Smoky
Smoky is an aroma reminiscent of burnt food or charred wood, commonly found in dark-roasted coffee and often regarded as a desirable characteristic in cupping.
The smoky note develops when coffee beans are roasted at high temperatures, generating compounds such as guaiacol and 4-methylguaiacol. However, if the roasting process is not well-controlled, the smoky aroma can become overpowering, diminishing the overall flavor quality.
Perception of smoky flavors varies depending on individual preference – some appreciate its bold intensity, while others consider it a sign of over-roasting.
