Nespresso aims to provide the best coffee quality that they can in a convenient format. The capsules ensure that the perfect amount of coffee is brewed every time, minimizing waste and maximizing flavor. Unfortunately, that usually means that the capsules are more expensive than the bulk ground coffee you may be used to. The flavor, consistency, and convenience make them well worth the investment for those Nespresso lovers out there, but it is up to you to decide how worthwhile the investment is to you.
