What is dark roast coffee, and how is it different from lighter roasts?
Dark roast coffee is a type of coffee that has been roasted for a longer period than lighter roasts, resulting in a richer, bolder flavor and a darker color. The roasting process involves heating the coffee beans to high temperatures, which causes the beans to expand in size and change color. Dark roast coffee is typically roasted to an internal temperature of around 460°F (238°C), whereas lighter roasts are roasted to around 400°F (204°C). This longer roasting time gives dark roast coffee its distinctive flavor and aroma.
The longer roasting time also affects the chemical composition of the coffee beans. Dark roast coffee has a higher concentration of certain compounds, such as melanoidins, which are formed during the Maillard reaction – a chemical reaction between amino acids and reducing sugars that occurs when the beans are heated. These compounds contribute to the rich, bold flavor and dark color of dark roast coffee.
