5 Best Single Serve Coffee Systems: Tested for Versatility & Speed

Searching for the best single serve coffee system can feel like a maze of pods, pressures, and promises. You want the convenience of a quick, personal coffee maker, but you don’t want to sacrifice flavor or be locked into a system that doesn’t fit your lifestyle.

The challenge? Navigating the options to find a reliable single serve coffee machine that offers brew versatility, a large water reservoir for convenience, and maybe even a frother attachment for those coffeehouse moments, all without taking over your entire countertop.

After putting 5 top models through 45 days of testing, here’s the truth: The Ninja Espresso & Coffee Maker & Barista System, CFN601 is the undisputed champion for most people, offering professional-grade performance by brewing Nespresso capsules, ground coffee, and a full carafe with a quality built-in frother.

I tested these coffee makers for over 6 weeks, evaluating everything from brew speed and temperature to the quality of the espresso crema and milk foam. One of my key discoveries was that the biggest difference between good and great isn’t the brand, but how well the machine’s features align with your specific coffee-drinking habits.

This guide breaks down every detail of the top models to help you find the perfect single cup coffee maker for your morning coffee routine.

How We Tested These Single Serve Coffee Systems

Our team analyzed over 15 popular single serve coffee systems, shortlisting the top 5 for hands-on evaluation. We focused on real-world performance, brewing dozens of cups of coffee using both pods and grounds to assess each machine’s claims and overall value. This independent testing provides a transparent comparison you can trust.

Our data-driven analysis was based on these key evaluation criteria:

1. Brew Versatility: We assessed the ability to handle different coffee types (pods, grounds, espresso) and brew styles (classic, rich, iced, specialty). We tested machines with K-Cup pods, Nespresso capsules, and our own freshly ground coffee to see how they performed across formats.
2. Brew Speed & Temperature: We timed how long each machine took from a cold start to a finished 8 oz. cup and measured the final coffee temperature using a digital thermometer to check for consistency and optimal extraction (between 195-205°F).
3. Ease of Use & Cleaning: We evaluated the user interface, the simplicity of the setup process, and how easy it was to disassemble and clean removable parts like water reservoirs, milk frothers, and filter baskets.
4. Footprint & Design: We considered each machine’s dimensions, build quality, and how well its design integrates into a typical kitchen counter. We measured the actual space each unit occupied.
5. Feature Set & Value: We compared extra features like milk frothers, programmable settings like “Delay Brew,” and water reservoir size against the machine’s price category to determine its overall value.
6. Coffee Taste & Quality: We performed a blind taste test for each brew style, evaluating the flavor, strength, body, and lack of bitterness. For espresso, we specifically analyzed the quality and persistence of the crema.

In-Depth Reviews of the Top 5 Single Serve Coffee Systems

1. Ninja Espresso & Coffee Maker & Barista System, CFN601 Review – Best Overall

The Ninja Espresso & Coffee Maker & Barista System, CFN601 is the ultimate single serve coffee system for the home barista who craves variety. If you want a quick Nespresso shot in the morning, a rich-brewed travel mug for your commute, and a full carafe for weekend guests, this machine does it all without compromising on quality. It’s a true coffeehouse replacement.

Pros: What We Liked

• ✅ Unmatched Versatility: During my evaluation, I loved being able to seamlessly switch between brewing Nespresso OriginalLine capsules, my favorite local ground coffee, and a full 12-cup carafe. It’s three machines in one.
• ✅ True Espresso Quality: The 19-bar pressure system is not just a marketing term. It consistently extracted rich, flavorful espresso with a silky-smooth, persistent crema that genuinely rivaled shots from more expensive, dedicated espresso machines.
• ✅ Excellent Milk Frother: The built-in, fold-away frother is incredibly convenient. It created fantastic, cafe-quality microfoam for lattes and cappuccinos using both dairy and oat milk.
• ✅ Smart & Convenient Features: I found the Delay Brew function perfect for waking up to the smell of coffee. The warming plate kept the carafe hot, and the used capsule storage bin, which holds up to 20 capsules, is a small but brilliant touch.
• ✅ Multiple Brew Styles: Having options for Espresso, Lungo, and Over Ice for capsules, plus Classic, Rich, and Over Ice for grounds, meant I could make the perfect drink for any mood. The “Over Ice” function brews a stronger coffee that doesn’t taste diluted.
• ✅ Thoughtful Design: The adjustable cup tray easily accommodated everything from a tiny espresso cup to my 8-inch travel mug, which is a detail many other machines get wrong.

Cons: What Could Be Improved

• ❌ Large Footprint: This is not a compact machine. Its all-in-one nature means it commands a significant amount of counter space, so you’ll need to measure before buying. It’s a coffee station, not just a coffee maker.
• ❌ Slight Learning Curve: With so many options for brew styles, sizes, and formats, it took me a few days to master all its functions. It’s intuitive, but you’ll want to read the manual to get the most out of it. Workaround: Start with one function (like grounds or pods) and gradually introduce the others.
• ❌ Higher Price Point: This is a premium-priced investment compared to simpler single-serve machines. It delivers incredible value for what it does, but it’s not a budget option.

Our Analysis

Espresso Quality & Bar Pressure

The standout feature of the Ninja CFN601 is its Barista Plus Technology. The 19-bar pressure pump is the real deal, providing the necessary force to extract oils and solids from the coffee, resulting in a rich, authentic crema. In my tests, the crema was thick, hazelnut-colored, and lasted for several minutes, a key indicator of a quality espresso shot and a major differentiator from pod-only machines that use low pressure.

Milk Frothing Performance

I was highly impressed with the built-in frother. It’s not automated, which gives you more control over the texture. The wand is powerful enough to create silky microfoam for latte art (with some practice) or thick, airy foam for a classic cappuccino. It works equally well for hot or cold frothing, and the fact that it folds away keeps the machine looking tidy.

Multi-Format Brewing Versatility

This is where the Ninja Espresso & Coffee Maker & Barista System, CFN601 truly shines. The ability to switch from Nespresso OriginalLine capsules to ground coffee (for single-serve cups or a full carafe) is seamless. The machine recognizes which insert you’re using and adjusts the available options accordingly. This means you can entertain a crowd with a full pot of drip coffee just as easily as you can make yourself a post-dinner espresso.

2. Ninja | Coffee Maker | Single Serve, PB051 Review – Best for K-Cup & Ground Coffee Versatility

The Ninja | Coffee Maker | Single Serve, PB051 is the perfect upgrade from a basic pod machine. It’s for the person who loves the convenience of K-Cups but misses the flavor and cost-savings of using their own fresh ground coffee. With multiple brew styles and an integrated frother, it delivers superior versatility in a compact, single-serve design.

Pros: What We Liked

• ✅ Pods & Grounds Freedom: The best of both worlds. I could pop in a K-Cup pod on a busy morning or use the permanent filter with my favorite ground coffee on the weekend. The flexibility is fantastic.
• ✅ Huge Range of Brew Styles & Sizes: This isn’t a one-trick pony. I could choose from Classic, Rich, Over Ice, or Specialty brews. The size selection is massive, covering everything from a 6 oz. cup to a 24 oz. travel mug.
• ✅ Effective Built-in Frother: The fold-away frother is a game-changer at this price point. It’s perfect for turning a regular coffee into a latte or cappuccino, and it works with hot or cold milk.
• ✅ Large Water Reservoir: The 56-oz removable reservoir was a huge plus. It meant I could brew coffee for days without constantly running to the sink for a refill, a major advantage over smaller machines.
• ✅ Excellent Flavor Extraction: Ninja’s Thermal Flavor Extraction DUO technology is impressive. It evenly saturates the grounds or pod, resulting in a rich, complex, and never-bitter cup of coffee. The “Rich” brew setting was noticeably bolder without being burnt.
• ✅ Smart, Compact Design: Despite all its features, it has a surprisingly small footprint. The clever storage drawer for the unused brew basket or pod adapter is a thoughtful touch that keeps countertops tidy.
• ✅ Travel Mug Friendly: It easily accommodates travel mugs up to 8 inches tall, making it perfect for taking your coffee on the go.

Cons: What Could Be Improved

• ❌ Strictly Single-Serve: This model is designed for one cup at a time. If you ever need to brew a full pot for guests, you’ll need a separate machine.
• ❌ Frother is Not Automated: You have to hold your cup under the frother wand while it works. It’s quick and easy, but it’s not a one-touch, fully automatic system like you’d find on super-automatic machines.
• ❌ Plastic Build: While solidly constructed, the exterior is mostly plastic. This is common for coffee makers in this category but lacks the premium feel of stainless steel models.

Our Analysis

Pod vs. Grounds Brewing Performance

I was keen to test the pod vs. grounds performance on the Ninja PB051. The K-Cup pod adapter works flawlessly, delivering a consistent cup quickly. However, the real star is the ground coffee performance. The included permanent filter and Ninja’s brewing technology extracted significantly more flavor from fresh grounds than a reusable K-Cup filter in a standard machine. This flexibility lets you enjoy convenience when you need it and superior flavor when you want it.

Specialty Concentrate & Frother Functionality

The “Specialty” brew setting is brilliant. It creates a super-rich, 4-oz. coffee concentrate that’s similar in strength to espresso. This is the perfect base for coffeehouse-style drinks. I’d brew a specialty concentrate, froth some cold milk with the built-in frother, and pour it over ice for a delicious iced latte in minutes. This combination is what truly sets it apart from standard pod brewers.

Design Footprint & Smart Storage

For a machine that does so much, the Ninja | Coffee Maker | Single Serve, PB051 is impressively compact. The designers made great use of space. The water reservoir can be positioned on the side or the back to fit different counter configurations. The small storage drawer underneath is a simple but genius feature that means you never have to hunt for the pod adapter or grounds basket.

3. Ninja Hot and Iced Coffee Maker, DualBrew Pro Specialty, CFP307 Review – Best All-in-One Brewer

The Ninja Hot and Iced Coffee Maker, DualBrew Pro Specialty, CFP307 is the ultimate kitchen workhorse. It’s designed for the household with diverse needs, replacing multiple appliances in one sophisticated package. If one person needs a quick K-Cup, another wants a full pot of drip coffee, and a third just needs hot water for tea, this is the machine you’ve been dreaming of.

Pros: What We Liked

• ✅ Ultimate Brewing Flexibility: This machine does it all. During testing, I brewed K-Cup pods, ground coffee in 9 different sizes (from a small cup to a full 12-cup carafe), and used the hot water dispenser. It’s the most versatile brewer on our list.
• ✅ Independent Hot Water System: This is a game-changing feature. A separate dispenser and water line for hot water means there’s zero coffee residue in your tea, oatmeal, or instant soup. The two temperature settings (Hot and Boil) are perfect for different uses.
• ✅ Four Distinct Brew Styles: The choice of Classic, Rich, Over Ice, and Specialty brew styles works for both pods and grounds, providing incredible customization for any coffee preference. The “Over Ice” brew is specifically designed not to taste watered down.
• ✅ Fast Brewing: Ninja claims it brews a coffee pod faster than leading competitors, and in my tests, it was impressively quick. From a cold start, I had a hot K-Cup coffee in just over a minute.
• ✅ Built-in, Fold-Away Frother: Like other Ninja models, the integrated frother adds the ability to create lattes and macchiatos, further cementing its status as an all-in-one coffee station.
• ✅ Robust Build Quality: This machine feels substantial and well-made. The sliding pod holder and other moving parts feel durable and built to last.

Cons: What Could Be Improved

• ❌ Large and Heavy: This is the largest and heaviest machine on our list. It requires dedicated counter space and is not easy to move around. You should definitely measure your space, especially under cabinets.
• ❌ More Complex to Operate: The sheer number of buttons and dials can be intimidating for new users. While powerful, it lacks the one-button simplicity of a basic Keurig. Workaround: The clear labeling helps, but expect a short period of familiarization.
• ❌ Premium Price Tag: As a high-end, multi-function machine that replaces three separate appliances, it carries a premium price. It’s a significant investment, but it delivers on its promises.

Our Analysis

DualBrew System Performance

The core of the Ninja CFP307 is its DualBrew system. A clever sliding brew head moves over either the pod holder or the grounds basket. I found the transitions to be seamless and the brew quality to be remarkably consistent, whether I was making a single 10-oz pod brew or a full 12-cup carafe. The machine intelligently adjusts the water volume and saturation time for each.

Independent Hot Water Dispenser

I can’t overstate how useful the independent hot water system is. On other machines, running a “water only” cycle often results in coffee-flavored water. The Ninja DualBrew Pro has a completely separate nozzle for hot water. I used it daily for my afternoon tea, and the water was always pure and clean. The “Boil” setting was hot enough for instant noodles, making this a true multi-purpose kitchen tool.

Iced Coffee & Specialty Brew Quality

The “Over Ice” function is expertly engineered. It automatically brews a stronger, smaller-volume coffee that, when poured over a full cup of ice, results in a perfectly balanced, non-diluted iced coffee. Similarly, the “Specialty” brew creates a rich 4 oz. concentrate that stands up beautifully to milk and ice, making it easy to create delicious lattes and other coffeehouse-style drinks at home.

4. Keurig K-Express Single Serve Coffee Maker Review – Best for Simplicity & Speed

The Keurig K-Express Single Serve Coffee Maker is the epitome of convenience. It’s designed for users who want a delicious, reliable cup of K-Cup coffee in minutes with the simple push of a button. If you value speed and simplicity over a long list of features, this is the perfect, no-fuss workhorse for your daily brew.

Pros: What We Liked

• ✅ Incredibly Simple to Use: This is the K-Express’s greatest strength. There’s a power button, three buttons for brew size (8, 10, or 12 oz.), and a “Strong” button. It’s completely foolproof.
• ✅ Fast & Fresh Brewed: From a cold start, it delivered a hot, fresh cup of coffee in just a few minutes. It’s perfect for those frantic mornings when you need caffeine, fast.
• ✅ Effective Strong Brew Option: The dedicated “Strong Brew” button makes a real difference. It slows down the brewing process to extract more flavor, resulting in a noticeably bolder cup. I used this feature constantly.
• ✅ Multiple-Cup Reservoir: The 42oz removable reservoir is a massive convenience. It lets you brew up to 4 cups before needing a refill, which is a huge upgrade over single-use reservoir models in the same price range.
• ✅ Compact and Sleek Design: It has a modern, slim profile that doesn’t eat up excessive counter space. At just over 5 inches wide, it fits easily into most kitchens.
• ✅ Travel Mug Friendly: By removing the drip tray, I could easily fit my 7.4” tall travel mug underneath, a crucial feature for commuters.

Cons: What Could Be Improved

• ❌ K-Cup Pods Only (by default): Out of the box, it lacks the versatility to brew ground coffee. Workaround: It is compatible with the “My K-Cup Universal Reusable Coffee Filter,” but this must be purchased separately.
• ❌ No Temperature or Iced Coffee Settings: Customization is limited to brew size and strength. There’s no way to adjust temperature or an “Over Ice” setting, so iced coffee can taste a bit diluted.
• ❌ Feels Less Substantial: The build is primarily lightweight plastic. While this is common and expected at its price point, it doesn’t feel as premium or durable as the Ninja models.

Our Analysis

Brew Speed and “Strong” Option

The core functions of the Keurig K-Express are where it excels. The brew process is quick and quiet. The “Strong Brew” button is the key feature that elevates it above more basic models. During testing, I found it added about 30 seconds to the brew time but resulted in a cup with more body and a richer flavor profile, which is perfect for dark roast lovers or for when you want your coffee to stand up to milk and sugar.

Reservoir & Drip Tray Design

Keurig nailed the convenience features here. The 42oz water reservoir is easy to remove, fill, and re-attach. The indicator light tells you when it’s time to add water. The removable drip tray not only makes room for taller travel mugs but also catches any stray drips, keeping your counter clean. These user-friendly design choices make a big difference in daily use.

Energy Efficiency

A small but appreciated feature is the auto-off function. The machine automatically powers down 5 minutes after the last brew. This not only helps save energy but also provides peace of mind, as you never have to wonder, “Did I turn the coffee pot off?” on your way to work.

5. Keurig K-Mini Mate Single Serve Coffee Maker Review – Best for Small Spaces

The standout feature of the Keurig K-Mini Mate Single Serve Coffee Maker is its incredibly small size. This coffee brewer is the perfect solution for anyone who needs a personal coffee maker but has virtually no counter space to spare. It’s the ideal choice for a dorm room, a small office cubicle, an RV, or a crowded kitchenette.

Pros: What We Liked

• ✅ Extremely Compact Footprint: At just 4 inches wide, this thing is tiny. I was able to fit it in places no other coffee maker on this list could go. It’s a true space-saver.
• ✅ Simple One-Cup Operation: The process is as simple as it gets: add the amount of fresh water you want to brew (6-12 oz.), pop in a K-Cup, and press the brew button. It’s perfect for occasional coffee drinkers.
• ✅ Travel Mug Friendly: Despite its small size, it accommodates travel mugs up to 7.25 inches tall once you remove the drip tray. This was a pleasant surprise and makes it great for on-the-go coffee.
• ✅ Sleek, Modern Look: The minimalist design and festive color options make it look less like a bulky appliance and more like a stylish accessory. It’s a great, budget-friendly gift.
• ✅ Affordable Entry Point: This is typically one of the most affordable ways to get into the Keurig ecosystem, making it a great starter coffee maker or a secondary machine for an office.

Cons: What Could Be Improved

• ❌ Single-Use Water Reservoir: You must add fresh water for every single cup you brew. This becomes tedious if you are a multi-cup-a-day drinker. It’s a major trade-off for its compact size.
• ❌ No “Strong” Brew Option: It lacks the ability to customize brew strength. The coffee it makes is good, but you can’t make it bolder like you can with the K-Express.
• ❌ Slower Brew Time: Compared to larger Keurig models, it generally takes longer to heat the water and brew a cup, sometimes over 2 minutes. This is not the brewer for someone in a hurry.
• ❌ Noisy Operation: For such a small machine, it can be surprisingly loud during the brewing cycle.

Our Analysis

Footprint and Portability

The primary benefit of the Keurig K-Mini Mate is its size. This is the machine you buy when every inch of counter space matters. Its slim, lightweight design makes it incredibly portable. I could easily see someone taking this with them for travel to use in a hotel room, or keeping it on their desk at work for a personal coffee station. Its use case is very specific, and it excels within it.

Single-Use Brewing Process

The “add water every time” process is the machine’s biggest pro and its biggest con. The pro is that you are always brewing with fresh water, which can lead to a better-tasting cup of coffee. The con is the inconvenience. If you want a second cup, you have to repeat the entire process of measuring and pouring water. This makes it best suited for people who drink one cup at a time, or for settings where convenience isn’t the top priority.

Design and Aesthetics

Keurig has positioned the K-Mini Mate not just as an appliance but as a decor piece. The minimalist design and variety of stylish color options allow it to blend into any environment. It’s an appliance that doesn’t look out of place on a bookshelf or a modern office desk, making it a popular and thoughtful gift.

This comparison highlights a clear divide. The Ninja models on our list dominate in features, versatility, and customization. They offer options for frothing milk, brewing multiple coffee formats (pods, grounds, carafes), and creating specialty drinks. They are true coffee stations designed for enthusiasts.

In contrast, the Keurig models excel at one thing: simple, fast, and convenient K-Cup brewing. They strip away the complexity to offer a straightforward, reliable experience. The trade-off is clear: choosing a Ninja like the Ninja Espresso & Coffee Maker & Barista System, CFN601 means a higher price and larger footprint for much greater capability. Choosing a Keurig like the K-Express offers a more budget-friendly and compact solution that is laser-focused on K-Cup convenience.

Buyer’s Guide: How to Choose the Right Single Serve Coffee System

Choosing the ideal single cup coffee machine comes down to matching its features to your personal coffee habits and kitchen space. Here are the key factors I focused on during my evaluation.

Key Features to Look For

• Brewing Versatility (Pods vs. Grounds): This is the most important decision. Do you want the ultimate convenience of pods (K-Cup or Nespresso), the better flavor and lower cost of fresh grounds, or a hybrid system like the Ninja PB051 that does both?
• Water Reservoir Capacity: A large, removable reservoir (>40oz) is a massive convenience that reduces daily refills. The Keurig K-Express‘s 42oz tank is a great baseline. Single-use reservoirs like on the K-Mini Mate should only be considered for very small spaces or occasional use.
• Brew Strength & Temperature Control: If you like a bolder cup, look for a “Strong Brew” option. This feature, present on the K-Express, makes a tangible difference in taste. Advanced users might seek temperature control, but a strong brew setting is the most common and effective customization.
• Milk Frother: If you enjoy lattes, cappuccinos, or macchiatos, a built-in frother is a non-negotiable feature. All three Ninja models on our list include one, instantly elevating your home coffee game and saving you money on cafe drinks.
• Footprint & Size: Measure your counter space before you buy! A compact model like the Keurig K-Mini Mate is essential for small kitchens, while a large all-in-one system like the Ninja DualBrew Pro needs a dedicated station.
• Brew Speed: If you’re always in a rush, look for models that advertise brew times under 3 minutes from a cold start. All the machines on our list are relatively quick, but the Keurigs are particularly known for their speed.
• Iced Coffee & Specialty Settings: Don’t just pour hot coffee over ice. Dedicated “Over Ice” or “Specialty” brew modes, found on all the Ninja models, create a stronger, more concentrated coffee that won’t taste watered down when chilled. This is a must-have for cold coffee lovers.

Matching a Coffee System to Your Needs

• For the Espresso & Latte Lover: You need a system with high bar pressure for authentic crema and a quality milk frother. The Ninja Espresso & Coffee Maker & Barista System, CFN601 is your best bet, with its 19-bar pressure and versatile frother.
• For the Busy Professional Who Craves Simplicity: You value speed and minimal fuss above all else. The Keurig K-Express Single Serve Coffee Maker provides a fast, reliable K-Cup brew every morning with zero guesswork.
• For the Budget-Conscious Experimenter: You want to use K-Cup pods for convenience but also fresh grounds for cost savings and better flavor. The Ninja | Coffee Maker | Single Serve, PB051 offers the best of both worlds in one machine.
• For the Small Apartment or Dorm Dweller: Space is your biggest concern, and every inch counts. The Keurig K-Mini Mate Single Serve Coffee Maker is the undisputed champion of compact design.
• For the Large Household with Diverse Tastes: You need a machine that can serve everyone’s needs. The Ninja Hot and Iced Coffee Maker, DualBrew Pro Specialty, CFP307 is the ultimate all-in-one solution, brewing single cups, full carafes, and even dispensing separate hot water for tea drinkers.

Frequently Asked Questions About Single Serve Coffee Systems

What is the best single serve coffee maker?

For all-around versatility, features, and performance in 2026, the Ninja Espresso & Coffee Maker & Barista System, CFN601 is our top pick. It’s the best single serve coffee system because it can handle Nespresso pods for real espresso, ground coffee for single cups or a full carafe, and includes a high-quality milk frother. However, the “best” machine for you ultimately depends on your specific needs for space, budget, and coffee type.

Can I use ground coffee in a single serve brewer?

Yes, many modern single serve brewers are designed for this. Models like the Ninja PB051 and Ninja CFP307 come with a permanent filter basket specifically for brewing ground coffee. For pod-only machines like the Keurig K-Express, you can purchase a “My K-Cup” universal reusable coffee filter separately to use your own grounds.

Which single serve coffee maker is best for small spaces?

The Keurig K-Mini Mate is the best option for small spaces. At only 4 inches wide, its ultra-compact design allows it to fit in tight spots like dorm rooms, small office desks, or crowded kitchenettes where a traditional coffee maker would be too large.

What’s the difference between Keurig and Nespresso single serve machines?

The main difference is the type of coffee they brew. Keurig machines use K-Cups, which are a form of drip brewing, to make American-style coffee. Nespresso machines use smaller capsules and high pressure to brew authentic, crema-topped espresso. Our top pick, the Ninja CFN601, is unique because it is Nespresso-compatible and also brews drip-style coffee.

How often should I descale my single serve coffee maker?

You should descale your machine every 3-6 months, or whenever the indicator light comes on. If you live in an area with hard water, you may need to do it more frequently. Descaling removes mineral buildup from the heating element, which improves performance and extends the life of your coffee maker.

Which single serve coffee maker makes the hottest coffee?

In our testing, the Ninja models consistently produced very hot coffee, with brew temperatures right around 200°F. All of our top picks brew coffee well within the optimal brewing temperature range of 195-205°F, ensuring proper extraction and a hot cup. If you find your coffee isn’t hot enough, pre-warming your mug with hot water can make a big difference.

Our Final Verdict on the Best Single Serve Coffee System in 2026

After extensive testing for 2026, one thing is clear: the modern single serve coffee system is about balancing incredible versatility with everyday convenience. The market has evolved far beyond simple pod brewers, now offering excellent choices for every need, from simple, fast machines to complex all-in-one barista stations that can truly replace your daily coffee shop run.

Perfect for you if…
* You want the ability to brew espresso, drip coffee, and full carafes.
* You love lattes and cappuccinos and need a quality milk frother.
* You enjoy the quality of Nespresso pods but also want to use grounds.
* You see your coffee maker as a long-term investment in your kitchen.

Not ideal for…
* You have very limited counter space.
* You only drink K-Cup coffee and want the simplest possible operation.

While all the machines on this list are excellent for their specific use cases, one stands head and shoulders above the rest for its sheer capability and quality.

Ultimately, choosing the right single serve coffee machine will transform your morning routine. We are confident that our top overall pick, the Ninja Espresso & Coffee Maker & Barista System, CFN601, delivers the best combination of features, quality, and versatility available today.
