Keurig brewers' supporting product is called K-cups; which are small plastic cups, lined with filters, and contain coffee grounds. A seal is then placed on the cup. Keurig also offers reusable K-Cups. A handle is located on the top front side of the machine, once you lift the handle, the K-Cup is placed in the designated position. When you close the brewer, you cut a hole in the K-Cup. The hot water is then heated and pushed through the k-cup into the cup located underneath the machine. Keurig has a wide range of brewing systems, from single-cup brews to brewers with reservoirs to hold more water. They also offer a Keurig espresso specializing in steamed milk. Keurig's suggested retail price ranges from $90 to $200 USD. As of September 2014, the company has sold over 45 million brewers worldwide. These brewing systems offer a quick way to brew a fresh cup of coffee every time. (Keurig Green Mountain,
