A coffee maker is a kitchen appliance designed to brew coffee by heating water and passing it through ground coffee. There are various types of coffee makers, including drip coffee makers, single-serve machines, and espresso machines. Most models have a water reservoir, a filter basket, and a carafe to collect the brewed coffee. Using a coffee maker is generally straightforward. Users fill the reservoir with water, add ground coffee to the filter, and start the brewing process. The machine heats the water, which then extracts flavors from the coffee grounds, resulting in a fresh cup of coffee ready to enjoy.
