Roasting coffee is an art form, and like all art, it comes with its set of challenges. Whether you're a seasoned roaster or just starting out, it's important to know how to troubleshoot common roasting mistakes.

Over-roasted Beans
One of the most common mishaps is over-roasting. This results in a burnt taste, with overly dark beans losing their origin flavors.
Fix: Reduce the roast time or lower the temperature, particularly during the final stages. Monitoring your beans closely prevents them from surpassing the ideal roast level.
Recommended Coffee:
-
French Roast – Dark Roast, Full-Bodied, Smoky Overtones & Bittersweet Depth
Perfectly crafted for those who enjoy a robust flavor profile, without crossing the line into bitterness.
Under-roasted Beans
When beans are under-roasted, they retain a grassy taste and can lack complexity.
Fix: Extend the roast duration or slightly increase the initial temperature to ensure full development.

Uneven Roasting
