Coffee preparation involves several key steps to transform raw coffee beans into a delicious beverage. First, the beans are roasted to develop their flavor, with different roast levels affecting the taste. Once roasted, the beans are ground to a specific coarseness depending on the brewing method, such as French press, espresso, or drip coffee. Next, hot water is used to extract flavors from the ground coffee. The brewing time and temperature are crucial, as they influence the final taste. After brewing, the coffee can be served black or with additions like milk, sugar, or flavored syrups, depending on personal preference.
