Coffee capsules are small, pre-packaged containers filled with ground coffee, designed for use in specific coffee machines. They offer a convenient way to brew a single cup of coffee without the need for measuring or grinding beans. Each capsule is sealed to preserve freshness and flavor, making it easy to enjoy a consistent cup of coffee. These capsules come in various flavors and strengths, catering to different taste preferences. Popular brands, such as Nespresso and Keurig, have developed their own systems, ensuring compatibility with their machines. This innovation has made coffee brewing quicker and more accessible for many coffee lovers.
