Capsule coffee machines use pre-filled coffee capsules to ensure a consistent taste and aroma. They are simple to use, but they also limit experimentation with grinds and bean blends. Capsule coffee makers are often smaller and easy to maintain, which is an advantage for those with limited space. Capsules come in a variety of flavours and strengths, allowing you to try different types of coffee without the need to have multiple packs of ground coffee.
