The Keurig K-Cup is a coffee brew system in which enough coffee grounds for a single cup of coffee are separately packaged, allowing for Keurig owners to make one cup of coffee at a time. Keurig manufactures many different brewing systems with differing levels of complexity; there are brewers that are connected to the building water pipes and there are standalone brewers that require manual loading of water. The B60 is one such brewer.
