Keurig K50 Brewer Review
Keurig K55 Brewer Review
We can’t compare products without talking about performance.
Does it then imply these modifications make the K55 a better performer vs the K50?
Let’s try and answer that by looking at the main differences below:
- The K55 has better functionality which makes it possible to prepare a cup of coffee in just under a minute. The same can’t be said about the K50 as it takes an extra 30 seconds to achieve the same result.
- The K55 is more durable and reliable than its K50 counterpart.
- The K55 comes with different cup sizes so you can select the size of cup you want. The K50 comes with a standard size cup.
- The K55 comes with a descaling feature that removes calcium deposits that build up over time inside the coffee machine. This feature isn’t present in the K50.
Let’s be clear that the K55 isn’t necessarily better than the K50 in all aspects. The K50 comes with its own benefits which include:
- It’s reasonably sized and fits just about any kitchen, even small ones.
- The K50 coffee maker is compatible with all Keurig K Cup pods and you can use pods from other brands like Walmart & still get the same result.
- You can use the special filter provided or you can purchase your own grind.
Taste has to be one of the most important aspects you consider before deciding to purchase a coffee maker. You’ll want to know if the use of either machine will alter the final taste of your coffee.
Generally, you’re guaranteed the best taste from the first six ounces of coffee you make from both the K55 and K50 after which the strength starts to decrease.
To some extent the K55 brews stronger coffee but the difference is minimal. However, it has been reported after some time of using the K50, the coffee suddenly develops an unpleasant taste, something reminiscent of burnt rubber or plastic. This chemical taste is, unfortunately, accompanied by an odor too.
The K50 model also doesn’t work well with a reusable filter and it makes a mess during brewing. You waste water and filters which isn’t environmentally friendly.
How does the K55 model fare with regards to the taste of coffee? It has two water filters which ultimately make the coffee taste better than when the K50 is used. You can use filtered or bottled water if you want an even better tasting cup with the K55 coffee machine.
- If you use your own coffee grind.
- The initial flow from the k cup contains a higher concentration but it drops over the entire cycle time and becomes watery.
How Do You Keep Them Clean?
Now that we’ve noted some differences in terms of both their performance let’s look at cleaning the machines.
To get the best performance from your coffee maker you need to clean it. Both the K50 and K55 have the same precautions you need to take:
- If you only use the machine to make coffee cleaning it once a month will suffice.
- If you use it for tea, run clear water through the machine each time before brewing your next cup.
- If you use it for hot chocolate clean the machine thoroughly and never let the machine set without cleaning.
After the above considerations it’s safe to conclude that even though they’re both similar in design, the K55 offers more capabilities for better performance.
