What is coffee roasting?

Coffee enthusiasts often find themselves captivated by the magic of coffee roasting, a process that transforms ordinary green coffee seeds into flavorful beans that are brewed into great cups of coffee. You might have even asked what is coffee roasting or how coffee roasting works. At Tapestry Coffee, we embrace this transformation with enthusiasm, working with exceptional green coffee to create a diverse and delightful range of roasts.

Understanding Coffee Roasting

Definition and Importance:

Coffee roasting involves the application of various types of heat to induce chemical and physical changes in green coffee. It's a seemingly simple process, but in practice, it requires precision and expertise. The careful application of heat not only caramelizes sugars and browns the coffee but also triggers a cascade of other changes, resulting in a product that is both familiar and pleasantly surprising.

The Three Types of Heat Transfer in Roasting

Understanding the three fundamental types of heat transfer—conduction, convection, and radiance—is crucial in coffee roasting. At Tapestry Coffee, we leverage all three methods, employing Mill City roasters that emphasize conduction and convection.

The Art of Roasting: Tapestry's Formula

Our approach to roasting follows a simple formula: great green coffee plus the right amount of heat and time equals superbly roasted coffee. This is why we put so much time and focus into our coffee sourcing efforts. We truly work to source the best green coffee possible to make sure we end up with a great end product. Roasting styles vary, impacting flavor through factors like roast intensity, duration, and temperature.

Explaining The Steps of Coffee Roasting

1. Initial Drop of Green Coffee into the Drum: The journey of coffee roasting begins with the ceremonious drop of green coffee beans into the roasting drum. This marks the inception of a meticulous process that will unfold the distinct characteristics hidden within each bean.

2. The Turnaround: As the beans commence their dance within the roasting drum, the turnaround is a critical juncture. It signifies the point where the beans start absorbing heat, undergoing the initial transformation from green to the warm tones of yellow.

3. Green to Yellow: The transition from green to yellow is a visually arresting phase in coffee roasting. The beans undergo a significant color change, indicating the activation of chemical reactions within. It's a delicate dance of flavors taking shape.

4. First Crack: The first crack is a defining moment in the roasting process. Audible and exhilarating, it signals the beans' internal structure breaking down. At this point, the sugars caramelize, and the coffee enters a realm of complexity, offering a spectrum of flavors.

5. Drop to the Cooling Tray: As the desired roast level is achieved, the beans make their final descent into the cooling tray. This rapid cooling halts the roasting process, locking in the intricate flavors developed during the journey.
