1. Brews A Cup and A Carafe

As the name suggests, Keurig K Duo Coffee Machine is a duo coffee maker. It provides two brewing options- you can either make a single cup of coffee or you can brew coffee for your whole family using the carafe. A carafe is a container that has the capacity to store 12 cups of coffee. There are 3 various cup options- 8, 10 and 12 oz- for you to choose from.

2. Works With Pods And Ground Coffee

This is one of the features which has made the Keurig K- Duo Coffee Maker loved in the world of coffee lovers. It allows you to brew coffee using k-cup pods and ground coffee. Both ground coffee and k-cup pods lovers can use this machine to make their preferred coffee. It is recommended that you brew a single cup using a k-cup pod. While, if you are using the carafe, use ground coffee.

3. Huge Water Reservoir

Since the machine provides two various brewing options, it is assumed that it has two separate tanks. However, it is not true. The Keurig K- Duo Coffee Maker has a single water reservoir which can store 60 oz of water. This tank is divided between the two brewers. Its single huge reservoir has various benefits-it saves time and energy as there is only 1 reservoir to refill and the water is also provided for a longer time.

4. Pause And Pour Feature

This smart feature sets this model apart from the rest. The Keurig K- Duo Coffee Maker has a smart feature which allows you to pause brewing and pour a cup of coffee. This makes your morning faster as you do not have to wait for it to be done with the heating process. Unlike the rest of the models, the Duo Coffee Maker lets you choose your preferred cup even after you power on the machine.


1. Glass Carafe

Users have to be extremely careful with the carafe as it is made up of glass and has higher chances of breakage. The glass does not retain heat too well so there are chances that you may get scalded as well. It is recommended that you have a warming plate. If this drawback bothers you then you may want to think again before buying this machine. There are other options available as well.

2. Plastic Build

The plastic build does not go well aesthetically with the plastic housing. The k-cup pod door also looks easily breakable. These k-cup pods can only be used if you are making coffee for a single cup. Those who wish to use the carafe are only limited to using ground coffee. This is one of the major drawbacks which can cause harm if consumers are not careful. It can get messy too.
