Understanding Roast Stages

First Crack

First crack is a critical point during the roasting process where the beans undergo an audible crack or pop. It marks the beginning of the coffee’s development and indicates that the sugars and other compounds within the beans are caramelizing. This stage is associated with lighter roast profiles and brings out bright and acidic flavors.

During first crack, the internal temperature of the beans rapidly increases, and they begin to expand and release residual moisture. The cracks themselves can be indicative of the roast level, with a longer and louder first crack associated with darker roasts.

Development Time Ratio (DTR)

The Development Time Ratio (DTR) is a metric used to analyze the proportion of time after first crack to the total roast time. It gives roasters insights into how long the beans have been in the development phase relative to the overall roast duration.

DTR is often used as a tool to evaluate the balance between acidity, sweetness, and body in a coffee. A higher DTR tends to result in a sweeter and fuller-bodied cup, while a shorter DTR may produce brighter, more acidic flavors.

Roast Levels

Roast levels refer to the degree to which the beans have undergone the roasting process. They are typically categorized into light, medium, and dark roasts, with each level offering distinct flavor profiles and characteristics.

Light roasts preserve the unique qualities of the beans, highlighting their acidity and floral or fruity notes. Medium roasts strike a balance between the bean’s natural flavors and the caramelization brought on by longer roasting times, offering a more well-rounded and balanced cup. Dark roasts are characterized by bold, rich flavors and often have a smoky or chocolatey undertone due to prolonged roasting.

Understanding roast levels is essential in creating roast profiles that cater to different preferences and tastes.
