Robusta Roasting Profiles, often overshadowed by its Arabica counterpart, holds a unique charm for those seeking a bolder, more intense coffee experience. While inherently stronger and less acidic, unlocking its full potential lies in understanding its distinct roasting profile. This guide delves into the intricacies of robusta roasting, empowering you to craft a cup that resonates with your taste buds.

Pay attention to the first crack: This marks the point of rapid moisture loss and the beginning of flavor development.
Monitor color changes: Observe the beans closely for even color development and avoid scorching.
Cool the beans quickly: After roasting, rapidly cool the beans to prevent over-roasting and trap volatile flavors.
Rest the beans: Allow roasted beans to rest for at least 24 hours before brewing for optimal flavor extraction.
