The only type of coffee that is compatible with a Keurig B40 Elite coffee brewer is the coffee that is pre-packaged inside Keurig's patented K-Cups. The machine can be used to brew any type of coffee or tea served in a K-Cup in two distinct brew size options.
The Keurig B40 Elite coffee brewer is also designed to show if the machine needs descaling and automatically shuts itself off after two hours. Prior to use, the machine requires four minutes to ready itself and requires 1500 watts of power. The Keurig B40 also includes a drip tray and a 48-ounce water container that can be removed.
