FrontStreet Coffee Shares Coffee Roasting
Coffee bean roasting refers to the process of heating raw beans to promote a series of physical and chemical reactions inside and outside the coffee beans. During roasting, the volume of coffee beans expands, becoming about one-third larger than raw beans.
Through the burning of fire during the roasting process, the aroma of coffee is released, bringing out the character of each bean—acidity, sweetness, and bitterness—in full expression. From bland raw beans to the mellow fragrance in the cup that leaves an endless aftertaste.
Roasting is the most important stop in the long journey of every coffee bean, where character is outlined and aroma is nurtured.
The roasting process is like popcorn, full of fragrance and pleasant popping sounds. From raw beans to light, medium, and dark roasts, moisture is released time and again, weight decreases, but volume slowly expands and swells. The color of the coffee beans deepens, aromatic oils gradually release, and the texture becomes crisp.
Raw beans contain large amounts of chlorogenic acid, which gradually disappears during the roasting process, releasing familiar and pleasant fruit acids—such as acetic acid, citric acid, and malic acid found in wine. Proper roasting can appropriately present these wonderful acids, while over-roasting will completely mask them.
