Nespresso is a brand of espresso machine that uses pre-filled aluminum ground coffee capsules as well as the name of the capsules themselves. It was the first single cup machine available and has always focused on espresso rather than regular coffee. The name is a combination of Nestle (the manufacturer) and espresso. There are a few companies that make Nespresso machines, including Breville and DeLonghi, both of which show up in our list.
