♡ Written by Humans for Humans

Typically Keurig manufactures only single-serve coffee makers, but the Duo series is an exception that can brew up to 12 cups Carafe of coffee simultaneously.

Duo Plus is essentially a 2-in-1 drip coffee maker that allows you to brew single-serve coffee with a K-cup pod or a full carafe of coffee with coffee grounds.

Keurig K Duo Plus review (A detailed Go Through)

1) Design and appearance of Keurig Duo Plus (5/5)

The Keurig Duo Plus has an attractive, sleek, and compact design with a matte black finish that fits seamlessly in your kitchen. It is more durable than any coffee maker that is made of plastic.

With the compact dimensions of 14.19 x 7.68 x 15.88 in. Keurig K-duo Plus is slimmer than Keurig K-duo or any Pot Coffee maker.

Overall, the design of this coffee maker is quite stylish and way more compact than other 12-cup carafe drip coffee makers.

2) Performance of Keurig K Duo Plus (5/5)

I would like to give a 5-star rating to this model for its performance. This multi-functional coffee maker can brew a single-serve cup in 6, 8, 10, or 12 oz cup sizes or 6, 8, 10, or 12 cups of coffee in carafe mode.

The heat up time of machine is pretty fast, it takes only 40-50 seconds to get ready to brew.

Single Serve mode:

Once preheated, the brewer can whip up a single cup of coffee in just a minute. Simply insert a K-cup pod, choose your desired cup size, and press the brew button. In under a minute, you’ll be enjoying a steaming hot cup of coffee.

The machine is compatible with all the branded and 3rd party k cups or you can also use reusable K cups.

It can easily accommodate travel mugs up to 8 inches after removing the drip tray and 7.25 inches without removing the drip tray.

Carafe Mode:

The carafe efficiently brews 6 cups in 5-7 minutes and a 12-cup carafe in just 9-10 minutes, an exceptional brewing speed that outpaces any other drip coffee maker I’ve come across.

A handy brew-pause function is integrated into the Carafe mode. To grab a quick cup while the machine is brewing, simply lift the carafe and pour your coffee. The machine will automatically halt brewing for 20 seconds before continuing.

For a truly smooth and sediment-free cup of coffee, I strongly advise using disposable paper filters instead of the built-in mesh filter.

I have tested the temperature of brew both in the Carafe and single-serve modes multiple times and it typically falls in the range of 172 to 177 degrees. And that is quite impressive.

3) Taste and the quality of coffee drink (4/5)

In terms of taste, there is no significant difference between the Keurig K-duo Plus and other Keurig coffee machines. (Which is quite decent but obviously not the best!)

This Keurig model steps up its coffee game with the strong brew option. This feature extends the brewing time, leading to a more comprehensive extraction of flavors from the coffee grounds, resulting in a richer, more intense cup of coffee.

Regarding the taste of the drink, this machine lacks two very important features usually found in Keurig machines in this price range: a 4oz serving size option and an over-iced setting. You will probably not like this machine if you enjoy iced coffee or small espresso-style shots of coffee for preparing Latte and Cappuccino.

Overall, I am quite satisfied with the temperature and taste of the drink this machine prepares.

4) Ease of use (5/5)

The Keurig Duo Plus is an extremely user-friendly machine, seamlessly integrating intuitive controls and a clear display screen. It allows users to effortlessly access all functions and prepare their desired coffee beverages with ease.

Keurig Duo Plus has a simple power button to turn the machine Off or On. When you turn on the machine carafe and pod button starts blinking. Once you choose one option the 6, 8, 10, and 12 size button starts blinking.

Just add the coffee pod or coffee grounds, select the size, and hit the large K button as simple as it is.

The auto button and the time buttons on the left, provides you with the ability to program the machine to brew a fresh pot of coffee at your desired time.

I’m impressed by the simplicity of this machine’s interface. Even with its dual brewing capabilities for single servings and carafes, it remains remarkably user-friendly.

5) Ease of cleaning (3/5)

The Keurig Duo Plus’s components, including the filter basket, gold-tone mesh filter, carafe, and carafe lid, are readily detachable, allowing for easy cleaning. Note that these parts require manual cleaning, as they are not dishwasher-safe.

The machine’s exterior features a polished, shiny finish and can be readily cleaned with a damp cloth.

The drip tray and water reservoir are also conveniently removable for effortless cleaning.

6) Water Reservoir of Keurig Duo Plus (5/5)

The best thing about this coffee maker is the convenient design of the water reservoir.

The water reservoir is completely made of see-through plastic and it has marks on it for 12, 10, 8, and 6 cups of coffee.

You can easily adjust the position of the water reservoir either on the back or left and right-hand side of the brewer depending on the available space.

Additionally, it has a convenient handle that makes it easy to attach and detach from the brewer, as well as easy to clean.

The water reservoir of Keurig Duo Plus can accommodate tall handle water filter to eliminate impurities from water.

It is undeniably the convenient design of the water reservoir of Keurig Duo Plus that earns it its unique selling point.

7) Other Features

Thermal Carafe

Unlike Keurig Duo with a glass carafe and heating plate, Duo Plus has 12-cup stainless steel insulated thermal Carafe. A thermal Carafe is better in my opinion as it is long-lasting and can keep coffee hot for 2 hours without the need for a heating plate.

Auto shutoff feature

Keurig Duo Plus has an auto shut-off feature that automatically shutt off the machine after 10 minutes of inactivity.

8) Price (3/5)

While the price tag of around $200 may initially seem high for this coffee machine, its exceptional quality and range of features make it a worthwhile investment.

Features like the auto brew setting, the adjustable water reservoir, the pause and pour settings, and the versatile one-cup and multi-cup serving options justify its higher cost. And obviously Keurig has a brand value too!

9) Customer Reviews (4.5/5)

No matter what the features or specifications of a coffee maker the real worth is always determined by the users. And it seems that the users are quite satisfied with this machine.

On Amazon, it has around 25k reviews with an average rating of 4.5 out of 5. Almost 80% of the users are completely satisfied with this machine. This is a very good number though.

On the negative side, some users are not happy with the carafe and brew pause function of this machine. They have complaints about leakages and the poor design of the carafe.

Overall, customers are mostly satisfied with the functioning and the taste of Keurig Duo Plus

You Are Limited In Space: With the dimensions of 14.19 x 7.68 x 15.88 in. Keurig k-duo plus is slimmer than many carafe coffeemakers. Also, the multi-position design of the water reservoir makes the design ideal for smaller places.

You are Tight On Budget: Although this machine has many unique features but it isn’t cheap at all. Look for other options if you are tight on budget you can easily get a coffee maker with similar functionalities for under 150 dollars. As we all know Keurig charges for its brand name also.

Espresso-styled coffee: There is no option to brew a 4oz cup of espresso-styled coffee in this machine. This small shot of coffee is very useful in preparing strong Latte and Cappuccinos. All high-end Keurig machines usually have this feature. I wonder why they haven’t included it.
