The majority of us mere mortals depend on coffee to get through the day. But convenience and quality can be hard to find.

If you’re over long lines at the cafe or you’re disappointed by the stale coffee pot in the employee lounge, it’s time for an upgrade- a Keurig upgrade.

Our Keurig K-Supreme Plus review takes an in-depth look at a model designed to brew bold coffee without sacrificing convenience. Let’s dive in!

Keurig K Supreme Plus Design Overview

Keurig is the brand that introduced the pod concept to the coffee market in the 1990s and never looked back. The result was revolutionary, bringing convenient single-serve coffee to hustling individuals everywhere.

There are several Keurig models, each one utilizing the same brew process with a variety of features. Instead of grinding, measuring, and pulling your coffee grounds, K-Cups take care of it for you.

Simply place a K-Cup in the Keurig machine, hit the Brew button, and you’re off to the races.

In today’s review, we set our sights on the Keurig K Supreme Plus. This sleek, stainless steel beauty is an upgrade from the K Supreme Keurig, with a similar build but more variety and durability.

We’ll discuss the difference between Keurig K Supreme and K Supreme Plus in more detail later. But for this article, the main focus will be on the Keurig Supreme Plus.

To start, the coffee maker’s dimensions are compact at 13.3” L x 8.3” W x 12.2” H. It weighs a featherlight 7.7 pounds, making it an ideal choice for homes and apartments with limited counter space.

This Keurig model only brews coffee, tea, and cocoa, but its highlight feature is the MultiStream technology that greatly improves the quality of the brew.

The K-Supreme Plus is incredibly easy to use, with Keurig K Supreme reviews mentioning how quietly it operates. You get plenty of options for customizing your drinks, and you can even save your preferences for later.

Without a doubt, this may be one of our favorite Keurig models, where simplicity meets dang good coffee with one push of the Brew button. Best of all, the price is below $200, which means if you’re a casual coffee drinker on the go, you may love what the K Cup Supreme has to offer.

As mentioned above, the Keurig K Supreme Plus is a solid upgrade of the Keurig K-Supreme, and it’s only slightly more expensive.

The Keurig team gave it quite a makeover, and while the build looks the same and both models utilize the game-changing MultiStream tech, some comfort features make the Plus a better deal, in our opinion.

The most notable difference between the two is that the new Keurig K Supreme Plus is made with stainless steel parts, which is more durable than the plastic design of the original K Supreme coffee maker.

Besides a shiny silver exterior, the Plus also has a robust water tank that holds 78-oz of water while its predecessor holds a smaller66-oz tank.

One thoughtful feature that the original has and the Plus doesn’t is a dual-position water tank. You can attach it either on the side or the back of the machine to make the most of your counter space.

Still, you get a lot of other extras that the original just can’t compare with, such as five brew sizes, the ability to save your coffee preferences, and three temperature controls. The original K-Supreme does not have this kind of variety.

So which one is better? Honestly, we are 100% for the Keurig K Cup Supreme Plus. Stainless steel looks more refined compared to plastic, and it lasts longer, too.

You get more coffee customization to brew your way and a bigger water tank for less time wasted with refills.

But mainly we were ecstatic about the price. The Keurig coffee maker Supreme Plus doesn’t break the bank. For just a bit more money, you get better quality and more variety.

K Supreme Plus Keurig Features

Pod coffee is often looked down upon by coffee snobs. In the coffee world, grinding your own fresh coffee beans and pulling a perfect espresso shot is an art form.

Relying on a plastic capsule of preground coffee? Don’t expect the same flavor experience.

But Keurig aims to improve the pod experience with the Supreme Plus. While it’s still not at the same level as semiautomatic or superautomatic, it gives casual drinkers a decent cup of coffee with very little effort.

Water Reservoir

Removable water tank and coffee pod of the Keurig Supreme Plus

The Plus’s 78 oz removable water tank is larger than most reservoirs you’ll see on the single-serve market, brewing nine drinks per tank. This is important because it means fewer refills and more convenience.

Besides the size of the tank, check for a filtration system, as it plays a pivotal role in the longevity and overall taste of your coffee.

Allow us to explain.

Hard water from your kitchen tap is filled with minerals that build up inside your coffee machine. Over time, these mineral deposits can clog parts and cause damages that shorten your coffee maker’s lifespan.

A water filter can help, and thankfully, the Keurig K-Supreme Plus does have space in the reservoir to install one.

A filter purifies the water, which reduces the need to descale often. Filtered water also enhances the flavors and aromas of your coffee.

Of course, it’s recommended to go with a Keurig K Supreme Plus water filter, but know that this is a separate purchase.

If you don’t want to buy more Keurig K Supreme Plus accessories, you can opt for distilled water or use filtered water from another source.

Because of the tank size, we recommend this model for large households with multiple coffee drinkers and for office settings since you won’t have to refill as often.

Brewing Capabilities

The highlight of the K Supreme Plus coffee maker is the implementation of MultiStream Technology.

It works by shooting multiple streams of water through the K-Cup to fully saturate the grounds for a thorough extraction of flavors and aromas. This improves the profile of the coffee, allowing the drinker to enjoy a full-bodied sensory experience.

You won’t find this technology in other single-serve models that use only one stream of water for coffee extraction.

And Keurig K Supreme reviews say that MultiStream does make a notable difference. This changes the single-serve game, as one of the drawbacks of pods is the lack of control over the flavor and strength.

Not only does the coffee taste divine, but you also get a playground of preferences to customize, which is rare with single-serve coffee makers.

It brews hot drinks but can also be dispensed over ice to make iced coffee and tea. You can adjust the coffee strength and temperature choosing from three levels for each setting.

The Plus can brew five different amounts of coffee for 6oz, 8oz, 10oz, and 12oz in a single go. It’s even compatible with 7” tall travel mugs.

One fun feature is that you can save three user profiles. So if you love a particular recipe you brewed up, just save it.

Next time you make coffee, you won’t have to go through the motions selecting the preferences- it’s all set for your brewing pleasure.

Heat-up time is lightning quick, and the Plus can do back-to-back brewing without warm-up between sessions. In two minutes or less, you’re in coffee nirvana.

There’s only one drawback we could find with the brewing, and that’s the K-Cup variety. It only takes K-Cups and not K-Carafe® pods, K-Mug® pods, Vue® pods, or Rivo® pods.

It’s not a serious dealbreaker by any means, especially since there are hundreds of K-Cup varieties to choose from.

You also purchase the My K-Cup® Universal Reusable Coffee Filter separately and use your coffee grounds instead of pods.

Even though it costs more, we do think it’s worth it because fresh ground coffee offers the best flavor profile, and it reduces single-use plastic waste.

Keurig Supreme Plus Coffee Maker Setup & Operation

Setting up Keurig K Supreme Plus is a breeze, with a small button panel that is user-friendly. You don’t have to deal with a bunch of levers and knobs, and there’s no strategy to unlock the secrets of the professional barista.

Instead, you just place a pod in the holder and push the brew button. Voila!

When you first purchase the Keurig K Supreme Plus stainless steel, there is an initial brew cleansing procedure to follow before you start juggling K-Cups.

We’ve outlined the steps below to give you an idea.

1. Pick a Home for Your New Keurig Machine

Find a flat, dry countertop to house your Keurig Supreme single-serve, and plug it into a power source. Place a large mug on the drip tray.

2. Prep the Water Tank

Remove the water tank from the left side of the machine and rinse it out under the faucet. Once clean, fill it with fresh filtered water to the MAX line. Snap the tank back into place on the machine.

3. Initiate the Cleansing Brew

Lift and lower the pod holder, then lock it into place (note that you do not place a K-Cup into the holder for this cycle). When the holder is locked, the 5 cup size lights will blink. Choose the 8-oz button, then hit BREW.

The machine will thoroughly flush the entire system. Once the mug is filled with hot water, dump it out. You are now ready to add a pod to the holder and brew coffee following the same steps.

Keurig K Supreme Coffee Maker Cleaning Process

Regular maintenance is a critical part of owning a coffee maker. The more you maintain your machine, the longer it will last.

Some coffee makers are more hands-off than others when it comes to cleaning, but unfortunately, that’s not the deal with the Plus.

The exterior must be wiped down with a damp cloth every other use. Never immerse the brew system in the water!

The drip tray can hold up to 8oz of liquid before dumping. Make sure to rinse it out whenever you dump the liquid.

And don’t forget to remove the water tank and rinse it out with soap and water now and then– you don’t want bacteria to make it their new home.

How often you undertake these tasks depends on how often you brew coffee, but note that these are the basic maintenance tasks.

You’ll also need to disassemble the brew system and wash each part by hand. This includes the following:

  • K-Cup pod holder
  • Funnel
  • Exit needle
  • Entrance needles

The K Supreme Plus C Keurig manual gives step-by-step instructions on how to disassemble, clean, and reassemble each of these parts.

We were disappointed that you can’t wash them in the dishwasher, as some Keurig models do have this capability. This just makes the cleaning process painstaking.

After each use, you can run the brew cleansing cycle, which is easy to do and will ensure any loose coffee grounds are washed away.

But your maintenance adventures are far from over.

You also need to be on top of descaling to remove mineral build-up. That’s why a Keurig K Supreme Plus water filter comes in handy to cut down on descaling. At least, the machine will alert you that it’s time to descale after every 250 brews.

If you love single-serve coffee makers but wish the drink quality wasn’t so drab, then the Keurig Supreme K Cup Plus might just be the dream machine for you.

Keurig implemented its innovative MultiStream Technology to improve extraction, shooting multiple streams of water into the pod instead of a single stream. This allows for a rich flavor experience that is rare to find with single-serve machines.

You also get a satisfactory array of customization features, including three coffee strengths. This is an often missed detail with single-serve coffee makers.

You can only brew coffee, tea, and cocoa, but do note that you have the option to make hot or iced drinks, which is something you don’t even see on many superautomatic coffee machines.

And finally, you can’t beat the price. You get to enjoy a great-tasting cup of coffee in under two minutes without dishing out thousands on a large, heavy machine.

We recommend the K Supreme Single-Serve Plus for…

  • Small to large households with multiple coffee drinkers
  • Small to medium office settings
  • Casual coffee drinkers who don’t care about specialty milk drinks
  • Busy individuals who need to brew coffee fast when they’re on the go

Each one is a single-serve model that falls within the same price range as the K-Supreme Plus.

For a slightly lower price, the Keurig K Elite gives users a similar feature set to the Supreme Plus, including five brew sizes, a strong brew option, and a 75-oz water tank. It’s fast, too, and can brew a cup of coffee in under a minute.

Keurig K-Supreme Plus Review Conclusion

The new Keurig K Supreme Plus is a straightforward single-serve coffee maker that bolsters the coffee pod experience with a more full-bodied coffee. Long gone are the days where you have to just accept one coffee strength. The MultiStream extraction and three coffee levels let you brew your way.
