Keurig K50 VS K55 Review & Comparison

The Keurig K50 and the Keurig K55 are very similar – they look aesthetically identical, but they are two different, single serve coffee brewers. The K55 is also known as the K-Classic coffee maker. It’s the newer one of the two models, and it has a price tag to prove so… But is it worth the price difference? Has Keurig duplicated the K50 (which initially did not have a famous title) and perfected it, or are it’s “new” features truly different? Overall, the Coffee Dorks team has tested, reviewed and rated almost every Keurig machine out there. This triggered us not only to drink many cups of coffee, but also to compare these two models and write up this article. We will give you the chance to compare the Olsen twins of the coffee machine world with no problem.

Keurig K50 VS Keurig K55 Performance

Keurig K50 VS Keurig K55 Performance

The first thing we should state is that the brew speed in our table above is for the most important one, first cup of coffee in the morning, from the second you turn it on to the point where you have a full cup of coffee. Then, your second or third cup once the machine has warmed up will bring you closer to the 1-minute mark.

The K55 was nearly on 1 minute, while the K50 was near to 1 or 1.5 minutes – which is not a big difference.

Both models are designed to be fast, simple and effective. There’s no LCD screen on both of them, just buttons, and the entire process for making coffee is the same. The brew temperature for both is 89°C.

However, when it comes to filters, we can certainly see a difference. The older model, K50, has simple mesh reusable filters – which are not high quality and you will most likely need to replace them sooner rather than later.

The K55 has activated charcoal filters, which are very helpful and create a more supreme and smooth coffee. But also, whether these charcoal filters are worth the extra $$ you pay, that’s totally up to you.

Both machines switch off automatically and have no timer at all.

Keurig K50 VS Keurig K55 Taste

Keurig K55 VS Keurig K50 Taste

For the taste, we had to do some blind testing. The results were kind of odd. Both tasted almost the same.. which is because both machines are K-Cup compatible, and the flavor was basically the same.

You can use the K-Cups and even the cheap non-official K-Cups in both machines, but neither can use K-Carafe or K-Cups 2.0

The taste isn’t bad in either– with a massive range of pods from Keurig, you’re inevitably going to find something you like. Some Coffee Dorks thought that the K55 brewed a bit of a stronger coffee, but personally, I couldn’t notice the difference.

Keurig K50 VS Keurig K55 Cleaning & Maintenance

The official Keurig user guide for the K55 is called the K-Classic User Guide, which is both for K55 and K50, so it doesn’t help clarify the differences. Yeah, thanks a lot, Keurig.

Cleaning and maintaining these machines is pretty much the same. Remove the drip tray and reservoir regularly to clean them, then run through their descaling programs (basically, run chemicals through it a few times, then run through the water until it is spotless). The K55 has auto-descaling, whereas the K50 doesn’t. It is not a big deal if you have the K50, it’s mostly the same process as brewing a coffee but with descaling solution instead.

There is also guidance in the User Guide for cleaning the pod holder, exit needle, entrance needle and funnel.

The cleaning is a straightforward process, and because these coffee machines are almost identical, if you need to replace a particular piece inside the machine, finding that part is simple (try eBay). However, the K50 is more prone to breaking down than the K55, if you compare the reviews from customers.

Keurig K50 VS Keurig K55 Aesthetics

Even though it’s at the bottom of our comparison list, it’s still essential.

The K50 is a little heavier, but the dimensions of both machines are pretty much the same. They are medium-sized brewers, so they’ll fit on your worktop quite nicely, and they’re mostly made of plastic. They’re not bulky – so if we could look for a word to describe their looks, it would be “standard.”

Both machines come in black or “rhubarb” red. The red one looks cheaper – the matte black looks a bit classier, but on closer notice, it’s quite obvious that it’s not made of high-quality materials.

The buttons on both are lovely – so, instead of using a budget LCD screen, they’ve entirely ditched the screen. The buttons light up, so they’re easy to control in the dark if you’ve snuck downstairs for a quick cup of coffee, and they do not feel cheap to press.

When it comes to taste and performance (the two most essential things in an actual coffee machine), there is almost no difference at all. In fact, we did a blind test and only several Coffee Caller could pick out which one they liked better. The noticeable difference between these two machines is their maintenance and aesthetics.

The K55 surely looks better and lasts longer.

It seems that Keurig have taken some examples from Apple’s book. Their newer model is nearly the same, just with a price increase that’s kind of unexplainable when you take a look at the real differences.

Coffee Caller Prefer:

Overall, we all agreed that if we had to buy one of these coffee brewers for our personal use, it would probably be the newer one, K55. What made us choose this one is the fact that the K55 just feels sturdier. Plus, it is going to last longer. Although the changes are minimal, Keurig has undoubtedly put more effort into quality and efficiency checks for the K55.

Keurig K55

If you’re like us and you’re after quality and a handy machine that can keep up with your standards every day, go for the K55. If the budget is worrying you, then just go for the K50. It’s really not that different and you’ll be getting almost all of the same features the K55 has either way.
