With a 48-ounce water reservoir, you can brew 6 cups of coffee or more with the Keurig K55 K-classic coffee maker. And you do not need to refill the tank.

The machine brews a number of K-Cup pod sizes, ranging from 6-10 ounces. If you want to have a cup of the strongest brew, the 6-ounce brew size does the job. 

It has a one minute brew time, which makes it the perfect machine to give you a quick cup of caffeine when you are in a rush. 

Design and Construction

Keurig K55 K-classic single serve coffee maker sports a modern and unique design. You do not commonly see this type of build in other coffeemakers on the market. 

Unlike the Breville BDC650BSS Grind Control Coffee Maker, which is made out of stainless steel and plastic, the Keurig k55 single serve K cup coffee maker has plastic construction. It does not feel flimsy at all, however. 

Keurig has successfully created a programmable coffee machine that wins on both design and construction. It looks good on any countertop and is built durable enough to work for a considerable amount of time. 


The Keurig K55 classic brewing system is an average-sized coffee maker, making it ideal for small to medium-sized offices or apartments. The Keurig K55 K-classic coffee maker is 13.3 inches high, 10.1 inches wide, and 13.2 inches deep. Finding a spot for it on a countertop or any surface is easy. 

To help you better picture its actual size, the Keurig K-Select Coffee Maker is a few inches smaller than the Keurig K55 K-classic coffee maker in terms of overall dimension. 

It only weighs 10.6 pounds. You can move the appliance from one countertop to the next without the need for assistance. It also has the same weight as the Keurig K-Elite Single-Serve Coffee Maker but is a pound lighter than Keurig K-Select Coffee Maker.


As mentioned earlier, the Keurig K55 Elite coffee brewer and the Classic version are primarily made of plastic that is durable and strong. You do not have to worry about the plastic parts coming off from the Keurig K55 single serve K cup coffee maker. 

It is recommended that you take extra care in handling to make sure it works for longer. As much as possible, avoid moving it frequently. This coffee machine has a one-year warranty to back you up as well. 

Safety Features

Just like the Keurig Elite Brewing System K55 coffee maker, the K-Classic also automatically turns off on its own when left idle for two hours. This not only helps lessen energy consumption but also ensures you come home with the appliance still intact. 

If you are in a rush, you might forget to turn off the machine. Without the auto-shut-off feature, the plastic parts could melt. So not only is the K55 K-Classic an economical choice, but also a safe one. You have one thing less to worry about. 

It is a fully programmable coffee maker with an indicator light for convenience. When the reservoir needs refilling, the light will turn on. 

Accessories Included

The machine comes with Keurig K55 coffee pods of 4-count variety packs. Keurig provides you with quality and hot cocoa collection along with the package to give you the full experience. You can get these pods from their official website and from other online platforms. 

The machine has a large 48-ounce water reservoir, which saves you time from refilling water. If you normally consume a single serve of coffee two times in one day, the reservoir will last for a few days.

All coffee pod brands are compatible with this coffee machine, giving you the freedom to choose your preferred K-cup pods based on taste and budget.

Brew Time

If you are in a rush, this Keurig k55 Classic brewing system produces a hot cup of coffee in under one minute. You always have your caffeine fix in the shortest time possible. 

Unlike other coffee machines, such as the Cuisinart DCC-3400, you are unable to program the machine to brew coffee ahead of time.

Brew Quality

The K55 K-Classic follows an easy brewing process, giving you a rich and flavorful cup of Joe under one minute. You can also use this machine to brew ground coffee as well.

You can brew coffee in different sizes to fit your preferred taste and needs. As seen on online Keurig coffee maker reviews, users love the fact they get to choose whether to brew a 6-ounce, 8-ounce, or a 10-ounce cup. 

If you are looking for a strong cup of coffee, choose the 6-ounce cup option.

Use the same machine to brew iced beverage with just a touch of a button. Just wait for one minute and voila! Your iced coffee is ready.

Ease of Use

In many Keurig coffee maker reviews, the machine’s simple and straightforward operation takes front and center. Who needs a complicated set of buttons when you just need a good dose of good coffee quickly anyway? 

It is super easy to use. Moreover, there is no need to purchase additional filters as it is a simple brew-and-go machine. In addition, you do not have to worry about the appropriate water level per brew.

To brew coffee, pour water into the machine’s water reservoir, pop in a K-Cup pod, and then wait for a minute. With a low-barrier to enjoying a cup of Joe, this appliance is ideal for beginners.

If you want to make sure you are doing things properly, you can refer to the Keurig coffee maker K55 manual. It is easy to understand and it only takes a few minutes to figure out how the machine works.


In a Keurig K55 review, we found out that the clean-up does not demand a lot of time mainly due to its removable parts. The coffee maker’s drip tray and water reservoir are removable, so you can easily clean it up once a week. 

You will need to descale your coffee maker once every 3-6 months, depending on how often you use it. There is an indicator light that will tell you it is time to descale it. You do not have to manually set a time and date for descaling. 

You may use Keurig Descaling Solution (1) or a white vinegar liquid solution to descale the machine, it depends on which you are more comfortable with. The descaling process eliminates calcium deposits that build up inside the machine over time and compromise coffee quality in the long run.

Brand & Customer Service

Keurig is one of the leading brands in coffee makers in the market, but they do not specialize in one product line alone. They consider themselves “A new challenger in the beverage industry” and rival companies see them as a notable competition.

They focus on creating product lines for tea, water, juice, and mixers with design and innovation at the company’s core. As a result, their customer service is top-notch. Keurig only works with qualified professionals as their front liners.

You can contact them on their official website (2). They will respond to your inquiry within 48 hours. However, their team always replies within the 24-hour mark. 

Value for Money 

Is the Keurig K55 coffee maker price worth it? Definitely!

It is an easy-to-use machine that gets the job done quickly. Do you need a cup of coffee? It only takes a minute for the machine to brew, giving you quality coffee one cup at a time. 

It has a large water reservoir at 48 ounces. You do not need to refill unless you are serving a huge number of people. 

This unit saves you money on electricity bills because it automatically turns off when left unused for two hours. It has clear indicator lights when the reservoir is empty and when it is time for descaling. 


In this Keurig K55 review, I am going to list down some of the appliance’s share of downsides. 

  • Noisy operation
  • Lacks the ability to adjust the brew strength
  • Some say, it easily clogs
  • Frequent use may mean, frequent descaling than recommended

Who Should Buy this Coffee Maker? 

The Keurig K55 is for anyone who is looking for a simple coffee machine that produces a quality cup of coffee in one minute. If you are a beginner, an easy-to-understand Keurig owners manual K55 will get you started in just a few minutes.

This coffee maker is perfect for anyone who wants a hassle-free clean-up process. The parts are easy to remove and maintain, so you can get it up and running like a brand new machine right away.

If you are always on the go, the Keurig K55 K-classic coffee maker will suit you perfectly. You will have a partner in the morning and a friend for a very long time.

Final Verdict

The Keurig K55 coffee maker scores 4.2 out of 5 stars, mainly because it is an easy-to-use machine that brews quality coffee in just a minute. 

The coffee machine can hold tall travel coffee mugs (7.1 inches tall)too, making it perfect for anyone who wants to enjoy the beverage at any time and place. All you have to do is to remove the drip tray and you can have rich coffee on-the-go.

While it does make loud sounds during the brewing process, it is not a major concern and does not affect the drink’s quality. Do you need a quick cup of coffee? K55 K-Classic Single Serve Coffee Maker is right on the money!
