☕ What Happens When Coffee Is Roasted?

Before coffee becomes the aromatic beverage we know and love, it goes through one of the most important stages in its journey: roasting. 🔥

Green coffee beans have very little aroma and a mild, grassy flavor. It is only through roasting that coffee begins to develop the rich flavors and fragrances found in every cup.

As the beans are exposed to heat, they gradually change color from green to yellow, then light brown, and eventually darker shades of brown depending on the roast level. 🌿➡️🟤

One of the key processes that occurs during roasting is known as the Maillard Reaction. This natural chemical reaction happens when amino acids and sugars interact under heat.

The Maillard Reaction is responsible for creating hundreds of aromatic compounds that contribute to coffee's complex flavors, including notes of chocolate, caramel, nuts, and toasted bread. ☕🍫

As roasting continues, the beans expand, release moisture, and develop their unique characteristics. The roasting profile ultimately influences acidity, sweetness, body, and aroma.

Roasting is both a science and an art. A carefully roasted coffee can highlight the unique qualities developed during cultivation and processing.

From a green bean to a fragrant cup, roasting is where coffee truly begins to reveal its character. 🌿☕
