Importance of Coffee Roasting

Coffee roasting is like unlocking the flavor vault of coffee beans. The duration and temperature of roasting impact their taste, aroma, and even texture. Additionally, roasting influences the caffeine content, acidity, and body of the coffee, resulting in a diverse array of brews to suit every palate.

How To Roast

01

Dehydration

Removing moisture helps prevent the beans from steaming or popping during roasting, ensuring even heat distribution and promoting consistent roasting.

Maillard Reaction

This reaction produces a wide range of flavor compounds, including those that contribute to the characteristic roasted, caramelized, and nutty flavors of coffee.

03

Endothermic Aggregation

The endothermic phase allows the beans to absorb heat and undergo chemical changes that contribute to the development of acidity, sweetness, and other desirable flavor characteristics.

Caramelization Reaction

During this phase, the beans undergo further caramelization and flavor development. Controlling the duration of this phase is crucial for achieving the desired balance between acidity, sweetness, and bitterness in the roasted coffee.
