Roasting on the Valenta
Air Roasted vs. Gas Roasted Coffee: Does It Really Taste Different?
If you've ever shopped for specialty coffee, you've probably seen the terms air roasted and drum roasted. But what do they actually mean, and more importantly, can you taste the difference?
The short answer is: yes, but maybe not in the way you think.
At Longshot Coffee Roasters, we roast every batch on a Coffee Crafters Valenta 15, an air roaster designed to produce clean, consistent, and flavorful coffee. Here's why we chose it and what it means for the coffee in your cup.
What Is Gas (Drum) Roasting?
Traditional coffee roasting uses a rotating metal drum that's heated by gas burners. As the drum heats up, coffee beans tumble inside while receiving heat from both the hot metal surface (conduction) and the surrounding hot air (convection).
This method has been around for generations and is used by many of the world's best coffee roasters.
When done well, drum roasting produces incredible coffee. Like any roasting method, the final flavor depends far more on the skill of the roaster than the machine itself.
What Is Air Roasting?
Air roasting uses a stream of hot air to suspend and roast the coffee beans rather than relying on a hot metal drum.
Because the beans are surrounded by moving hot air, they're heated more evenly and don't spend time resting against extremely hot metal surfaces.
The result is a roasting process that's highly responsive, incredibly consistent, and easy to fine-tune throughout the roast.
How Does It Affect Flavor?
One of the biggest reasons we chose air roasting is the cup quality.
Many coffee drinkers describe air-roasted coffee as:
Cleaner and brighter
More transparent, allowing the bean's natural characteristics to shine
Better at highlighting delicate fruit, floral, and citrus notes
Less likely to develop smoky or overly roasted flavors
Because the beans are heated more evenly, it's often easier to preserve the unique flavors that make each coffee special.
If you're drinking a washed Ethiopian coffee with notes of blueberry and jasmine, you want those flavors to stand out, not get buried under heavy roast character.
That's exactly what air roasting helps us achieve.
What About Smoke?
During roasting, coffee naturally releases smoke and tiny pieces of chaff (the papery skin surrounding the bean).
On some traditional drum roasters, if smoke isn't managed well, it can recirculate around the beans and contribute additional smoky flavors.
The Coffee Crafters Valenta 15 continuously moves air through the roasting chamber while separating chaff from the beans. This helps create a cleaner roasting environment and allows the coffee's natural flavors to remain front and center.
Consistency Matters
One of the biggest advantages of modern air roasting is repeatability.
Our Coffee Crafters Valenta 15 gives us precise control over airflow, temperature, and roast development, allowing us to roast each coffee consistently from batch to batch.
That means when you fall in love with one of our coffees, you can expect it to taste the way you remember the next time you brew it.
Consistency isn't flashy, but it's one of the most important ingredients in great coffee.
Is Air Roasting Better?
Not necessarily.
A skilled roaster with a traditional gas drum roaster can produce exceptional coffee. Likewise, an air roaster in inexperienced hands won't magically make great coffee.
The roasting method is simply one tool.
What matters most is:
Starting with high-quality green coffee.
Understanding how each origin behaves during roasting.
Carefully developing each roast to highlight the coffee's best qualities.
Maintaining consistency from batch to batch.
We believe air roasting gives us an advantage in achieving those goals, but it's our roasting philosophy - not just our equipment - that ultimately makes the difference.
Why We Chose the Coffee Crafters Valenta 15
When we were deciding how to roast our coffee, we wanted equipment that reflected our philosophy.
The Coffee Crafters Valenta 15 allows us to roast in small, carefully monitored batches while emphasizing clarity, sweetness, and balance.
Our goal isn't to roast coffee that tastes like the roasting process.
Our goal is to roast coffee that tastes like where it came from.
Every coffee has a story: from the farm and the variety to the processing method and the people who grew it. We want those flavors to make it all the way into your cup.
That's why we air roast every bag we sell.
Taste the Difference
The best way to understand air roasting isn't by reading about it—it's by tasting it.
Whether you're brewing a bright single origin or one of our signature blends, we hope you'll notice the clean finish, balanced sweetness, and flavors that make each coffee unique.
Because great coffee shouldn't taste like smoke.
It should taste like coffee.
