Are you the ideal Keurig K-Classic buyer?

Best Coffee Makers - Keurig coffee machine reviews

Any good Keurig K-Classic coffee maker review will detail the various aspects of this model that make it a perfect fit for certain kinds of users.

So let’s examine whether the Keurig Classic is the right match for you – or if another coffee machine model would work better.

If you’re a coffee aficionado who likes to try out variations and new ideas in your morning brew, you’ll find the Keurig K-Classic coffee maker somewhat cramps your style.

You’d do better with a coffee maker that leaves a user with more control.

It’s also not a great choice for users who make complicated beverages or use coffee grounds to whip up their drink. That requires a coffee machine with greater flexibility and versatility.

Some coffee drinkers might prefer to vary the strength and hotness of their coffee, and find the Keurig K-Classic coffee maker’s limited programmability stifling.

And last but not least, while the Keurig K-Classic coffee maker is indeed stylish and elegant, it lacks the appearance of a top-shelf device because the plastic finish can seem somewhat cheap.

But if none of these reasons matters to you, then maybe you’re the ideal Keurig K-Classic owner!

Appearance and Design

Keurig K Classic coffee maker design

If you browse images of the Keurig K-Classic coffee maker online, you’ll be blown away by how cool it looks.

That’s also exactly how it looks for real!

It is a brilliantly designed coffee machine with a simple layout, 4-button operation, compact and not too heavy.

This device is one where form follows function.

It offers basic coffee making functionality and is easy to operate. A control panel on the front has 5 buttons with indicators to tell you when it’s time to add more water or descale the equipment.

  • Three of the buttons are to select the brew size.
  • One is a Power button to switch the coffee maker on and off.
  • The last one is to activate the ‘Auto Off’ feature.

The large water reservoir is transparent, can hold 48 oz, and is neatly positioned by the side.

If you take away the drip tray, a taller mug can fit under the water spout. The Keurig K-Classic coffee maker comes in a choice of white or black.

The only minor grouse a discerning consumer might find in the Keurig K-Classic coffee maker is how the plastic finish isn’t as classy as the polished metal models.

You have a choice of 3 different cup sizes6, 8 or 10 ounces.

By pressing a button to indicate your choice, the Keurig K-Classic coffee maker will suitably adjust all other settings.

The device is a lightweight. Weighing little under 4 kilograms (or 9 pounds), it can be easily carried or moved around.

It is however somewhat tall, measuring 13.5 inches in height (add 4 inches to it when the lid of the coffee pod chamber is open).

 Powerful Performance

Coffee drinker coffee maker - Keurig K-Classic coffee maker review

The Keurig K-Classic coffee maker brews great coffee quickly and effortlessly. Any performance review focuses on brewing speed.

And this machine is blindingly fast.

All it takes is 60 seconds or less to have a steaming mug of tasty coffee ready. That’s a perfect accessory for people in a hurry!

While some purists might say the lack of control over temperature or strength is a drawback, most users are delighted with the rich coffee brewed within minutes.

It takes roughly a minute to make a 6 oz mug of coffee.

That’s impressively fast, especially when you’re in a hurry and looking forward to grabbing your drink and getting back to work.

It’s true that there’s less control over flavor and strength with personal preference mainly achieved through a selection of K-cups. Still there’s no question that the coffee is tasty and rich.

Water temperature reaches 180F which is perfect for brewing. However there’s no way to manually regulate this heat.

The coffee maker is quiet and apart from a soft whirring sound while at work, it is practically noiseless.

Keurig K-Classic Review

Maintenance is Quick & Easy

The Keurig K-Classic coffee maker is amazingly easy to clean after use.

The drip tray and K-cup pod holder are dishwasher safe. Running a damp cloth or sponge over the machine is often enough to keep it clean.

Over time and with regular use, your coffee maker will accumulate deposits of calcium and other minerals. This interferes with function.

Descaling is recommended once in every 3 to 6 months.

Apart from a few anecdotal reports of users facing trouble with their Keurig K-Classic, there have been no systemic concerns. Keurig is a reputed manufacturer and stands solidly behind the company’s products.

If there is a genuine malfunction or production fault, Keurig may replace the machine for free.

Taste Testing

If you’re a coffee gourmet, don’t expect anything extraordinary when it comes to taste.

With the Keurig K-Classic, you’ll enjoy a decent cup of rich coffee, but won’t be able to control many aspects like temperature or strength.

Of course you can add a little more water or brew with a larger mug to get a weaker brew.

Another problem is that you’re limited to using K-pods and cannot use coffee grounds of your choice or preference.

Keurig K-Classic Review

Safety and Health

All components are made from safe BPA-free plastic and aluminium. The device has met safety standards to be certified by the FDA.

Some users have voiced concerns about boiling water coming into contact with plastic components.

But the manufacturer has clarified that water temperature is always well below the melting point of coffee pod materials and plastic will not leach into any drink.

The risk lies only in using any replacement parts from other manufacturers who may not follow stringent BPA-free guidelines.

Another possible downside that’s shared by all single serve coffee makers is that they are allegedly prone to growing bacteria and mold.

Finally, since the Keurig K-Classic Coffee Maker runs on K-cups, it may be worth becoming informed of the environmental concerns  associated with the use of coffee pods over the years.

Price & Value for Money

The Keurig K-Classic coffee maker occupies a sweet spot of being excellent value for its affordable price.

Keurig K Classic coffee maker value


With a larger budget, there are better choices like the Keurig Duo coffee maker and Keurig Duo Plus, or even the Hamilton Beach FlexBrew model.

But for the price you’d be hard pressed to find a more versatile, functional and effective coffee maker than the Keurig K-Classic that:

  • brews delicious coffee,
  • looks great on any kitchen counter, and
  • packs a powerful punch

For these reasons the Keurig K-Classic coffee maker has little serious competition for the title of best single cup coffee maker.

One thing to factor into price is the ongoing cost of coffee pods that are needed to brew your coffee.

Depending upon your choice of pods, this can add up to a sizable expense and coffee pods are often costlier than ground coffee.

A Word About K-Cups

Keurig K-cups - Keurig K-Classic coffee maker review

Yes, Keurig K-Cups come in a wide range of flavors from hot chocolate to rich coffee blends. By trying different pods you can experiment with various flavors.

But this quickly gets quite expensive, not to mention the harmful environmental impact of discarded cups.

That’s why you should consider getting a K-cup reusable filter.

In case you’re used to a type of roast, the Keurig K-Classic coffee maker includes the option to use an empty Keurig K-Cup adaptor for ground coffee.

Better tasting coffee, and it’s much more customizable. Plus you’ll help keep the world clean!

But be careful.

Adding too much will make the machine overflow. Of course if you’d like to avoid K-cups entirely, a pod coffee machine offers a valid alternative.

Keurig K-Classic Coffee Machine FAQs


1. Can the Keurig K-Classic coffee maker make espresso?

No, the brewing process with a Keurig K-Classic doesn’t involve pressure which is necessary for espresso. Single-serve coffee makers that can prepare espresso exist. The automatic Nespresso machines are a great choice.

2. Can all coffee pods be used with the Keurig K-Classic?

No. Nespresso coffee pods are not compatible with the Keurig K55 K-Classic model. Neither are K-carafe or K-Mug coffee pods which go only with the Keurig K-Plus coffee maker series.

3. Are the Keurig K55 and Keurig K50 identical?

No, they are distinct models but share a few features in common. While the K50 does offer the option to prepare a Strong Brew, it takes a little longer to brew your cuppa.

The K50 also does not have an Add Water indicator to remind you to refill the reservoir, or a Maintenance Reminder when a descaling is due.

The model has now been discontinued by the manufacturer, so there’s little risk of accidentally ordering one instead of the Keurig K-Classic coffee maker you want.

4. Is this the best Keurig coffee maker model?

The best Keurig coffee maker is the one that matches your needs.

Some like the K-Mini Plus can make only a single cup of coffee before the reservoir must be topped up. The K-Elite model has bells and whistles of a premium coffee maker.

If you want a no-fuss, low maintenance, quick and convenient single serve coffee maker, the Keurig K-Classic is a great choice.
