Testing Fluid-Bed Roasting with Atok, Benguet Single Origin
Filipino Coffee Manufacturing Inc. (FCMI) operates as the research and development arm of Teofilo Coffee Company.
While Teofilo Coffee Company focuses on café experience, community, and service, FCMI works behind the scenes—prototyping, testing, and validating coffee products before they ever reach a menu, wholesale partner, or retail shelf.
This separation allows us to move with intention.
Teofilo serves the cup.
FCMI builds the foundation behind it.
Why Atok, Benguet Single Origin?
For this round of testing, we used Atok, Benguet single-origin coffee—a high-altitude Arabica known for its density, structure, and naturally bright acidity.
Atok Benguet is not forgiving.
It exposes underdevelopment, uneven heat application, and rushed roasting decisions quickly.
That makes it ideal for R&D.
If fluid-bed roasting can truly influence perceived acidity without flattening flavor, Atok Benguet will show it.
Why We Chose Practical, Accessible Tools
All tools used in this testing process are accessible to most cafés and small roasteries. That choice was intentional.
While we have access to high-end testing equipment, early-stage R&D doesn’t require expensive lab setups. Using practical tools allows us to:
- Run more iterations
- Stay grounded in real café conditions
- Avoid unnecessary spending early in the process
- Reserve advanced testing for final validation when needed
Good data doesn’t need to be expensive.
It needs to be repeatable, understood, and applied correctly.
Our Testing Setup
Measurement
- DiFluid TDS tester for extraction and solubility evaluation
Brewing Methods
- Cold brew
- AeroPress
- Fetco batch brewer
Roasting Platform
- Artisan Xe fluid-bed roaster, used as our primary R&D and prototyping system
This setup reflects how coffee is actually brewed and served in cafés, which makes the results more meaningful and transferable.
Why We Ran This Test
One of the most common claims around fluid-bed roasting is that it can reduce perceived acidity by applying heat more evenly and developing coffee internally rather than aggressively on the surface.
Instead of assuming that claim was true—or dismissing it—we tested it.
Using the same Atok Benguet coffee, we roasted multiple profiles at different end temperatures and development percentages. Each version was evaluated across:
- Hot brew
- Espresso
- Cold brew
No forced conclusions.
No chasing a narrative.
Just roasting, brewing, measuring, tasting, and comparing.
An Open Lens Leads to Better Coffee
We weren’t trying to erase acidity.
We weren’t trying to prove fluid-bed roasting “better.”
We were observing how:
- Bean structure changes with roast temperature
- Solubility behaves across brew methods
- Acidity presents when development is controlled rather than rushed
That openness is the advantage of having FCMI as a true R&D arm. We get to test freely, stay disciplined, and let the coffee show us what’s happening—without pressure to force an outcome.
And honestly, that’s what makes the work enjoyable.
How This Feeds Back Into Teofilo Coffee Company
Everything learned at FCMI directly informs what Teofilo Coffee Company serves.
This process helps us:
- Design espresso that extracts cleanly without bite
- Build cold brew that’s smooth without being flat
- Improve consistency in batch brewing
- Respect the natural character of Atok Benguet while making it more approachable
By starting with practical tools and scaling testing only when needed, we develop coffees that perform in real cafés—not just controlled environments.
Closing
FCMI exists so we can ask honest questions—and let the coffee answer honestly.
We test because we’re curious.
We measure because we care.
We don’t force outcomes, and we don’t rush conclusions.
That balance between discipline and discovery is what allows Teofilo Coffee Company to serve coffee with confidence—and consistency.
This is Filipino coffee, developed with purpose.
