Keurig K-CLassic Review | A Detailed Go Through

K-classic combines the well-known efficiency of k-cup technology with a convenient design. Although it lacks many features, but still it comes with all the basic and necessary features that an average coffee drinker needs.

Let’s dive into a review of Keurig k-classic.

1) Design and the quality of Keurig K classic

Keurig k-classic doesn’t look particularly amazing but is perfect for traditional kitchens. The overall dimension of the machine reveals that it has a footprint of 1 square foot which is quite big for a single-serve coffee maker.

The machine is quite tall (13.4 inches),10.1 inches wide, and 13.2 inches deep. When the pod chamber is open, the height rises to about 17.6 inches which is pretty high to fit under some kitchen cabinets. 

Also, it doesn’t come in any fun color. Only 2 colors are available: Black and rhubarb, so you have limited options to choose from that suit best your kitchen aesthetic.

The machine is entirely made of BPA-free plastic, which somehow gives it cheaper look. But you don’t need to worry about K-Classic’s long-term durability.

I can’t find any single complaint about the degrading of the machine over time. The good thing is it comes with a 1-year warranty so, in case of any malfunction or breakage, you can contact Keurig for replacement or repairs.

The transparent water reservoir is removable and the good thing is it doesn’t start brewing unless there is enough water so that’s a positive approach toward safety concerns.

Overall, the design of Keurig K-Classic is just fine, I am not quite impressed with the design as it is way bulkier for a single-serve coffee machine.

2) Performance of Keurig Classic

One thing that I really appreciate about k-classic is its performance.

Simplicity and convenience are two main crucial advantages of k-classic.

Brewing time is something that I never expected. While testing I found that it hardly takes 60 seconds from start to finish to brew a cup of coffee.

Another drawback is that k-classic lack many programmable features like temperature control functionality, strength control, a strong brew option, and hot water on demand. Stong brew option can be compensated by investing in k-cup pods that match your desired flavor.

The temperature of the coffee drink from this machine lies in the range of 170 to 175 degrees which is satisfactory for a pod-based machine.

On the positive side, the machine is compatible with my k-cup reusable filter, so you can use your own ground coffee.

Overall, in this price range, the performance of the machine is quite satisfactory.

3) Cleaning and maintenance

Keurigs are popular among coffee lovers because they are easy to clean. So is the case with k-classic. The K-Cup contents never come in contact with the internal components of the Keurig, and that’s why there is no mess as in traditional brewing.

Cleaning the k-classic is like child’s play. Just remove the used K cup and clean the K cup holder every time after brewing and you are good for the next brew.

It is recommended to clean the exterior, the drip tray, and the water reservoir at least once a week.

The descaling light will blink when the machine needs to be descaling, and it is recommended to do so immediately. Descaling is also a very simple process you simply need to fill the water reservoir with descaling solution and water and run brewing cycles until the reservoir is empty.

Overall the Keurig k-classic requires little maintenance and is much easier to clean.

4) Taste and quality of the drink

The taste mainly depends on the type of K cup pod you use while brewing coffee with K classic.

Keurig k-classic lacks programmable features like temperature functionality control and strength control, so ultimately this limits flavor variety in your cup of coffee.

This machine is compatible with the My k-cup reusable filter so you have the freedom of using your favorite coffee grounds. It is recommended while measuring ground coffee, not to pack coffee too tightly as it may lead to an overflow in the coffee maker.

The machine offers three brew sizes 6 oz, 8 oz, and 10 oz. In my experience, only a 6 oz brew size produces the best-tasting cup of coffee. 8 oz and 10 oz brew sizes result in a bitter and watery cup of coffee.

This machine is certainly not perfect for strong coffee lovers as it lacks the feature of a 4 oz brew size and strong brew button.

Overall, the taste is quite satisfactory and you will love it if you have been using k cup coffee makers for a while.

5) Ease of use

From filling the removable water tank to cleaning and maintenance, k-classic is all about simplicity. Instead of a complex touchscreen panel, a button control panel is present which is very simple to use. All buttons are labeled and get illuminated while functioning.

The brewing process is like cherry pie. In about two minutes, you will have a coffee cup in your hand. All you need to fill the water reservoir, insert your preferred k-cup pod, and press your desired brew cup size.

A few useful indicators are also present on the control panel to help you use the Keurig K-classic coffee maker optimally:

  • Auto-off feature: When activated, the auto-off feature will turn off the machine after 2 hours in case of no activity to save energy.
  • Descaling: This light turns on when the machine requires descaling.
  • Add water: This light turns on when there isn’t enough water in the reservoir.

6) Value for money and Customer reviews

Although it lacks many programmable features, yet the simplicity and convenience it offers are good enough to justify the price tag. Yeah! you can find better coffee makers for under 150 dollars than it. Despite this, Keurig is a brand that is trusted and reliable and costs more as well.

Keurig K-Classic is the best-selling Keurig model and more than 90 percent of users are completely satisfied with this machine.

Overall, k-classic has almost 90k reviews on Amazon, with an average rating of 4.7 out of 5. This shows the popularity of this single-serve coffee maker. This is a highly reliable single-serve coffee machine that is efficient, simple to operate, and the most user-friendly model available in the market now.

There are few negative feedbacks regarding the plastic taste of coffee and limited customization options but the majority are completely satisfied with the machine’s performance.
