When the Keurig 2.0 range of brewers first launched, customers didn’t like the pod-scanning system. It locked in owners to Keurig K-pods only. And they could no longer use unlicensed K-cups.

After a struggle with the backlash, Keurig decided to scrap the entire product line.

But in an effort to offer a dual-use coffee maker that could brew both a full carafe or single cups, it launched the Keurig K-Duo.

However, if you have special requirements or expectations, then maybe you should check out other alternatives which may be a better fit.

2. Are there any other alternatives to the Keurig K-Duo model?

Minor variations in features and functionality of the Keurig K-Duo coffee maker are seen in the similar K-Duo Plus and K-Duo Essentials models.

  • K-Duo Essentials costs a little less, but is missing the 6 oz brew size, and brew strength adjustment.

If the K-Duo is priced out of your budget, then a simpler but more affordable model like the Keurig K-Mini or Keurig K-Express are excellent alternatives.

On the other hand, for a more versatile and feature-rich coffee making experience, the more impressive Keurig K-Cafe or Keurig K155 Office Pro models might be worth considering.

Keurig K-Duo Coffee Maker Review - Design

The machine looks elegant and appealing.

It matches almost any interior decor. And even though it is bigger than most Keurig models, is not really very bulky.

With a sleek black and silver color tone, it will fit right into any modern kitchen.

A Keurig K-Duo is conveniently designed with an adjustable water reservoir that’s shared by both single-serve and carafe parts.

This offers the choice of

  • placing it behind or
  • on either side of the coffee machine.

The reservoir is removable, making it easy to refill after use.

Ease of Use

Ease of use remains the stronghold of any Keurig coffee maker. And the Keurig K-Duo model is no exception to the rule. Operating this coffee machine is intuitive and easy.

All you have to do is

  • fill the water reservoir
  • add coffee grounds or K-pods to the filter basket
  • place a carafe on the drip tray
  • power on the machine and select ‘Carafe’
  • pick your brew size (6 to 12 cups)

Then just sit back for a couple of minutes while your delicious cuppa brews!

An Auto-Brew function takes away even this minimum effort. All you have to do is pick that mode – and everything is done for you.

You can simply choose the auto-brew option, and have the K-Duo decide everything for you.

Or for customization, there are some buttons to adjust aspects like coffee strength and brew size.

All buttons are clearly labelled with descriptive pictures, which makes it easy for even beginners to use the machine.

A reusable mesh filter makes it convenient to brew delicious coffee with either K-cup pods or fresh coffee grounds. It also reduces the hassle and expense of replacing a filter each time.

Keurig K-Duo Review


Most Keurig K-Duo coffee maker reviews agree that the quality of coffee is very good.

With great variability possible, you can enjoy regular coffee or a choice of specialty drinks like chai latte, cappuccino, hot cocoa or green tea.


Keurig K-Duo coffee maker review : Performance


The hot plate keeps your brew warm for upto 5 hours in the carafe.

One drawback a coffee purist might point to is a lack of customization.

While you can adjust coffee strength with the ‘Strong Brew‘ feature, there are no settings to alter water temperature, or a milk frother for creamy drinks.

Brew Size

For single-serve brewing, you can choose from between 6, 8, 10 or 12 oz cups.

For carafe brewing, you have a choice of 6 to 12 cups.

The Keurig K-Duo is compatible with large 7″ travel mugs.

Special Features

A programmable Auto-Brew feature enables you to pre-set the Keurig K-Duo coffee maker to brew a carafe of coffee any time upto 24 hours in advance.

Pause and Pour is another interesting feature that makes it convenient for anyone to interrupt a brewing cycle to pour themselves a cup of hot, fresh coffee. There’s no need to wait until the entire batch is brewed.

Auto Shut-Off

The K-Duo saves energy by automatically turning the machine off 5 minutes after brewing the last single cup.

While brewing in carafe mode, the hot plate will run for 2 hours – after which the coffee maker will turn off automatically.

Cleaning & Maintenance

Keurig K Duo review - Cleaning

The K-Duo coffee machine needs regular maintenance and cleaning.

  • After each use, the carafe, filter basket and mesh filter must be washed clean using soapy water. No part is dishwasher safe.
  • Wiping the exterior with a damp cloth helps remove grime and dust from the surface.
  • Once in 3 months, the manufacturer recommends descaling. This helps remove calcium and other deposits in the interior.
  • Instructions are available on the Keurig website.

It is simple, involving a brew run using vinegar or a descaling solution, and then a couple of clear water runs to wash it out.

The needle also must be declogged often, to ensure good coffee quality.

Keurig K-Duo Review

Price and Affordability

The Keurig K-Duo is not a cheap coffee maker. It’s also not a terribly costly premium coffee machine.

Given the performance standards, aesthetic design, programmability and extra features, this is a fairly priced coffee maker.

If you like the option of having both drip coffee and single serve coffee, the K-Duo is a better option – than getting 2 different coffee makers!

While other less expensive options no doubt exist, there are few that offer dual-brew capability at lesser cost.

And this Keurig coffee machine offers excellent quality for its price, making it great value for money.

1 Year Warranty

There’s a manufacturer’s warranty of 1 year against defects and flaws. It further safeguards your investment into this popular coffee maker.

Make sure to register your Keurig coffee maker online after you purchase it, in order to avail of this warranty.
