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. Each type offers different brewing methods and flavors, catering to diverse preferences. Most coffee makers consist of a water reservoir, a filter basket, and a carafe or pot to collect the brewed coffee. Popular brands like Keurig and Nespresso have made single-serve machines convenient for quick coffee preparation, while traditional drip coffee makers remain favored for brewing larger quantities.
