Ninja DualBrew vs DualBrew Pro – Which One Do You Buy

Dual (or two-way) coffee makers are popular pick for anyone who wants to enjoy their coffee in two ways: ground coffee or single-serve pods.

We’ve looked into dual coffee makers from many popular brands, most famously Hamilton Beach and Keurig. And now, Ninja as joined the party with their DualBrew coffee maker.

DualBrew vs. Hamilton Beach

The Hamilton Beach FlexBrew is one of the earliest two-way coffee makers available on the market. Here, I will be comparing the Hamilton Beach 49976 FlexBrew to the Ninja CFP201 DualBrew..

Auto Start for Carafe Brewing

To start, Hamilton Beach has two separate sides for each brewing method, the carafe brew and the single brew. Each side has its own separate water tank, too.

In fact, the 12-cup carafe brew side has a reservoir, but on the single-serve brew side, you’ll have to fill fresh water in the tank with the serving size you want to brew.

The single-serve side can use either K-Cup pods or ground coffee. The maximum serving size will depend on your method, it’s 12 oz for the K-Cups or 14 oz for the coffee ground.

Strength brew option allows you to make a bolder brew.

Digital clock allows you to set an auto start timer, but only for the carafe side.

Which Do You Pick?

Generally speaking, both the Hamilton Beach and Ninja DualBrew serve the same purpose. But there are a few things to consider:

  • If you care what your appliances look like, then first thing you’ll notice is how a lot modern looking the Ninja brewer looks. Since it uses one spout and reservoir for both brewing methods, it is slimmer in width and would look a lot nicer on a countertop.
  • While both machines have strength control, Ninja DualBrew has an ‘Over Ice’ option. This option takes into consideration the fact that you’re adding ice to your coffee that will melt and water it down. So while the coffee still brews hot, it will be bolder so it never tastes watery.
  • Budget-wise, there’s a huge price difference* between the two brands (*as of time of writing). If the Ninja DualBrew is within your budget, then you’ll love having a more modern machine with a sleek design and better functionality. But if all you really want is a good cup of coffee (and don’t care for the wider counter space you’ll need), the Hamilton Beach will be just fine of a choice.

Keurig’s K-Duo is another option for a two way coffee maker that offers a variety of brew sizes, including a full 12-cup carafe.

Like Ninja’s DualBrew, the K-Duo is available in two versions: K-Duo and K-Duo Plus. You can read about the two versions in a full post here.

Here’s a quick look at the features of the K-Duo:

Keurig K-Duo Coffee Maker, Single Serve and 12-Cup Carafe Drip Coffee Brewer, Compatible with K-Cup Pods and Ground Coffee, Black
  • What’s in the box: 12-cup glass carafe included with your brewer along with a heating plate to keep coffee hot.
  • Brew a cup and a carafe: Use both ground coffee and k-cup pods. Height with handle open-17.63 H inch. Height with drip cover open-18 H inch
  • Multiple brew sizes: Brew a 6, 8, 10, or 12-cup carafe and a 6, 8, 10, or 12 ounce cup.
  • Compatible with keurig gold tone mesh filter accessory: A reusable coffee filter you can use to brew your perfect carafe (sold separately).
  • Large 60 ounce water reservoir: The 60 ounce water reservoir is shared between the single serve and carafe brewing, saving you time and simplifying your morning routine. Removable reservoir makes refilling easy.

This model has a design that is similar to Hamilton Beach’s FlexBrew. It has two sides: the carafe brew side and the single-serve side.

On the full carafe side, you have the options to brew 6, 8, 10 or 12 cups of coffee. The included carafe is glass and a hot warming plate can keep it hot for several hours.

When brewing a K-Cup pod, you can brew serving sizes 6, 8, 10 and 12 oz. It is compatible with any type of K-Cup pod (branded, non-branded) as well as refillable cups, but if you choose to buy a 3rd party refillable pod, make sure it is compatible. Otherwise, you can opt for the official refillable pod from Keurig that is guaranteed to work with the machine.

Other options include: Pause and Pour – for pausing the brew cycle before it is fully complete. Strong Brew for a bolder coffee (works for the single-serve brew only). Programability and auto brew for the carafe side.

Reservoir size is 60 oz, shared between the single-serve and carafe side.

Features of the K-Duo Plus:

Sale
Keurig K-Duo Plus Coffee Maker, Single Serve and 12-Cup Carafe Drip Coffee Brewer, Compatible with K-Cup Pods and Ground Coffee, Black
  • What’s in the box: 12 cup thermal carafe and mesh reusable ground coffee filter included with your brewer
  • Brew a cup and a carafe: Use both ground coffee and k cup pods
  • Strong brew: Brew a stronger, more intense single cup and carafe
  • Multiple brew sizes: Brew a 6, 8, 10, or 12 cup carafe and a 6, 8, 10, or 12 ounce cup
  • Multi position 60 ounce; Water reservoir: Can be positioned to the right, left, or along the back of the brewer to optimize counter space

If you need a slimmer design, that is more in line to what the DualBrew by Ninja looks like, the K-Duo Plus is the model to consider.

The K-Duo Plus has a single spout design that can be used either for full carafe brewing or single cup brewing. It offers the same serve sizes as the K-Duo: 6, 8, 10 and 12 cups or 6, 8, 10 and 12 oz for single-serve brewing. It also has the same reservoir size, 60 oz, however, this time it is repositionable, it can sit behind or on the side of the machine, whichever suits your space best.

Another difference is the carafe, the K-Duo Plus has a thermal carafe. Therefore, it does not have a hot plate.

Everything else is similar to the K-Duo including: auto-start, programability, Pause and Pour and Strong Brew option.

Which Do You Pick

Although both Keurig K-Duo models and Ninja DualBrew offer the same functionality for the most part, The K-Duo Plus is the most comparable to the DualBrew due to its design.

When it comes to brewing styles and serving sizes, the DualBrew offers more variety. You’ll have the option of three or four brew styles (strength): Classic, Rich, Over Ice and Specialty (in the pro model only), this option is designed to replicate an espresso shot. The Pro version of the DualBrew also has a built-in milk frother – this, together with the Specialty option, allows you to make coffee drinks such as cappuccinos and lattes. None of Keurig’s K-Duo models has this option.

Personally, I am leaning towards the DualBrew by Ninja as a better option. It’s modern, offers more options and gives you a better user experience overall. However, there’s the subject of budget, too. There’s not a huge difference in price between the Ninja DualBrew and Keurig K-Duo Plus – you’ll have to check for yourself as prices change frequently.
