Capsule coffee refers to a method of brewing coffee using pre-packaged capsules or pods. These capsules contain ground coffee sealed in a protective casing, ensuring freshness and convenience. Users simply insert a capsule into a compatible machine, which punctures the capsule and brews coffee by forcing hot water through it. This process allows for a quick and consistent cup of coffee with minimal cleanup. The popularity of capsule coffee has grown due to its ease of use and variety of flavors. Major brands like Nespresso and Keurig offer a wide range of coffee options, catering to different tastes and preferences. This brewing method appeals to busy individuals seeking a fast and hassle-free coffee experience.
