The designers behind the popular Keurig K-Supreme line of coffeemakers have added a new and technologically advanced option to join the Keurig K-Supreme and the Keurig K-Supreme Plus. 

Released in July 2021, the Keurig K-Supreme Plus SMART brings your morning cup of coffee to the cloud with the ability to connect to both wifi and your phone. It builds on the excellent technology that allowed the previous models to make such great coffee by adding state-of-the-art features that increase convenience and ease of use. 

In this review of the Keurig K-Supreme Plus SMART, we’ll cover everything you need to know about this brand new smart coffee maker and compare them to the older models in the K-Supreme line.

When it comes to k-cup pod coffee, no one knows the technology or the market better than Keurig. After all, they are the company that first popularized the now-ubiquitous method of coffee brewing. If you love the convenience of K-cups, you can’t go wrong with a machine from Keurig. If you are a fan of K-Cup coffee, also check our Top 9 Keurig coffee machines review.

The Design and Build 

From an appearance standpoint, the K-Supreme has a sleek and modern design that will likely complement the other appliances in your kitchen. The simple black design draws your eye and the stainless steel metal wrap makes it more elegant.

The transparent plastic removable water reservoir sits on the side of the machine, keeping it mostly out of sight but also easy to remove for cleaning and to refill with water. You can tell at a glance whether or not you have enough water to make your morning cup of coffee. However, you can’t change the position of the water tank like the plus version.

Like most Keurigs, it comes with a removable drip tray so you can fit travel mugs in.

The LED control panel is located at the top of the brew chamber, allowing you easy access to all the control — we’ll get into the variety in a second. 

The K-Supreme Plus SMART feels very solid and well built with an exterior of black stainless steel and hard plastic. You won’t have to worry about chipping or breaking any crucial parts.

How Smart Is It?

This is a fair question, given the name of the product we’re looking at. This section will examine the wifi connectivity and other technological features that come in the K-Supreme Plus Smart. 

Brew ID 

In terms of pure coffee brewing, the Keriug Brew ID features give you unparalleled control over your cup of coffee. The innovative system changes factors like water temperature and brews to provide you with a cup of coffee that suits your unique tastes. 

When you put a pod into your Keurig K-Supreme Plus Smart brewer, it will recognize the type of coffee you’re trying to brew by reading the label. This means that your machine won’t, for example, brew a pod that contains medium roast coffee in the same way that it will brew a dark roast. Coffee experts have figured out the ideal brew conditions for different coffees, and this smart machine can make it happen automatically. 

The BrewID technology works just as well for brands of coffee that aren’t directly produced by Keurig, giving you access to a world of different blends and tastes while still taking advantage of the automatic adjustment of brew settings. 

Smart In-App Control 

The addition of a smartphone app is the most notable feature that sets the K-Supreme smart brewer apart from other models in the K-Supreme line. It brings the convenience of smartphone connectivity to a fundamental appliance in most people’s homes—the humble coffee maker—and proves what a difference it makes. 

Aside from the basic act of loading the pod into the machine, just about everything you need to do to get your K-Supreme Plus Smart to start brewing coffee can be made on your smartphone. 

Here are some other great features that let you enjoy good coffee with ease.

Schedule Your Brew

The most obvious use for the smartphone app is on those sleepy mornings when you don’t want to get out of bed without a hot cup of coffee that’s already done. You can stop dragging yourself out of bed only to face the agonizing wait for your coffee to finish brewing. Instead, you can turn on the coffee machine without getting out of bed and wait for the notification that tells you your cup of coffee is ready. 

Customize And Store Your Brew Settings

You can also explore all the customization options and establish presets for your favorite combinations on your phone. You can adjust the strength, temperature, and cup size you want (with 4 oz, 6 oz., 8 oz., 10 oz, and 12 oz. options). 

Once found your sweet spot, you can save the settings as your favorite. It’s great to be able to choose whether you want a big, strong cup of coffee in the morning or a small, light one from the comfort of your bed or your patio, respectively.

Voice-Controlled Brew (Support Alexa & Google Home)

The number of other systems that your coffee maker can connect to is simply astounding. For instance, if you have an Alexa or Google Home system in your house, you can turn on the coffee machine using voice commands!

Smart Auto-Delivery

Lastly, another great feature is the auto-delivery system that tracks how many pods you’ve used and automatically orders your coffee pods of choice from the internet. That’s one item on your to-do list taken care of.  

There are still more features packed into the smartphone app. Based on the history of the beverages you’ve brewed, as well as your brew settings, the Keurig app recommends blends that you haven’t tried yet. By keeping track of what you like to drink, the app’s recommendations for new drinks are uncannily good.

How Is the Coffee Quality? 

This model of the K-Supreme comes with the same innovative brewing technology that the K-Supreme Brewer and K-Supreme Plus Brewer introduced. 

In a nutshell, the exceptionally high brew quality of the K-Supreme line of coffeemakers comes from the unique Multistream technology in the machine, which injects five streams of water into your pod during the brewing process. 

What does that mean? 

Well, the idea behind using multiple sprouts revolves around how evenly a machine can saturate the coffee grounds in a pod. Imagine you had a machine that injected water into your pod through only one hole. The coffee surrounding that injection site will have released all of its flavor (and more), while the water will barely have touched coffee at the edges of the pod. 

Since the K-Supreme line uses five different streams of water evenly spaced around the pod, you can be sure you’ll get the full flavor out of it. 

Ease of Use 

With all the convenient features packed into the K-Supreme Plus Smart coffee maker, it’s no surprise that the machine is a breeze to operate once you’ve put them all together and everything is connected. 

The privilege of turning on your coffee maker from bed can’t be understated—at least until you’ve had a night out and it comes in handy the following day. Although many other coffee makers come equipped with a timer, allowing you to set a specific brew time, you’ll only find cold coffee in your cup if you oversleep. 

Especially if you get used to controlling your smart appliances at home with Alexa or Google Assistant, ‘Alexa, brew me coffee’ will become the first thing you say when you wake up.

Value For Money 

When it comes to evaluating the K-Supreme Plus Smart in terms of the value of the money you spend, there are two different comparisons you need to make. Firstly, you need to compare the Plus Smart to other machines in the K-Supreme product line. Secondly, there also has to be a comparison of the K-Supreme Plus Smart to machines from different brands with similar technological connectivity levels. 

Comparing the price point of the K-Supreme Plus Smart to other Keurig machines is pretty straightforward: the machine that comes with wifi connectivity and a smartphone app is more expensive. But, it’s not much more costly. 

It’s a little bit of a bigger job to compare the smart version of Keurig’s coffee makers to the smart coffee makers that other brands offer. Based on extensive market research, we can tell you that the K-Supreme Plus Smart isn’t very much more expensive than any other coffee maker with similar capacities. In fact, it’s often cheaper. 

With that in mind, the comparison is between the quality of the coffee that the competing machines can offer. And, as we’ve gone over, if you’re a fan of K-cups, the company that invented them isn’t a bad bet.

K-Supreme Vs. K-Supreme Plus Vs. K-Supreme Plus Smart

When you’re trying to decide between the three different K-Supreme models, you need to consider the differences between the three machines. If all you want is a very basic coffee maker, the K-Supreme model is a great option. But, if you want some more features, you need to consider the K-Supreme Plus and the K-Supreme Plus Smart. 

On each point, the vital question to ask yourself is whether the extra feature you get from a more expensive and advanced machine is worth it. For instance, if you really love iced coffee, all three models will work for you because they all have this setting. But, if you value setting up presets for your brew preferences, controlling the brew strength or temperature, you’ll have to go with the K-Supreme Plus or the K-Supreme Plus Smart. 

Once you get to the level of deciding between the two more advanced models in the K-Supreme line, you need to answer whether the extra convenience of having a smartphone-connected coffee machine justifies the additional cost relative to other Keurig coffee machines. 

Finally, Who Would Love the K-Supreme Plus Smart?

It’s pretty clear that the K-Supreme Plus Smart is for consumers who are serious about using tech to make their lives easier. It’s not your grandmother’s coffee maker. 

Getting the more advanced machine is a no-brainer if you already have the technological infrastructure (and the know-how) to take advantage of the K-Supreme Plus Smart capabilities.

For just one example, it also takes a lot of weight off to know that you’ll constantly have coffee due to the auto-delivery system with which the Keurig K-Supreme Plus Smart comes. There’s little more annoying than waking up to find that there’s no coffee in the cupboard—this isn’t ever going to happen again if you go for the SMART version of Keurig’s K-Supreme line. 

This is the sort of convenience you’re paying for when you get an internet-enabled coffee machine. 

Frequently Asked Questions

Can I Use a Reusable K-Cup with the K-Supreme Coffee Maker?

Yes, you can use a reusable K-Cup with a K-Supreme Coffee maker if you want to use your own freshly ground coffee in your machine. Just make sure you buy a reusable K-Cup with five holes on the top. Otherwise, it won’t be compatible with the Multistream technology.

How To Descale Descale Keurig K-Supreme Coffee Maker

Descaling any of the K-Supreme coffee makers is a straightforward process. All you have to do is fill the right amount of descaling solution and water to the water tank, use the built-in descale mode, and wait, discarding the liquid afterward.
