Coffee roasting is a genuine form of art. Green coffee beans do not have that typical ‘coffee’ flavor. The specific flavor is obtained through coffee roasting. Although the green coffee bean, prior of roasting, includes caffeine, protein and complex acids, but it has a taste that has nothing to do with the coffee we are accustomed to.

The Art and Science of Coffee Roasting

Coffee roasting is a fascinating blend of art and science that transforms green coffee beans into the aromatic,The Art and Science of Coffee Roasting Articles flavorful beverage we all love. While green coffee beans contain caffeine, proteins, and complex acids, they lack the familiar coffee taste. This transformation occurs through the intricate process of roasting, which converts the beans' carbohydrates and fats into aromatic oils, releasing carbon dioxide and moisture, and decomposing acids to create that remarkable coffee flavor.

The Chemistry Behind Coffee Roasting

During roasting, the heat initiates a series of chemical reactions. The Maillard reaction, for instance, occurs between amino acids and reducing sugars, leading to the development of complex flavors and aromas. Additionally, caramelization of sugars contributes to the sweetness and color of the roasted beans. These reactions are crucial in defining the final taste profile of the coffee.
