Single-serve coffee makers are compact machines designed to brew one cup of coffee at a time. They use pre-packaged coffee pods or capsules, which contain ground coffee, making the brewing process quick and convenient. Users simply insert a pod, add water, and press a button to enjoy a fresh cup of coffee in minutes. These machines are popular for their ease of use and minimal cleanup. Many models offer various brew sizes and flavors, catering to different preferences. Brands like Keurig and Nespresso are well-known for their single-serve coffee makers, providing a wide range of options for coffee lovers.
