As a coffee roaster, we understand the importance of a clean, pure taste in every cup. That's why we use the hot air roasting method, which results in coffee with less acidity and bitterness than traditional drum roasting.

The secret lies in how we manage the chaf, or outer husk of the bean. With traditional drum roasting, there is no way to remove the chaf from the drum, leading to undesired flavors in the brewed cup, especially in darker roasts. But with our hot air roasting process, a continuous flow of hot air blows through the beans and removes the chaf as it breaks away from the beans. This eliminates the risk of unwanted off-flavors and results in a clean, pure taste that you'll love.


Unlike traditional gas and drum roasting methods, which rely on heat transfer through the metal surface of the drum and result in uneven roasts and flavors, our hot air roasting process guarantees an even roast every time. Our beans levitate and rotate through a bed of continuous hot air, ensuring consistent temperature and even heat distribution on all sides for a perfectly roasted and flavorful cup of coffee.

We roast our beans "to temperature," which means we stop the roasting process at a predetermined time and temperature for a perfectly roasted bean every time. This method allows for more precision, enabling us to duplicate batches and produce the same color, flavor profile, and aroma that our coffee drinkers have come to love.

Experience the difference that precision and consistency make in your cup of coffee with our hot air roasted coffee. Whether you prefer a light, medium, or dark roast, our hot air roasting process guarantees a consistently delicious and satisfying cup of coffee every time.
