The coffee roasting process is essential to transform raw beans into aromatic and flavorful products ready for consumption. Without roasting, coffee beans would not develop the complex flavor profiles that coffee lovers cherish.

What Is the Coffee Roasting Process?
The coffee roasting process involves heating raw coffee beans to specific temperatures to develop unique flavors and aromas. During roasting, the beans undergo critical chemical and physical changes that define their sensory characteristics.
At Lucky Hills, for example, roasting is done in small batches and on demand, a method that allows for meticulous control over each stage of the process. This careful roasting is crucial for highlighting the integrity of the unique flavors, ensuring exceptional freshness and quality in every delivery. This way, the coffee reaches consumers with its flavors and aromas preserved, offering a precise, refined, and authentic sensory experience.
What Are the Stages of the Coffee Roasting Process?
The coffee roasting process consists of several stages, each critical for developing the final flavor and aroma of the beans:
-
Selecting Coffee Beans
The coffee roasting process begins with the selection of high-quality raw coffee beans, as the origin, variety, and processing method of the beans significantly influence the final flavor profile.

Preheating the Roaster
Before starting the roast, the roaster must be preheated to a specific temperature to ensure the beans receive uniform heat from the beginning. This preheating is essential for an even roast and to avoid flavor imbalances.
-
Initial Drying Phase
In the initial drying phase, the moisture in the coffee beans is eliminated. This phase typically lasts 4 to 8 minutes, during which the beans change from green to yellow. Drying is crucial to prepare the beans for the chemical reactions that occur in subsequent stages.
-
First Crack
When the beans reach a certain temperature, depending on the roaster’s methods, the first crack occurs—an audible pop that indicates the start of internal transformations in the beans. This stage is vital for flavor development, as it marks the point where the beans begin to expand and release internal gases.
-
Development Phase
After the first crack, the beans enter the development phase, where temperature and time are carefully controlled to achieve the desired flavor profile. In this phase, the acidity, sweetness, and bitterness of the beans are balanced. The development time can vary, directly influencing the sensory characteristics of the final coffee.
-
Second Crack (Optional)
For darker roasts, a second crack may occur at a higher temperature. This stage adds deeper flavors and reduces the beans’ original flavor notes. Roasts that go through the second crack tend to have a more robust and full-bodied flavor profile.
-
Cooling
Once the desired roast level is achieved, the beans need to be cooled rapidly to stop the roasting process and prevent over-roasting. Cooling can be done using air or water methods, and the ideal process should be quick to preserve the flavors and aromas developed during roasting.
-
Degassing and Resting
Roasted beans release carbon dioxide in a process known as degassing, which can last from a few hours to several days. During this time, the flavors of the beans stabilize, resulting in a more balanced and pleasant coffee.
It’s worth mentioning that this is the commonly used coffee roasting process. However, other methods, such as wood-fired roasting, infrared roasting, and hot air roasting, impact the final result and provide different flavor profiles.
Types of Coffee Roasts: Light, Medium, and Dark
Coffee roasting can be classified into three main types, depending on the roast level:
-
Light Roast
Light roast preserves most of the original flavors of the coffee beans, resulting in coffee with high acidity, light body, and fruity or floral notes. It’s ideal for those who enjoy a brighter and more acidic flavor profile.
-
Medium Roast
Medium roast provides a balance between acidity and body. The beans have a medium-brown color, and the flavor profile is sweeter and more balanced, with notes of caramel and nuts. It’s a popular choice for its harmonious flavor.
-
Dark Roast
Dark roast results in beans with a dark brown, almost black color. This type of roast reduces acidity and increases bitterness, offering coffee with a robust body and notes of dark chocolate or toasted flavors. It’s preferred by those who enjoy a stronger and more intense flavor.
As mentioned, the coffee roasting process is crucial for maximizing the potential of the beans. Every stage, from bean selection to cooling, is essential for defining the final quality of the coffee, highlighting the beans’ unique characteristics and reflecting their origin and processing methods.
