Decoding Roast Levels: What Happens during the Roasting Process?

During the roasting process, coffee beans undergo various chemical reactions. Initially, the beans lose moisture and undergo a series of physical changes.

As the temperature rises, the beans undergo Maillard reactions, leading to the development of flavor compounds.

In the later stages, the beans begin to crack, and the degree of cracking determines the roast level.

Here’s a breakdown of what happens during the roasting process:

  • Moisture loss: Beans lose moisture, becoming lighter and more brittle.
  • Physical changes: Beans expand in size and change color, transitioning from green to yellow and then to various shades of brown.
  • Development of flavor compounds: As the temperature rises, Maillard reactions occur, resulting in the formation of flavor compounds that contribute to the taste of coffee.
  • Bean cracking: Beans undergo two distinct cracks during the roasting process. The first crack indicates a light to medium roast, while the second crack signifies a darker roast.

Understanding the roasting process provides insights into the transformation coffee beans undergo.

The interplay between time, temperature, and chemical reactions determines the roast level and the resulting flavor characteristics.

Factors Influencing Roast Levels

Several factors influence the roast level of coffee.

The duration of roasting, the temperature applied, and the desired outcome all play a role.

Additionally, different coffee varieties and origins may respond differently to the roasting process.
