By Arthur McMahon ⋅ Review Editor ⋅ Updated September 16, 2025
For those who don't want a 10-step coffee morning routine, a Keurig coffee maker is the perfect solution for keeping it simple.
We tested the top 10 Keurigs side-by-side, evaluating their performance in brewing a tasty cup of coffee, consistency, brewing speed, customizable features, and ease of use and cleaning.
The best Keurig we tested is the Keurig K-Supreme. This unit brews outstandingly delicious coffee that's straightforward and fast to make. Our panel of testers found it brews consistent, neutral flavors across multiple cups.
If your budget falls under $100 and you want the simplest experience, and you don't mind a light-tasting brew, we recommend the more affordable Keurig K-Mini.
Editor's Note: This Keurig review was updated on September 16th, 2025, with fresh taste-testing results from our new Keurig machines and old favorites.
The cups brewed from the Keurig K-Supreme were among the most delicious across our testing, according to our team of taste testers. Nutty and sweet coffee notes were identified by several of the tasters. Lead Tester Arthur McMahon reported that this brewer produced “…a robust cup of coffee. This machine pulled out the full flavor of the beans.” Tester Katherine Best-Shaw said her drink was “solid” and “very balanced.” The K-Supreme was consistent, too, with multiple cups across several brew cycles tasting nearly indistinguishable from one another.
While the coffee tasted great, there's so much more to be said about why the K-Supreme is our top choice for most coffee drinkers. For one, it's a remarkably consistent machine, scoring almost perfect across the board regarding the temperature and volume of each cup produced. And, in fact, it was perfectly consistent in brew time—recording exactly 1 minute 4 seconds for each cup brewed, which is quite fast. Plus, it was super quick to power on for getting that first cup started as well at 1 minute 14 seconds (only the Keurig K-Express and Keurig K-Slim were faster to power on and brew a first cup from a cold start).
The K-Supreme interface is very intuitive and simple to understand, even at first glance. Every button's purpose is crystal clear. The water reservoir is fairly large, but easy to maneuver thanks to its handy handle. What's more, cleaning and maintenance are a breeze. This is a tidy machine with minimal splashing and a matte surface that doesn't easily show fingerprints or other marks. And, it's relatively compact given what it can do, making it a fine choice for virtually any size of countertop.

That said, no machine is perfect. While the K-Supreme is fantastic at all that it does, it's not the most feature-rich machine. This Keurig coffee maker has a nifty auto-on feature, a brew over ice function, and a high-altitude setting. But, it's missing some options found on other Keurigs, such as an auto-off feature and precision temperature control. It does offer four different cup sizes for brewing, but other models like the K-Elite and K-Supreme Plus Smart offer five options. It also brewed, on average, a smaller cup of coffee than most of the other machines we tested, with an 8-ounce cup weighing in at 212 grams for the K-Supreme. For comparison, an 8-ounce pour from the Keurig K-Classic weighed 225 grams on average, which was about the middle of the pack. Still, gram for gram, you're getting more flavorful and richer coffee with the K-Supreme than from most other Keurigs.
The Keurig K-Supreme Plus Smart produced our taste-testing team's favorite coffee with strong yet smooth flavors. Taster Max Wendel said, “I think this is the best, most full coffee flavor from start to finish.” Likewise, tester Laurel Hamers said, “This is my favorite Keurig cup,” and Katherine noted that it had a “refined taste” to it. Fruity, chocolately, and hazelnut flavors were the most prevalent, and our team also found the mouthfeel to be very pleasing, coating their tongues briefly with lucious coffee flavors before washing away with a satisfying finish.
The Keurig K-Supreme Plus Smart has excellent features that make it a highly adjustable machine, which is also simple and intuitive to use. There are six temperature settings, five brew sizes, and an iced coffee option. Users can also choose their desired coffee strength or use the “BrewID” function, which scans the inserted K-Cup and automatically adjusts the strength and temperature settings based on the manufacturer's recommendation. This smart brewer also detected our reusable K-Cups and saved this information to be used again. The Keurig app lets users start the machine remotely, schedule their caffeine intake, or adjust brew settings. It also includes step-by-step recipes and automates pod deliveries. In short, it's incredibly adjustable to your personal preferences and has many features that make it undeniably convenient. And yes, its brew quality is precise and consistent, and it's a cinch to clean and maintain, just like the K-Supreme.

Although it topped most of our tests, we didn't select the K-Supreme Plus Smart as our top choice for most coffee drinkers for a couple of reasons, one being the price. It's expensive, more so than perhaps a Keurig should be, and the standard K-Supreme is competitive with its smart sibling at a much lower price point. And, while the app and smart functions enable a wide range of digital conveniences, it can be cumbersome at times, even for those who are technically inclined. The initial setup of the K-Supreme Plus Smart isn't as streamlined as we hoped, and it takes a bit of time and effort to connect to the app. Once connected, it works great, generally, but the smart features (such as the machine's BrewID process, which identifies the inserted K-Cup) can cause delays. Other alerts on the LCD screen (like software updates or notifications) also create a delay in the brew process. That's why we think most will be happier with non-smart Keurigs like the standard Supreme or K-Duo. That said, we think this is the best-tasting coffee of the bunch, and if taste matters to you and price doesn't, this is the Keurig to buy.
Unsurprisingly, the Keurig K-Mini didn't tickle the palates of our taste testers as pleasantly as the larger and more capable Keurig machines, but it had some notable highlights. Overall, our team found the coffee flavor and mouthfeel to be both light and balanced, with nutty, stale wood, and bitter flavors more prominent than any others. The acidity was on the mellow side of bright, which is a marked improvement over many of the other smaller-sized Keurigs we tested, which were comparably dull. On that note, referring to other mini-sized Keurigs, tester Gabriela Norton said the K-Mini's coffee, “had more flavor than previous machines.” McMahon pointed out that the Mini's brew was “surprisingly palatable” and went on to say, “the coffee is balanced, though not many flavors poke through. It's not unpleasant.” Acceptable, inoffensive coffee is about the best you can hope for from any budget coffee machine, and the K-Mini hit that mark.
Two benefits stand out as the top selling points of the K-Mini—its budget-friendly price and its compact size, making it ideal for studio apartments, camper trailers, and dorm rooms. Given its unintrusive design, this machine can easily be stored in a cabinet after every use rather than left on the countertop permanently. We also like that it's ridiculously simple to use due to its quick, three-step process: Pour the amount of water you want your drink into the reservoir, place a K-Cup in the machine, and hit the large K button to start the brew cycle. The Mini proved to be shockingly consistent in flavor and liquid volume across multiple rounds of brewing, standing toe-to-toe with much more expensive machines. And it's available in several fun colors.

The K-Mini's simplicity might be a drawback for anyone who enjoys customizing their brews. Most Keurig machines let you select your cup size and brew strength with the touch of a button. With this machine, you must decide how much water to pour into the 12-ounce tank every time you want to brew, and that's the amount of coffee you'll get—not ideal for those who want a huge cup of coffee in the morning. And there are no controls for strength or temperature. There are other compact Keurig options out there that offer more features and have large water reservoirs, such as the K-Iced and K-Express, though they're not quite as small or wallet-friendly. The Mini also didn't wow us with its coffee flavor and quality. Though the coffee was drinkable, you'd have to step up to a full-size Keurig like the K-Supreme to get a substantial boost in flavor and overall coffee quality.
The Keurig K-Elite produced balanced, neutral cups of coffee that didn't stand out much, one way or the other. “This is as neutral as coffee could taste—no bad notes,” said Wendel. This rang true across the board. The aftertaste and acidity levels were also described as neutral and smooth by testers. “I would drink this again,” said Katherine. “It's a little weak, but overall a decent cup of coffee.” One tester noted that it was “like an inoffensive diner coffee.” As the tasting team searched for flavors on their taste buds, “woody” was the only common descriptor uttered. Otherwise, it was simply fine and neutral, which means the K-Elite tones down any potential harshness or bitterness, but didn't fully express any particular flavor notes from the coffee beans we ground and brewed.
There are a few reasons why the K-Elite would be a good choice for an office or any other setting where cups of coffee are brewed one after another. The neutral coffee flavor is a good middle ground among a bevvy of preferences. It also houses a huge 75-ounce water reservoir (the second largest in our lineup after the K-Supreme Plus Smart), which means it can be filled less often. It also has 5 cup sizes to choose from, coffee strength control, and a coffee over ice button—providing options for folks to fine-tune their preferred brew. And it's amazingly fast at brewing at 51 seconds per cup in our testing. It also has a lovely interface that is easy to figure out yet offers plenty of customization. And it's not messy in the least, so you won't have to worry about countertop splashes or cleaning the machine daily beyond a quick rinse of its removable parts like the drip tray.

It has a few downsides, but none of them are earth-shattering. The most inconvenient part about the K-Elite is that it takes a few minutes before you can get your first cup. If you've ever used a K-Classic, then you'd be familiar with the warm-up time needed. From powering on the machine to completing the brew of the first cup, we recorded 2 minutes and 55 seconds. That's because this machine takes in water and heats it up before beginning the brewing process, while other Keurig machines like the K-Supreme or K-Mini heat the water instantly as it is brewed. This means the K-Elite is a bit slow to make its first cup, but, because of this process, it is one of the fastest to brew cups 2, 3, 4, and so on. Otherwise, the machine is a bit bulky, which means it's probably not the best choice for small spaces, and it is among the more expensive machines we tested.
Our testing team thought the K-Cup coffee the Keurig K-Duo Hot & Iced Gen 2 produced was light on body and flavor with a mix of sweet, bitter, and ashy tasting notes peeking through. “I think this is a nice, standard cup of coffee,” said taste tester Wendel. On the other hand, Gabriela noted that “there wasn't a lot of body to the coffee,” and Laurel had similar thoughts, saying the brew was “weaker than I prefer.” Overall, the reviews were mixed, but the coffee's light taste and mouthfeel were consistent.
Loaded with great features that are well laid out and easy to decipher thanks to a highly intuitive interface, the K-Duo is a wonderful multi-use coffee machine with lots going for it. It has a clear, bright, and easy-to-read display screen with a clock, and the buttons themselves light up as you use them, which helps keep track of the selections you've made for your next brew. Settings include extra hot, extra strong, or choose the brew over ice setting. And, it has a high-altitude setting designed to adjust brewing to compensate for lower atmospheric pressure at higher elevations. And what makes it an exceptionally versatile machine is that you can drip brew an entire carafe of coffee. In essence, it's two coffee machines in one. The drip brewer even has an auto brew feature, just like a good standalone drip brewer machine would have. The Duo faced stiff competition for our versatility pick with the Keurig K-Cafe, which can pull shots and foam milk for lattes and cappuccinos, but ultimately the K-Duo proved to have more useful features and produced tastier K-Cup brews.

Though the K-Duo can do many things, it's a jack-of-all-trades and master of none. The coffee flavor was good but not great—same story with the brew quality and consistency. The brew times and temps had a bit of variability, which resulted in a touch of flavor inconsistency as well across multiple cups. The results weren't bad, but they weren't great either. In our testing, it took 1 minute 21 seconds for us to brew our first cup, which isn't slow, but machines like the K-Supreme and K-Slim were faster. The reservoir is large, which is nice, but it's completely tucked away in the back of the machine, so you can't see its current water level without leaning around to the side. Among the machines we tested, the K-Duo has the longest descaling time at 75 minutes every three months.
If you want a Keurig that can batch make multiple cups of coffee or just one from a single pod, this is a great option. It also allows users to adjust the temperature of the brew for serving up iced coffee.

How We Tested
We purchased and tested the 10 best Keurig coffee makers to determine which Keurig was the best of the bunch. To do this, we laid out an in-depth testing plan to analyze each product across multiple kitchen tests. We tested how well each machine could make a cup of coffee, how good that coffee tasted, and how fast and consistent it was at brewing. We also considered the number and usefulness of the features it came equipped with, the drink customization options available, how easy it was to use, its size, and how much effort it took to clean and maintain the machine.
All in all, our Keurig coffee maker tests focused on six primary rating metrics:
Taste (45% of overall score weighting)
Brew Quality (15% weighting)
Brew Speed (15% weighting)
Customization (10% weighting)
Ease of Use (10% weighting)
Cleaning and Maintenance (5% weighting)
We ran each Keurig coffee maker through a gauntlet of tests to grade them on taste, brew quality, speed, customization, ease of use, cleaning, and maintenance.

Analysis and Test Results
A good cup of coffee has become an essential part of the morning routine for many. To make yours the best it can be, we thoroughly examined each Keurig coffee maker, noting each model's strengths and weaknesses. We conducted a tasting panel to see which machine made the tastiest brews, and also focused on brewing consistency while making several cups of coffee in a row. We carefully considered each model's ease of use, its customizable features, and its cleaning and maintenance requirements.
Worse Value
Better Value
What's the Best Value?
If you're in the market for a Keurig, you probably value convenience. The Keurig K-Supreme Plus Smart is one of the brand's most exceptional products, but it comes with a premium price tag relative to other Keurigs. Of course, there are many coffee makers that cost much more, and many that cost less.
If you're shopping on a tight budget, the Keurig K-Mini is a straightforward, inexpensive machine that will work for those willing to forego adjustable features or strong, bold coffee. Its minimalist design might be intriguing to some. The K-Classic also offers a simple design in different ways, but includes a few basic features that the Mini lacks.
We found that more expensive options usually offer more features. If you're looking for ultimate adjustability and customization, it is worth shelling out the extra cash for one of these machines, like the K-Supreme, which can often be found on sale. These machines also tend to brew more flavorful coffee, thanks to more consistent brewing processes.
Tips to Save Money in the Long Run
The price of a Keurig coffee maker can be deceptive. To use one, you need a steady supply of K-Cups, and they're much more expensive than just buying coffee beans or grounds alone. However, reusable K-Cups are available, allowing you to fill them with your own ground coffee and rinse them out once you're done. These are what we used for our testing, and they're a much better value.
Alternatively, other single-serve coffee makers cost less initially and are less expensive to own over time. The Hamilton Beach The Scoop, for example, has a lower price than many of the top-ranked K-machines and comes with a reusable filter that works a lot like a K-Cup, for less.
The simple and supremely packable AeroPress is less expensive still. To use it, you just need to add grounds, boil and pour water, stir, and press. And, it delivers some of the best-tasting coffee we've tried.
Perhaps the most economical option of all is the basic pour-over. Even high-end pour-over coffee makers cost less than $30. While there is a learning curve to coaxing the highest-quality brew out of these simple cones, we think the high-quality taste is worth the added effort. The Hario V60 Dripper is a classic example. We haven't found a better one.
The K-Mini put up impressive results given its incredibly low price point, making it an unbeatable value as a Keurig coffee maker.

Taste
In our taste tests, we sought crave-worthy flavor notes like chocolate, hazelnut, and citrus brewed from our medium-roast Verve Seabright Coffee. We put together a panel of taste testers to rate the coffee brewed by each Keurig machine in our lineup.

The team sampled coffee from each of the Keurigs we tested and rated each on its overall flavor as well as its finish, mouthfeel, and acidity. The K-Supreme Plus Smart was the clear victor regarding taste. Our testers easily identified lush, chocolatey, and nutty flavors highlighted with citrus fruit. Multiple tasters said it was “the best” and their favorite.
With the Plus Smart, users can also choose from five different brew strength options to customize the coffee, ranging from “Balanced” to “Intense”. It's worth noting that the K-Supreme Plus Smart's BrewID technology identifies the K-Cup you're using (even if it's reusable) and adjusts its brew process for that particular pod. It learns brew preferences and receives software updates that may change and enhance its ability to extract flavors over time.
Our tasting team sampled coffees from each Keurig brewer, recording their notes on the taste, acidity, mouthfeel, and finish. The Supreme models produced the tastiest results.

The standard K-Supreme was the only close runner-up. It had a more balanced flavor and produced brews that were less acidic than the Plus, with the majority of testers noting how smooth the brew was. Of the K-Supreme, taster Wendel said, “I like this one. The coffee flavor is mild, but the mouthfeel is buttery and creamy.” The K-Elite was also exceptionally neutral and balanced. This sentiment was shared among the rest of the testing team.
We tasted brews from every Keurig model using the same coffee in each and compared them against each other.

While we didn't find anything wrong with the coffee brewed by the K-Duo and K-Classic, it didn't stand out. The coffee is otherwise “inoffensive”, as was the K-Mini's brew, which turned out better than expected given its diminutive size and low price point. A touch of cream and sugar would go a long way with these models.
Our expert taste testers found that the premium Keurig K-Supreme Plus Smart brewed the best-tasting coffee.

Brew Quality
To test each Keurig's brew quality, we aimed to measure how consistent it was over the course of three brew cycles. So, for each coffee maker across three cups of fresh-brewed coffee, we recorded the highest temperature reached as the coffee dripped down a thermometer into the cup, then measured the liquid volume of each cup and tared out the glass it was in. Again, we tasted each coffee to score the consistency of its taste.
The Plus Smart was just about perfect across all tests, consistently producing a full cup of coffee that always tasted exactly the same. The standard K-Supreme had slightly inconsistent liquid volume and taste —it got a bit more acidic with each progressive cup, but the difference was slight.
Keurig K-MiniKeurig K-Supreme Plus Smart
Machines like the K-Mini consistently produced lighter brews, while the K-Supreme Plus Smart consistently brewed deliciously neutral and flavorful coffee.
The K-Classic and K-Elite have perfect taste consistency, both of which are more in line with the classic Keurig styling and brew design. That is, both of these machines take a couple of minutes to fully power on, pull water into the machine, and heat up before the brew process actually begins. This is likely why they were more consistent than most of the rest, which are newer Keurig designs that focus more on speed. The volume of the coffee produced was off by a couple of grams, but this is very minor.
Our tests proved that some Keurigs are more consistent than others, with the most consistent in terms of taste and volume being the Keurig K-Supreme Plus Smart.
The K-Mini outperformed its small-sized Keurig competitors in terms of liquid volume and taste consistency, and regularly produced 7.7 ounces of coffee after brewing three servings back to back. The K-Duo also put up some respectable numbers across the board.
We found that all of the Keurig coffee makers brewed at an acceptable average range between 180 and 190 degrees, but some definitely brewed hotter than others. The K-Cafe produced the steamiest cup of coffee of the lot with an average high temp of 190 degrees. Many of these machines do have temperature controls and various brew options that could affect the brew temperature, but we recorded our temps at the standard setting for an 8-ounce cup of coffee.
Again, the K-Supreme and Supreme Plus Smart Keurigs had the best consistency and brew quality.

Brew Speed
For this test, we used a stopwatch to time from the moment the machine turned on to when the brew cycle completed. Because the brew process can speed up or slow down when brewing back-to-back cups, we also made three cups one after another with each machine, timing how long each took and calculating the average.
In this test, the K-Express lived up to its name. It was the fastest when brewing just one cup from start to finish (1 minute and 9 seconds) and has one of the quickest average brew times across the three brew cycles. To put that in perspective, the Keurig K-Elite took around three minutes for its first brew cycle because of how long it takes to warm up. That's a lot of extra wasted time for a coffee maker designed for efficiency.
Above you can see the time it took from pushing the start button to the last drip of coffee.
The K-Supreme and K-Slim had equally fast average brew times at 1 minute and 4 seconds, but were a few seconds slower when brewing the first cup from a powered-off state.
We calculated the average brew time across three trials. The figures above do not include the start or warmup time.
Interestingly, the K-Cafe, K-Classic, and K-Elite were wicked fast at brewing multiple cups of coffee once they had the chance to warm up, brewing at an average of 41, 43, and 51 seconds to brew on average. They all draw in water before the brew process begins, which gives them a jump start once they've been given that time to heat up. However, all three took more than a minute longer than the rest of the competition to warm up.
And the K-Supreme Plus Smart was almost fast enough to compete with the quickest machines, but the smart BrewID functionality and LCD screen notifications added several seconds of lag to the otherwise optimized brew process, slowing it down to 1 minute and 21 seconds from start to finish. Though that's still pretty fast.
The K-Mini may have been one of the slowest, but it still managed to brew a cup relatively fast compared to a standard drip brewer.

Customization
To score customization, we examined the features each Keurig came equipped with, cup sizes, and how many colors the Keurig came in, but gave the most weight to the available features and brew adjustability options. The K-Supreme Plus Smart is far and away the most customizable machine we tested.
The K-Supreme Smart allows users to choose from five cup sizes and brew at five different coffee strength levels. It also has adjustable temperature control, an energy-saving auto-off feature, and more. But what makes it remarkably customizable is the smart features and companion app. You don't need the Keurig app to control the device, but it does enable you to adjust the high-altitude setting, turn the machine on or off from anywhere, save your favorite brew settings, schedule a brew, browse drink recipes, shop for K-Cups, and the list goes on.
The Keurig K-Supreme Plus Smart is abundant with customization options both on the device and via the Keurig app.

The most customizable unit without a smart app is the K-Elite, which has five cup sizes, a strong brew button, and brew-over-ice functionality. It even has a couple of neat features that the Plus Smart lacks, like a built-in clock and an auto-on function.
The K-Express has three cup sizes and a Strong brew option.

The Keurig K-Duo Hot & Iced Gen 2 also includes many of the same options as the Elite, but what really makes it stand out is that it also includes the ability to brew batches like a traditional drip machine. It comes with a full-size 12-cup carafe that you can use a filter and grounds to brew into when a K-Cup isn't enough. Likewise, the K-Cafe has bonus features, too, allowing you to pull shots from a K-Cup and froth milk for lattes and capps (though it lacks some common features and brew options).

If you're more interested in the color options rather than functions, the K-Mini has the most with five fun colors to choose from. The Elite and Supreme also offer a few options for those who want to color-coordinate their kitchen appliances.
The K-Duo has multiple ways to make your Keurig drink your own, plus you can brew an entire pot of coffee for your family or an office.

For our ease of use tests, we examined each machine's interface and graded it on its intuitiveness: Were the buttons clearly labeled? Was the brewing process easy to navigate? We also scrutinized the usability of the water reservoir, checking to see how much water it could hold, if it was easy to remove and fill, and if the water level was easy to see. Finally, we took into account the machine's size and weight to see how easy it was to store on a countertop or if it could easily fit inside a cabinet when not in use.
Generally, all of the Keurigs were relatively easy to use, especially when you compare them to the complexities of other traditional coffee makers. Still, some proved to be much more user-friendly, like the Supreme and Supreme Plus Smart, both of which have very clear and easy-to-understand interfaces, highly visible water reservoirs fitted with helpful handles, and fairly compact footprints. However, the K-Supreme Plus Smart also has smart functionality and offers advanced controls via the Keurig app. These features, such as scheduled brewing, can make this brewer easier to use. However, it requires the added effort of connecting the brewer to your WiFi network and installing the app.
While the smart features and app are helpful on the K-Supreme Plus Smart, you can't brew when certain smart tasks are underway.
The K-Duo has the best interface of them all, with clear, front-facing buttons that light up when pressed and are supported by an informative and easy-to-read LCD screen. It's rather bulky, though, so it's not as easy to store away.

The K-Elite is another incredibly easy-to-use machine. It features an enormous water reservoir that's easy to remove and fill. But, the water level is not visible from the front due to a design choice that includes an opaque panel, which enhances the design's appearance but reduces its functionality. It also has an intuitive interface with tactile buttons and a helpful LCD screen.
The K-Classic doesn't have many features, but the user interface is simple and easy to understand with clear buttons and indicator lights.

Cleaning and Maintenance
We inspected each brewer to see how much it splashed while brewing our coffee. We also meticulously cleaned each machine, including the reservoir, drip tray, and K-Cup housing. We deducted points if the components aren't dishwasher safe or the unit easily collects fingerprints. Plus, we checked to see how often each needs to be descaled, if there is a cleaning reminder/indicator, and how long and involved the process is.
The Keurig K-Supreme has a faster descaling process at just 20 minutes, but needs to be cleaned every few months.

Descaling your coffee maker is necessary to ensure optimal coffee flavor over the life of the brewer, as well as to extend its life as long as possible. Some Keurigs only require about 20 minutes of investment every three to six months for descaling, which includes the K-Iced, K-Supreme, K-Express, K-Slim, and K-Supreme Plus Smart. Others could take as long as 45 to 75 minutes to complete the descaling process, like the Keurig K-Mini and Keurig K-Duo Hot & Iced Gen 2.
A few machines, like the K-Express, allow grounds to escape the K-Cup, meaning this unit requires frequent wipe-downs on the inside.

In general, the Keurigs we tested were pretty tidy, with a few exceptions. Splashes were minimal overall. The Plus Smart was the cleanest of the bunch and required the least amount of effort to scrub or wipe clean on a daily basis. Others like the K-Supreme and K-Duo were very tidy as well, but these both have thin and tall water reservoirs that are difficult to get deep into and scrub clean.
How to Choose a Keurig Coffee Maker
Ultimately, to choose the right Keurig coffee maker for your needs, you must determine exactly what it is you want from the machine. Consider the following questions:
Where will I store my Keurig coffee maker?
What size do I want my cups of coffee to be?
Do I want to make iced coffee in addition to hot coffee?
Will people other than myself use this Keurig, and if so, what are their coffee preferences?
Knowing the answers to these questions will help solidify the size of the Keurig you can store, as well as the features and adjustment controls you desire. Once you have this basic understanding, consider the following variables.
Size
You don't want to purchase a Keurig that doesn't fit on your countertop. Measure the dimensions of the space where you intend to keep your Keurig, and check that against the dimensions of the Keurig machine itself. Be mindful of how you will use the machine as well. While the dimensions may technically fit in your intended space, you'll also be opening and closing the Keurig regularly and removing and filling the water reservoir, so check how low your cabinets hang and make sure you have some extra vertical space. Are there front-facing controls and screens, or are they located on the top of the machine? That could also make a difference in how you interact with the machine every day.

On the other hand, you may not want to go too small, either. Smaller Keurigs have much smaller water reservoirs that will need to be filled more often. If you have a family of Keurig coffee drinkers or are considering a Keurig for an office, you'll want a larger machine with a larger reservoir that can handle multiple drinks before needing to be refilled.
Though not as small as the K-Mini, the K-Express is a compact machine that can fit well even on small countertops.

Versatility vs. Simplicity
Some people may have a single coffee setting that they stick to day after day, while others like to change up their caffeine consumption. Some Keurig coffee machines have super simple interfaces without many features or customization controls, while others offer a plethora of drink customization options. Identifying the features and controls you want most will help whittle down your options. And don't forget to consider who else may use the machine—what options do they need to make the coffee they desire?

Taste
Coffee is worth celebrating—good-tasting coffee even more so. Our testing shows that every model of Keurig coffee maker brews coffee in a unique way, resulting in wholly different coffee taste experiences. Even when brewing the exact same coffee. Using our taste notes and ratings, look for a machine that meets your other needs while also producing a flavorful brew you'll look forward to every morning.
Coffee taste quality is vital for many of us, but if you're someone who prefers a splash of coffee in your cream and sugar, you may want to consider looking more at Brew Speed and bonus features.

Price
Budget constraints may be a factor. This is why considering all of the other options first is vital—knowing what you want will help you identify the most affordable Keurig that meets your specific criteria. Keurigs usually cost between $100-$200, with very few options under $100. If you're looking to spend less than a hundred, a French press or pour-over may be better options.
Less expensive Keurigs may not necessarily be “worse” than more expensive models, but they likely have fewer features and are smaller in size. That doesn't mean they can't make a great cup of joe, though.

Conclusion
Keurig coffee makers make coffee without much time or hassle. They're the ultimate coffee appliance for convenience. Using the right brewer can easily become a joyful part of your morning routine. We hope our in-depth review has helped you decide on a new coffee maker based on your preferences and needs.
Keurig has many competitors in the single-cup and pod-coffee markets, and Nespresso models consistently outperform K-Cups in our tests. But, while Nespresso tends to produce a richer-tasting cup, both machines require expensive pods and produce waste that can be a nuisance to recycle properly. You can invest in refillable pods, but then you're basically making drip coffee. And, as K-Cup inventor John Sylvan told The Atlantic, “It's not like drip coffee is tough to make.”
