What is Air Roasted Coffee?

Air-roasted coffee is a unique method of roasting coffee beans that has gained popularity in recent years. Unlike traditional drum roasting, air roasting uses hot air to roast the beans, rather than a heated surface. The process involves heating the beans in a fluidized bed, where they are suspended and evenly roasted from all sides. The use of hot air allows for precise temperature control, which is important for achieving consistent and high-quality roasts. 

The result is a coffee that has a cleaner taste, brighter acidity, and a more distinct flavor profile compared to other roasting methods. Additionally, air-roasted coffee tends to have a lower acidity level and higher caffeine content compared to other roast types. Overall, air roasting is a preferred method for coffee aficionados who value the nuances and complexities of specialty coffee.

The History of Air-Roasted Coffee

Air roasting is a relatively new method of roasting coffee, with its history tracing back only to the 1990s. The process was developed by Michael Sivetz, a chemical engineer, who sought to create a roasting method that would be more efficient and produce higher-quality coffee. Prior to the invention of air-roasting, coffee beans were typically roasted in a rotating drum over an open flame or in a hot-air convection oven. 

Sivetz’s process involved using a fluidized bed of hot air to suspend the beans and roast them evenly, resulting in a more consistent and flavorful roast. Today, air-roasting has become increasingly popular among specialty coffee roasters, who value the method for its precision, efficiency, and ability to bring out the unique flavors and characteristics of different coffee varieties.

The Air Roasting Process

  1. Preheat your air roaster

Turn on your air roaster and preheat it to the desired temperature, usually around 375°F to 450°F depending on the type of beans and roast level you want to achieve.

  1. Weigh and measure your beans

Weigh out the number of green coffee beans you want to roast and pour them into the air roaster. Depending on the size of your air roaster, you can usually roast between 4 to 12 ounces of coffee beans at a time.

  1. Start the roasting process

Once the beans are loaded into the air roaster, set the timer and start the roasting process. The beans will start to heat up and you may notice some chaff (the outer layer of the bean) coming off.

  1. Listen for the first crack

After a few minutes, you’ll start to hear a popping sound coming from the roaster. This is known as the first crack and it signifies that the beans have reached the light roast level.

  1. Monitor the temperature

Keep an eye on the temperature of the roaster throughout the process. You can adjust the temperature if needed to achieve the desired roast level.

  1. Wait for the second crack

If you want a darker roast, wait for the second crack to start. This will happen a few minutes after the first crack and will sound more like a popcorn-popping sound.

  1. Stop the roasting process

Once you’ve achieved the desired roast level, turn off the roaster and remove the beans. It’s important to cool the beans down quickly to stop the roasting process, which can be done by pouring them into a colander and tossing them back and forth.

  1. Let the beans rest

After the beans are cooled down, let them rest for at least 24 hours before grinding and brewing. This allows the flavors to fully develop and ensures a better-tasting cup of coffee.

Overall, the air roasting process is a simple and effective way to roast your own coffee beans at home. With a little practice and experimentation, you can achieve your desired roast level and create a delicious and unique cup of coffee.

What’s The Difference Between Air Roasting and Drum Roasting?

When it comes to coffee roasting, there are two main methods used: air roasting and drum roasting. While both methods involve applying heat to coffee beans, the techniques used differ significantly. Here we’ll explore the differences between air roasting and drum roasting.

Fluidized Bed vs. Mechanical Arm

One of the primary differences between air roasting and drum roasting is the way the beans are agitated during the roasting process. In air roasting, the coffee beans are suspended in a fluidized bed of hot air, which agitates the beans and ensures even roasting. In contrast, drum roasting uses a mechanical arm to rotate the drum, causing the beans to tumble and roast as they come into contact with the hot drum walls.


The agitation method used in air roasting leads to a different taste profile than that produced by drum roasting. Air roasting tends to produce a cleaner, brighter taste, while drum roasting often results in a richer, more complex flavor. However, the taste also depends on other factors like the bean origin and roast level.


Another difference between the two methods is the way they handle the chaff, which is the thin skin that comes off the beans during roasting. In air roasting, the chaff is removed through a cyclone system, while in drum roasting, the chaff is removed by being blown out of the drum by a fan. This can lead to differences in the cleanliness of the roasting process.

Roasting Time

The final difference between the two methods is the roasting time. Because air roasting involves suspending the beans in hot air, the beans tend to roast more quickly and evenly than in drum roasting, which can take longer and result in less even roasting. However, some coffee roasters prefer the longer roasting time of drum roasting, as it can lead to a more complex flavor profile.

Overall, both air roasting and drum roasting have their advantages and disadvantages, and the choice between the two ultimately comes down to personal preference and the desired end result.

Is Air-Roasted Coffee Better?

Coffee is a beverage that people worldwide consume every day. It is essential to have good quality coffee that tastes great and is full of flavor. Air-roasted coffee is a popular method for making coffee that many people swear by. It has many benefits over traditional drum roasting methods. In this article, we will explore the question of whether air-roasted coffee is better and take a closer look at the benefits it offers.


One of the significant benefits of air-roasted coffee is its flavor. Air roasting allows for a more even roast of the coffee beans, resulting in a more consistent and flavorful cup of coffee. Additionally, the air-roasting process can also preserve the subtle notes and flavors of the coffee beans, which can be lost in drum roasting.

Roasting Time

Air roasting also has an advantage when it comes to roasting time. The process can be faster, resulting in a shorter roasting time compared to traditional drum roasting methods. The shorter roasting time can lead to a brighter and more acidic cup of coffee, making it an ideal option for those who prefer a lighter roast.


Another benefit of air roasting is that it produces less chaff, the dry skin on the coffee beans that separates during the roasting process. This means less cleanup and a cleaner coffee bean, which can result in a more consistent roast.

Overall, while traditional drum-roasting methods have their place in the coffee world, air-roasted coffee has several advantages. Its even roast, faster roasting time, and cleaner coffee beans make it an appealing option for coffee enthusiasts looking for a high-quality and flavorful cup of coffee.
