been used for centuries. It's simple yet effective.

The process

Coffee beans are roasted in a pan over a heat source. The raw coffee beans must be stirred constantly to ensure an even roast.


Pan roasting is a low-cost method that requires minimal equipment. It's also a quick process, allowing you to roast beans on-demand, ensuring maximum freshness.

Oven roasting

Oven roasting is another straightforward method that can be used for coffee roasting.

The process

Unroasted coffee beans are spread out on a baking tray and placed in a preheated oven. The beans are then roasted to the desired level.


Oven roasting is a convenient method as most mobile coffee businesses will already have an oven. It also allows for larger batches of raw coffee beans to be roasted at once.

Hot top roasting

Hot top roasting is a method that utilises a machine specifically designed for home coffee roasting.

The process

The coffee beans are added to the machine, and the roast is controlled using a digital interface.


Hot top roasting machines offer precise control over the roasting process, allowing you to achieve consistent results every time.

Stovetop roasting

Stovetop roasting is a method that utilises a stovetop popcorn popper to roast coffee beans.

The process

Coffee beans are added to the popcorn popper and placed on a stovetop. The beans are then agitated by turning the handle, ensuring an even roast.


Stovetop roasting is a cost-effective method that offers a high degree of control over the roasting process.

Smokeless roasting

Smokeless roasting is a method designed to minimise the smoke produced during the roasting process.

The process

Specialised smokeless roasting machines use a catalytic converter to reduce smoke emissions.


Smokeless roasting is an environmentally friendly method that's also ideal for indoor roasting, making it a suitable choice for mobile coffee businesses operating from a van or small space.

Solar roasting

Solar roasting is a new and innovative method that utilises solar energy to roast coffee beans.

The process

Solar roasting machines use solar panels to generate heat, which is then used to roast the coffee beans.


Solar roasting is a sustainable and environmentally friendly method. It also requires little to no electricity, making it an economical choice.

Instant roasting

Instant roasting is a method that utilises high-frequency heating to roast coffee beans in an instant.

The process

Instant roasting machines use high-frequency heating technology to roast coffee beans in less than a minute.


Instant roasting is a time-saving method that allows for on-demand roasting, ensuring maximum freshness and flavour.
