What is fluid bed roasting and why we use it.

Fluid Bed Roasting

Have you had coffee leave you with a sour stomach and an unpleasant, jittery feeling throughout your body? Or one that tastes burnt and bitter? We usually attribute these characteristics to a particular style of coffee roast or brand of coffee. Maybe it’s neither. In many cases, it’s the roasting equipment causing the undesirable flavors. You might stumble onto this realization by having a cup of extraordinary coffee, as we did, ask what made it so, and discover – Air Roasted Coffee!

With Air Roasted Coffee you taste the coffee, not the roaster. It’s the air that roasts the coffee not the surface of the roaster. So the coffee has an intensely aromatic and very clean taste, minus the acids and bitter tars that are produced by conventional roasters. This roasting method was championed by Michael Sivetz, Chemical Engineer, and Coffee Industry Consultant. He wrote the first scientific treatise on coffee, Coffee Technology. Disappointed with the state of roasting manufacturing, he developed and manufactured the first practical commercial air roaster: the Fluid-Bed Roaster.

Most drum roasters today introduce hot air into their roast chamber, then the beans tumble and touch the hot surfaces to roast, like clothing in a clothes dryer. The Fluid-Bed system levitates the beans on a fluidized bed of hot air, keeping the beans moving and not scorching on hot surfaces (as shown in the pic above). The sole use of hot air greatly increases the rate of heat transference to the beans, creating a cleaner, more aromatic roast free of bitter tasting tars. 

This is why we prefer air roasting over the traditional drum method. You'll experience a more savory, palatable, and full-flavored boldness without any of the harsh bitterness or acidic tastes. Additionally, one other major benefit of fluid bed roasting is the mere fact that it makes black coffee more enjoyable. Those who enjoy a dairy and sugar-free cup will have a much better and enjoyable experience with air roasted coffee due to a smoother and less bitter taste.  

Our company does our best to satisfy your tastes and lifestyle in regards to coffee. We think of everyone from the specialty coffee-type, as well as the black coffee drinker. That's why we've chosen air roasting because it is truly the best method for not only roasting our coffee but for satisfying everyone's needs based on taste. We encourage you to try some of ours and provide us with any valuable feedback about tasting notes, roast, smell, and anything else you can think of. We're always down to talk about coffee and your experiences!
