A cup of coffee is a popular beverage made by brewing ground coffee beans with hot water. The process extracts flavors and caffeine, resulting in a rich, aromatic drink. Coffee can be served in various styles, including black, with milk, or sweetened, and is enjoyed worldwide. Coffee is often consumed in the morning to help wake up and increase alertness due to its caffeine content. It can be prepared using different methods, such as a French press, espresso machine, or drip coffee maker. Many people also enjoy coffee socially, often meeting friends at a café.
