About

Dark roasts proceed well into second crack, reaching 230-240°C. The bean surface is visibly oily and dark brown to nearly black. Most origin-specific flavor compounds have been transformed by pyrolysis into roast-derived compounds — carbon, quinic acid, and Maillard melanoidins. Dark roasting requires its own expertise: achieving boldness without acrid bitterness demands precise airflow management and rapid cooling. While often dismissed by specialty purists, skilled dark roasting produces genuinely enjoyable bold coffee for consumers who prefer smoky intensity over fruity brightness.
