Keurig® K-Supreme Single Serve K-Cup Pod Coffee Maker, MultiStream Technology, Gray

As we mentioned above, the Keurig K-Supreme is more a recent addition to the Keurig family of coffee makers. It brings new and improved features to the world of coffee brewing, including multistream technology that produces a bolder cup and it has an adjustable water tank. We’d recommend the Keurig K-Supreme for anyone who wants the ease of a Keurig with physical flexibility that allows it to fit in anywhere.

The Keurig K-Classic’s name is very fitting, as it is the quintessential Keurig. Indicator lights on the top make it easy to use and its generously sized water tank will allow you to brew multiple cups in a row before needing to add more water. Get this one if you want an affordable Keurig that’s great for beginners.


Color Options

Whether you’re putting your Keurig in your home office or your kitchen, you might be interested in having a model that matches with your décor. Either the Keurig K-Classic or the K-Supreme is available in two different colors.

Frankly, this won’t have an impact on your daily coffee brewing. However, it does give you a little more flexibility as far as aesthetics go.


It’s easy to forget to shut off your appliances when you’re in a rush or you’re tired. The K-Supreme and the K-Classic are both coffee makers you won’t need to be worried about if you accidentally leave them on.

If they’re on for a certain amount of time without anyone brewing coffee, they will automatically turn themselves off. The benefit of this feature is threefold: it reduces energy consumption, prevents them from generating a higher utility bill, and protects them from the harm of running for long periods of time if you forget to power them off.

Removable Drip Tray

Both these Keurigs have removable drip trays. They’re situated right beneath the dispenser so that they can stop any coffee drips from making a mess on your counter.

Wondering why you’d want to remove them? It’s simple: removing the drip trays allows you to empty and clean them somewhere more convenient. Furthermore, you can make extra room beneath the dispenser by removing them, which allows you to brew into larger cups.

Indicator Lights

Do you hate having to play the guessing game when it comes to troubleshooting what’s wrong with an appliance? Digging through the manuals or spending hours searching through obscure online forums to find someone with the same issue are undoubtedly frustrating activities.

You can cut out much of this frustration with both the Supreme and Classic. Each one has indicator lights on top that tell you when the coffee maker in question needs a little TLC, whether that’s a water refill or descaling.

Descaling is crucial for the health of your coffee maker. Scale buildup not only affects the taste of your coffees, but it can damage your Keurig over time. You can’t always tell when you need to do this, though, which is why it’s so helpful that these Keurigs remind you.

Removable Water Tank

The fact that the Keurig K-Supreme and K-Classic have water tanks isn’t surprising. They wouldn’t be able to perform their basic coffee brewing function without steady access to water.

What makes the water tanks so useful is the ability to detach them from the coffee maker when you need to. This results in effortless refilling and cleaning, since you don’t have to try and perform these tasks on your counter while the tanks are stuck to the Keurigs.

Pods or Coffee Grounds

You can brew your standard cup of drip coffee two ways: with your own coffee grounds or with pods. There are benefits to either method.

Pods, which contain pre-portioned coffee grounds in hundreds of flavors, are convenient. You can just choose a flavor you like and put it in your Keurig to brew a cup.

Using your own grounds, however, widens the options of blends you can brew. It also ensures your coffee is as fresh as possible.

The good news is, the Supreme and Classic are compatible with either brewing method. If want something easy and quick, just choose a K-Cup pod. On the other hand, if you want to use a specific blend of coffee not available in K-Cup form, you can purchase a reusable K-Cup compatible with your Keurig, which allows you use whichever grounds you like.


Water Tank Size

The size of a coffee maker’s water tank is crucial. Larger water tanks can brew more cups of coffee before you need to pause and add more water.

In that regard, the K-Supreme beats the competition. Its 66-ounce water tank is almost 20 ounces larger than the Classic’s, which can hold up to 48 ounces.

This means the Supreme can make a couple more drinks than the Classic can. If you’re the only person using it, this may not matter. However, if you’re preparing drinks for multiple people, you might appreciate being able to go longer without refills.

Drink Sizes

Let’s be clear: both these Keurigs can brew drinks in multiple sizes. The one difference is that the Supreme has an additional size, whereas the Classic is limited to three different sizes.

On the Classic, you can brew 6, 8, and 10-ounce cups. The Supreme gives you one extra size: 12 ounces. This might not be a dealbreaker for you, but if you’re the type of person who really likes their java, you might want a larger cup instead of having to brew a couple smaller ones to satisfy you.

Available Colors

Earlier on in this post, we mentioned that you can get either the Supreme or Classic in two colors. The two available colors for either coffee maker are different depending on which one you choose, though.

The K-Classic is available in either black or rhubarb. On the other hand, you can get the K-Supreme in black or gray.

This isn’t going to be a big deal for most coffee lovers, but it may be important to you if you want your Keurig to match with your décor.

Keurig K-Supreme MultiStream Technology

Frequent patrons of coffee shops get spoiled by the quality of their coffee. Drinking anything from a homemade coffee maker can pale in comparison.

The K-Supreme works to make you a boldly flavored cup each time with its new multistream technology. In short, what it does is extract more from your coffee grounds.

Multistream technology is fairly self-explanatory. Instead of using just one stream of water to extract your coffee, the Supreme uses multiple, ensuring you get the most from every cup.

Keurig K-Supreme Multi-Position Water Tank

One aspect that makes the Supreme so unique is its adjustable water tank. For most coffee makers, the water tank is stuck in one solid location. This means you’re limited in where you can put the coffee maker.

With the K-Supreme, you get much more flexibility. Its water tank can be swiveled behind the machine or to the side, which expands the options on where you can put it.

Got a packed countertop? Pivot the tank behind the Supreme to create a narrower profile that can slide in between appliances. On the other hand, you can move the tank to the side if your counters are on the shallow side.

Keurig K-Supreme Iced Coffee Setting

Want to make a cool and invigorating cup of iced coffee? With the Keurig K-Supreme, it’s easy.

Add some ice cubes to your coffee cup before brewing and then push the Iced button on top. The Supreme will brew over your ice without filling your cup too much.

Which One Should You Choose?

At the end of the day, which of these Keurigs should you choose? The answer to that question lies with you and your specific needs.

We think the main reason you would pick the K-Classic in this comparison is that it tends to be affordable. Those who are on a budget might find it preferable for that reason.

The other reason you might want the K-Classic is if you find its colors more desirable. It comes in an optional rhubarb color that would add a cheery splash of color to any kitchen.

However, in most other aspects, the K-Supreme is the victor in this comparison. For starters, it can brew more drink sizes than the Classic can. The extra-large 12-ounce drink size could be a draw to dedicated coffee drinkers.

If you’re looking for a stronger coffee taste from your Keurig, the Supreme is the better choice, as well. Its multistream design ensures each cup undergoes a balanced extraction.

Additionally, the Supreme is a great pick for anyone with little room to spare. By moving the water tank, you can tweak the shape of the coffee maker and make it more suitable for different areas.

Here’s our advice:

Go with the Keurig K-Supreme if it’s within your budget and you want the boldest coffee you can get from a Keurig.

If you need a more budget-friendly Keurig, the Keurig K-Classic could be the better choice for you. It’s also what you should choose if you want the rhubarb color.
