Keurig K-Duo Single Serve and Carafe Coffee Maker
A space saving pod and carafe combo held back by a drippy carafe and cool brewing.
The short version
- Households that mix single cup and full pot coffee drinkers
- Small kitchens that only have room for one coffee maker
- Anyone who wants a pot ready on a timer in the morning
- You care most about coffee flavor and want a brewer that reaches full brewing temperature
- You want a thermal carafe instead of a heating plate
- You only ever make pod coffee
What owners like
- One machine covers both pod cups and full pots, which saves counter space
- Large shared reservoir means refilling only every few days for light use
- Simple button layout that reviewers could set up without the manual
- Quick from start to finished cup and easy to clean
Common complaints
- Glass carafe tends to drip or leak when pouring
- List price feels high for a fairly basic feature set
- Brews cooler than the range coffee experts recommend, which can mean weaker flavor
- K-Cup holder takes a firm push to close, and some hear a squeak while heating

What it does
A Keurig brewer that makes single cups from K-Cup pods on one side and a 12 cup glass carafe of ground coffee on the other, sharing one water tank.
- Programmable auto brew for the carafe, with a digital clock
- Strong brew setting for a bolder cup
- Pause and pour lets you take a cup from the carafe mid brew
- Heating plate keeps the carafe warm for about two hours, then shuts off
- Carafe side takes ground coffee in a basket filter, paper or reusable mesh
- Height adjustable drip tray on the single serve side
A practical pick for a household where one person wants a quick pod cup and another wants a pot of drip coffee, without two machines on the counter. The trade-offs are a glass carafe that reviewers found drips when pouring, a brew temperature measured below the usual ideal range, and a list price that two reviews called high for the features, so it makes most sense on sale.
