Best Keurig Coffee Maker in 2021 – Top 9 Reviews And Buying Guide

Do you find yourself waiting for your morning coffee for way too long?

Chances are, you’ve heard of Keurig—but there are so many versions, options, and special features on each one that it can be difficult to find the best Keurig coffee machine for your needs.

From the latest Keurig model, K-Supreme Plus SMART, to the original K-Classic Coffee Maker, we’ve rounded up the best Keurig coffee makers so you can find your perfect brew.

Whether you’re looking for an at-home coffee maker or one for the office, Keurig has you covered.

What Is Keurig?

A Keurig machine is a single-serve coffee maker that uses Keurig K cups instead of traditional coffee grounds. Keurig machines range from slim and ergonomic to complex two-in-one coffee makers with the Keurig single-serve maker and a regular coffee pot attached.

Using a Keurig means no more messy filters, measuring, or grinding your coffee beans. It also means that your coffee-making process will be sustainable, as the pods are recyclable.

Keurig is the eighth biggest food and beverage company in the United States, a study in 2019 revealed that around 42% of American households own a single-serve coffee maker. [1]

So, what makes them so popular? Keurig coffee machines are: 

  • Affordable
  • Easy to clean and operate
  • A wide range of K-cup pods available
  • Brew Coffee in less than a minute
  • Perfect for families as everyone can choose their favorite coffee

Common Features of Keurig Machines

Almost all Keurig machines have the same basic features and mechanisms. 

The most-loved feature of the Keurig K-cup coffee maker? Brewing time. Most Keurig coffee makers can brew your cup of coffee in under 2 minutes. 

K-Cup pods are another feature. You can only use K-Cups with your Keurig. However, they come in an abundance of flavors, options, and brands—so you’re never limited. Even kids too young for coffee can use a Keurig, too, as hot cocoa, hot chocolate and tea are available in Keurig pods.

Each Keurig comes with a removable drip tray for easy cleaning and to fit travel mugs.

Auto-off is another feature of almost all Keurigs and one of the most useful. If the Keurig is dormant for a while (most Keurigs allow you to program how long), it turns off automatically to conserve energy.

If you want the freshest technology in the single-serve coffee world, the Keurig K-Supreme is for you. 

This coffee maker introduces MultiStream Technology. With this method, multiple streams of water deposit into the Keurig pod—so flavor and aroma are maximized and saturated.

MultiStream Technology can give any brew more flavor than the previous Keurig coffee brewers that use only one needle to puncture the K-cup pod.

A much-requested feature of the Keurig K-Supreme model is its iced option. Now, you have the choice to make your favorite iced drinks—it’s like having your local coffee shop right at home! 

The quiet brew technology also reduces the noise during the brewing process.

This new K-Supreme line comes in three separate models: the K-Supreme base model, the K-Supreme Plus, and the K-Supreme Plus Smart

  • Works with Keurig App

If you’re looking for temperature and strength control, the K-Supreme Plus and K-Supreme Plus Smart are your best bet. If you don’t want those extra features, you would enjoy your morning cup made by the basic K-Supreme.

This Keurig pod coffee maker is one of the most versatile in the Keurig product lineup and is a hit among customers. 

The K-Elite machine is versatile and programmable, giving you the best of both worlds. You don’t have to sacrifice the latest technology to get a lower price. Surprisingly, the Keurig K-Elite shares several characteristics with the K-Supreme Plus models except for the MultiStream technology.

It also comes with temperature control and lets you brew over ice or select a strong brew flavor. K-Elite is one of the fastest Keurig brewers, it takes less than 1 minute to brew a cup of coffee.

Auto-on is a popular feature for busy families. Gone are the days of getting ready for the day and forgetting to make coffee—or cutting into valuable time waiting for the coffee maker. 

The Keurig K-Elite is the brand’s best-seller. It received thousands of positive reviews from coffee enthusiasts everywhere.

Want the original Keurig? The K-Classic is your new best friend. 

This coffee maker is the machine that started it all—the K-Cup craze, accessible, in-home delicious coffee, and affordable options. 

The classic Keurig has: 

  • One minute or less brewing time
  • Programmable auto-off
  • 3 cup sizes
  • Indicator lights

The Keurig K-Classic is perfect for you if you want something that is not too flashy but still makes good coffee. 

But, if you’re looking for something snazzier, you may want to upgrade to the K-Supreme or K-Elite to get all of the bells and whistles. 

This machine also does not have strength and temperature control, and only offers 3 cup sizes. So if that’s important to you, it might be worth skipping and splurging on the latest model. 

Your next coffee maker doesn’t have to be expensive. The Keurig K-Classic is more budget-friendly than the two machines listed above.

Have you ever wanted a coffee maker to take on the go? This Keurig machine can do just that. 

Advertised as their slimmest design, the Keurig K-Mini is under five inches across. Perfect for students, offices, and traveling! 

You can take the K-Mini anywhere. As long as you have a power source, you can make your favorite drinks. 

Other features of the Keurig K-Mini are: 

  • One cup reservoir—you have to use fresh water every time
  • Auto-Off kicks in 90 seconds after your last cup
  • Cord storage means no messy wires or cluttered counters
  • Bright colors add life to any room

The K-Mini is a prominent option if you have very little counter space and need something compact—but still want a delicious cup of coffee.

Also of note is the K-Mini Plus, which has features like strength control, a removable water reservoir, and pod storage with purchase.

Sister to the K-Mini, the K-Slim is a slightly advanced (but still compact!) coffee maker. 

The K-Slim maintains the under-five inches width but adds depth with a 46 oz reservoir—so no need to add fresh water with every use. 

A few other differences between the two compact makers are: 

  • K-Slim is large enough to accommodate travel mugs
  • K-Slim has a high-altitude setting
  • Reservoir is removable

K-Slim is ideal for minimal counter space as well but has a few more features than the K-Mini. If you drink coffee twice or more a day, you’ll like the K-slim since the water reservoir capacity allows you to brew up to 4 cups.

Dual Function: Grounds and K-Cup

Not ready to let go of your coffee beans, or prefer grinding your own? Keurig has machines for that, too!

If you don’t like the idea of buying pods, you can keep using your favorite ground coffee with dual-function machines.

6. Keurig K-Duo

Keurig gives you endless possibilities with this coffee maker. You can brew an entire carafe of coffee in the classic-style coffee pot or make a single-serve cup on the traditional Keurig side.

The K-Duo: 

  • Provides a strong option for a more flavorful brew
  • Includes a glass carafe and heating plate
  • Pause and pour lets you pour a cup out of the carafe mid-brew

This machine fits coffee experts that love the traditional carafe or coffee drinkers that want more than one cup at a time. 

It’s also ideal for offices, as you can make as many cups as needed—or people can make their brews.

Like the original model, the K-Duo Plus brews both ground coffee and K-Cup pods and comes with a carafe. 

The design of the K-Duo Plus is sleek and slim—much more so than its counterpart. 

Additional features are: 

  • Stainless steel thermal carafe
  • Multi-position reservoir
  • K-Duo Plus comes with a gold mesh filter starter kit

The K-Duo Plus and the K-Duo do almost the same thing—but the Plus model is better for smaller areas and those who need a large thermal carafe.

Latte and Cappuccino

Do you consider yourself a borderline barista? The Keurig K-Cafe is for you! 

There’s nothing like a creamy latte or smooth cappuccino. This Keurig lets you make frothy drinks in your kitchen. 

The Keurig K-Cafe comes with a dishwasher-safe milk frother, so no pesky cleaning after each use. You can use whole, skim, almond, or any milk of your choice. 

Keurig does note that certain kinds of milk can affect the frothiness of your foam—lactose-free milk products, for instance, do not produce foam as well as regular or nut milk.

Of course, the K-Cafe can brew the classic Keurig pod cup of hot coffee, but there are some perks in addition to the frother: 

  • Coffee shots for specialty drinks (espresso) 
  • Cold setting for cold frothed milk
  • The strength setting for bolder brews

Whether you’re an experienced barista or just getting started in the world of cappuccino making, the K-Cafe is a fun and delicious option.

Are you searching for the best of the best? The Keurig K155 Coffee Maker might just be the one. 

This high-tech but still easy-to-use coffee machine is loaded with features so everyone in your office or home can enjoy their preferred brew. 

Some of the most elite features of this machine are: 

  • Full-color LCD screen
  • Language options for English, Spanish, and French
  • Interactive touch screen
  • Adjustable brew temperature

The K155 machine is different from the other Keurig coffee makers on this list because it’s a commercial-grade machine, meaning it’s not intended to be used by just one person. 

The materials used to make the K155 are UL certified and durable for constant use. It has a drainable hot water tank and can hold up to 90 oz of water.

Keurig states that this brewer is made for offices of 15 people or less—and to get a much bigger machine if your office has more employees.

How Does a Keurig Coffee Maker Work?

Using a Keurig is super easy and only takes a few minutes. Step-by-step instructions for the K-Classic brewer are below. 

  1. Fill the water reservoir
  2. Turn the machine on—water will begin heating automatically
  3. Place your mug on the drip tray, or remove the tray if you’re using a travel mug
  4. Lift handle and put in your K-Cup coffee pod
  5. Lower handle, select cup size and start
  6. Enjoy the freshly brewed cup of coffee in 1 minute or so.

Most Keurig K-cup coffee makers have similar instructions, although the K-Mini requires filling every time you use it. If the model has a water reservoir, you can fill it up and make cup after cup until it’s empty.

What Coffee Does a Keurig Coffee Maker Brew?

All Keurig models use K-Cups, aside from the two duo models that have carafes. There are plenty of options that aren’t coffee, too. 

A Keurig is pretty much a drip coffee maker, just with a faster stream. Keurig coffee is weaker than coffee from a drip coffee maker, so if you prefer a bolder flavor, purchase a Keurig with customization options. 

If you love espresso, you should try the Nespresso or espresso machine instead. Keurig brewers don’t make espresso.

What Coffee Pods Do Keurig Coffee Makers Use?

Keurig Coffee makers brew coffee with K Cups. A K-cup coffee pod contains pre-measured coffee grounds, which are well sealed with a foil lid. It’s a convenient and hassle-free way to brew a single cup of coffee at a time.

k-cups

There are countless flavors of K-Cup coffee pods! From Breakfast Blends to Caramel Lattes, your favorite drink awaits.

When you think about popular coffee companies or brands, what comes to mind? Starbucks, Dunkin’, illy, Lavazza, the Original Donut Shop? All of these major brands have K-Cup pods. 

Most K-Cup pods come in packs of 12-96 and range in cost. The price of K-Cups is quite affordable, you can save money in the long run if you buy a cup of coffee every day.

You can also purchase a refillable K-Cup. These are mesh cups that you fill with coffee grounds and brew like a K-Cup pod. So, if you’re obsessed with your own ground coffee, you can still enjoy it with your Keurig coffee maker.

Things to Consider When Choosing The Best Keurig Coffee Maker

If you’re still contemplating which K-Cup coffee maker to buy, don’t worry—read on to find out what specific things you should look for before you purchase your Keurig machine. 

Water Tank Capacity

Think about how many people will be using the machine. If it’s just you, and you expect to drink one cup of coffee a day, a smaller model like the K-Mini or K-Slim would make more sense. 

If you have a large family or want to purchase a coffee maker for your office, though, you’re going to want something with more water capacity. Having to refill the water reservoir constantly can get annoying and time-consuming.

Keurig water tank sizes range from 12 oz to 90 oz. 

Cup Size

Travel mugs don’t fit under all Keurig machines! If you use a travel mug often, make sure to find a Keurig machine that has enough space between the removed drip tray and the handle. 

The K-Mini fits travel mugs up to 7 inches tall. Anything larger than that is going to be a tight fit.

You should also think about the size of brew you enjoy most often. Many Keurig machines make at least three sizes (6 oz, 8 oz, 10 oz), but some make cups as small as 4 oz. 

Brew Speed

Need coffee fast, or are you okay with waiting for a few minutes? Be sure to double-check the Keurig machines you look at to make sure they meet the brew time you need. 

Keurig machines with a <1 minute brew time are: 

  • Keurig K-Elite
  • Keurig K-Classic
  • Keurig K-Select

Keep in mind that the brew time does not include the time it takes to heat the water in the reservoir. Also, brewing fast sometimes leads to watery coffee, the latest model K-Supreme brews coffee slightly slower but results in a more robust flavor. Regardless, you’ll be waiting five minutes maximum for a cup of fresh coffee.

User Interface

If you’re willing to pay a bit more, you can get a Keurig machine with a digital screen that has touch capabilities. 

Most Keurigs, though, come with no screen and just have the following buttons: 

  • Cup size selection 
  • Strength customization buttons (if included on the model)
  • On/Off
  • Flashing lights to indicate an almost-empty reservoir or need of maintenance

Some Keurigs, like the K-Duo, K-Elite, K-Supreme Plus Smart, come with a digital clock on them so you can program when you would like your coffee to brew.

keurig-user-ineterface

That said, if you have someone in your household or office who isn’t tech-savvy, you may want to stick to the standard button-pushing method to avoid confusion—especially the touch screen models.

Brew Control

Picky about your coffee? You may want to get a Keurig with more brewing customization, such as strength or temperature levels. 

The K-Mini or K-Slim models don’t give you the option to customize your cup, but the K-Elite and the K-Supreme models do. 

You should also consider the K-Supreme models if you prefer iced coffee or tea—the more basic models do not have the iced beverage option. 

The temperature customization feature on some models allows you to regulate your brew from 187 degrees to 192 degrees Fahrenheit.

Other Features

Consider what you want out of a coffee maker. Do you want a simple, everyday brew? Or are you looking to expand your coffee-making expertise with lattes and cappuccinos?

If storage is an issue for you, select a Keurig with cord storage. That way, there is no concern about your machine taking up too much space or cluttering your counter.

Some other features to think about: 

  • Movable water reservoir: Do you need to be able to move your Keurig with ease, or change the postion of the water tank for fitting your countertop?
  • Budget: How much are you willing to spend? Are you on a tight budget?

Purchasing a Keurig isn’t cheap no matter what model you buy, but there are more inexpensive options in their product range. 

Additionally, if you forget to put your coffee on a lot or you’re often rushing in the morning, you might want to get a Keurig with programmable brewing times. That way, your coffee is ready whenever you need it. 

Maintenance

Ponder how much time you’re willing to spend cleaning your Keurig. All Keurigs require some maintenance, but some are more strenuous to clean than others—for instance, a much deeper reservoir means more calcium deposits to clean. 

Needle maintenance is also crucial with all Keurigs, and it’s not a challenging process. But if you want something you’re never going to have to clean, you might not want a Keurig. Needle maintenance ensures that your coffee is free of old coffee grounds.

Sustainability

In the past, Keurig was criticized by climate activists because coffee pods are single-use plastics that end up in landfills. 

However, in 2020, Keurig Dr. Pepper began to change their practices to be more environmentally friendly. 

Keurig Dr. Pepper has a campaign called Drink Well, Do Good in which they have several goals and aspirations: 

  • Convert all packaging to 100% recyclable materials by 2025
  • Achieve 20% virgin plastic reduction by 2025
  • Use 25% post-consumer materials for packaging by 2025

Keurig Dr. Pepper’s most recent move was to change Snapple packaging to 100% recycled plastic, which resulted in a reduction of 47.5 million pounds of waste.

Climate change is another issue Keurig is fighting—they want 100% of their electricity from renewable sources by 2025. They have also reduced mileage in fleet routes, started using more climate-friendly fuels, and replacing older vehicles. 

These efforts alone have reduced their greenhouse gas emissions by 23% and their carbon monoxide emissions by 83%. 

Most K-Cup pods are recyclable in 2021, and that number is only going to increase. 

Conclusion

So, what’s the best Keurig coffee maker of 2021?

We think the best pick is the Keurig K-Supreme. We like the newer model equipped with the latest technology. We tested it and found the coffee taste better than the previous models. If you have more budget, Keurig K-Supreme Plus is also a great choice.

The K-Supreme is larger than the K-Mini, more powerful than the K-Classic, and less complex than the K-Duo, making it ideal for coffee lovers of any age.

As the latest and greatest Keurig model, the K-Supreme is bound to make your favorite brew taste even better.
