Eco-Friendly Roasting
Discover the PhDifference in our roasting process. Using innovative, eco-friendly fluid bed roasting, we deliver consistency, enhanced flavors, and reduced carbon footprint - all in a single roasting cycle.
Eco-Friendly Innovation: The Power of Fluid Bed Roasting
At PhDuo Roastery, we’re proud to roast on the Artisan XL and Artisan 3-e from Coffee Crafters. These powerhouse roasters combine efficiency, consistency, and quality—perfect for both small experimental batches and full-scale production. Together, they allow us to roast anywhere from a half-pound to over 6 pounds at a time, achieving production rates that easily exceed 25 lbs per hour while maintaining our signature precision and roast control.
The Artisan XL and 3-e are energy-efficient, fluid-bed marvels that ensure a clean, even roast while consuming as little as 0.4 kWh per pound of electricity. Using clean hot-air roasting technology, they bring out the best in every bean—delivering a smoother, brighter cup while keeping our footprint small.
Fluid-bed roasters like these revolutionize coffee roasting by suspending beans in a cushion of hot air, creating uniform heat transfer and reducing roast times. This method minimizes the formation of unwanted bitter compounds and accentuates the natural sweetness and complexity of our ethically sourced coffees.
Both roasters feature smart heat recirculation systems, reusing energy from the roasting process to preheat incoming air and cut CO₂ emissions by up to 25%. This makes our operation not only more efficient but also among the most sustainable in the industry.
Finally, air roasting removes chaff during the roast, preventing smoky aftertastes and preserving the pure flavor of the coffee. Though relatively new in the commercial space, air roasting has earned a reputation for producing exceptionally clean, vibrant cups.
At PhDuo Roastery, we blend innovation and tradition—pairing state-of-the-art air-roasting technology with time-honored craftsmanship to deliver a cup that’s as conscientious as it is delicious.
From Root to Roast: Our Commitment to Sustainable, Fair Trade Coffee
At PhDuo Roastery, we believe that a great cup of coffee starts with its roots. That's why we import our beans directly from small farms in developing regions worldwide, where coffee cultivation not only contributes to local economies but also carries deep cultural significance. We have committed ourselves to sourcing only fair trade beans - an affirmation of our support for just compensation and improved living conditions for these dedicated farmers. Every purchase of our coffee supports a chain of fairness and sustainability, reaching back to these vibrant communities around the world.
Sustainability is more than a buzzword to us; it's an ethos that we strive to reflect in every aspect of our operations. Importing coffee from small farms, as opposed to large plantations, allows us to ensure traceability and promote farming practices that are gentle to the environment. It is in these small-scale operations where coffee growing works in harmony with the ecosystem, nurturing biodiversity and preserving vital habitats. By sourcing our beans in this way, we contribute to a greener future for coffee, and in turn, for our planet.
Finally, the respect and care that we bring to our roasting process are second to none. Utilizing eco-friendly fluid bed roasting technology, we ensure that each batch is treated with meticulous precision, yielding a more consistent, superior quality roast. This method not only improves the taste but significantly reduces our carbon footprint, making our roastery one of the most sustainable choices for coffee enthusiasts. Every bean we roast carries a unique story from its place of origin, and we aim to honor that journey, delivering its distinctive character and flavors from our roastery to your cup. At PhDuo Roastery, we brew more than just coffee - we brew 'Coffea Vitae', the Coffee of Life.
