How does roast degree influence the taste of coffee?

• A. It has no effect on extraction quality
• B. Lighter roasts are traditionally preferred in Southern Italy
• C. Darker roasts are often less acidic than lighter roasts
• D. Roast levels are essential for optimal extraction

Answer: (D)

Roast degree significantly influences the taste of coffee by affecting the chemical composition of the beans, which in turn impacts extraction during brewing. Different roast levels alter the balance of flavors, acidity, and body in coffee. For instance, lighter roasts tend to retain more of the original flavors of the coffee beans, highlighting their acidity and nuances from the origin, while darker roasts become more developed in flavor through the Maillard reaction and caramelization of sugars. This development often results in a reduced perception of acidity and the emergence of smoky, bitter, or chocolatey notes in darker roasts. Understanding the roast profile is crucial for baristas and coffee enthusiasts, as it guides them in selecting the appropriate brewing method and parameters to enhance flavor extraction. Achieving optimal extraction is essential to bringing out the best characteristics of the coffee, which is why roast levels play a pivotal role in this process.
