The K-Duo coffee maker has a 72 oz. single water reservoir that is shared between single serve and carafe brewing, which means fewer water refills to save you time. The included 12-cup glass carafe and heating plate are perfect for keeping your coffee hot, and the added convenience of the Pause & Pour feature makes serving a snap! No need to wait for the entire carafe to brew - the Keurig K-Duo coffee maker can be paused mid-brew for 20 seconds, so you can pour fresh, hot coffee right away. Or set your preferred brew time up to 24 hours in advance and enjoy a freshly brewed carafe right when you want it with Programmable Carafe Auto Brew.
