Key Features: K-Select vs K-Classic

The K-Select and the K-Classic come with a bunch of interesting features that make brewing coffee a very nice experience. We’ll talk about their water tanks, brew sizes, and more.

Brew Sizes

Brew sizes of the K-Select:

  • 6oz
  • 8oz
  • 10oz
  • 12oz

Brew sizes of the K-Classic:

  • 6oz
  • 10oz

The K-Select has an additional brew size compared to the K-Classic.

Having several brew sizes to choose from gives you more flexibility so you can experiment more with flavors and sizes. That’s why the K-Select is the winner here.

Winner: Keurig K-Select

Water Reservoir

When comparing the Keurig K-Select vs K-Classic we found a couple of key differences that should be mentioned.

The first one is that the K-Select comes with a large removable 52oz water reservoir, while the K-Classic has a 48oz reservoir.

This means that the K-Select can brew more cups of coffee before having to refill the water reservoir again.

Note that the tanks on both machines are compatible with Keurig’ charcoal water filters, which is great if your house water is not so good.

A major disadvantage of both machines is that according to many reviews, their water reservoirs are pretty uncomfortable to grab. In fact, many people like to just not remove the reservoir and fill it with a water jar.

A nice addition is that both water reservoirs come with a “Max” line so you know immediately when they’ve reached their full capacity.

Since the K-Select has a bigger water reservoir, it is the better option.

Winner: Keurig K-Select

Ease of Use

Now, in terms of ease of use, they pretty much work exactly the same.

Fill the water reservoir, turn on the machine, wait until it has finished warming up, add a K-Cup, and select a brew size. Easy isn’t it?

In terms of interface, they have almost exactly the same layout, the K-Select has just 6 buttons (4 for selecting brew sizes, a power button, and a button for activating or deactivating the strong mode).

On the other hand, the K-Classic has just 5 buttons (3 for selecting brew sizes, a power button, and a button for activating or deactivating the Auto-Off feature).

You can notice that the K-Select doesn’t have a button for activating or deactivating the Auto-Off feature (we are going to talk about this feature later), but in fact, it is very easy to do.

You just have to press the strong and the 10oz. Large Mug buttons for 3 seconds (while the machine is turned off but connected to a power source) until the green Auto Off light will turn off.

After that, you can power the machine on and it will have the Auto Off feature deactivated.

To turn this feature on again you just have to repeat this process.

Both coffee makers come with several indicator lights that add even more convenience to their daily use.

The K-Classic comes with the following lights:

  • Add water
  • Descale
  • Heating
  • Auto Off
  • Power

The K-Select comes with the following lights:

  • Add water
  • Descale
  • Auto Off

Here’s a quick video on how to use the Keurig K-Select (the machine is already warmed up). This is the exact same process you should follow with the Keurig K-Classic.

If you want more information about how to use these coffee makers check the user their user guides.

So, since both machines are really easy to use, and both come with a lot of convenient features we consider them tied in this aspect.

Brew Quality and Performance

Let’s talk about the differences in brew quality and performance between the Keurig K-Select vs K-Classic.


Both take between 3 to 4 minutes to heat up for the first time. In addition, both take about the same amount of time to brew, taking about 40 seconds to brew an 8-ounce cup of coffee.

If you activate the strong mode on the K-Select, it will take about 10 seconds longer.


The coffee brewed by these machines reaches a temperature of 160°F – 170°F. No major difference between them in terms of temperature.

This temperature should be enough for most people since it is pretty hot.


These coffee machines use K-Cups, and it is necessary to make something clear about K-Cups.

Their flavor is not for everyone. Before saying that the coffee made by these machines is good or bad you should decide if you like K-Cups or not.

Now, the coffee from both machines tastes practically the same, however, if you want the coffee to be better take into account the following tips.

For a more intense flavor, you have to use the 6oz size, and if you decide to choose the K-Select, you will have the strong mode available which increases the intensity of the coffee even more (it takes a little longer to brew).

Now that you know this, you should know that the larger the size of the coffee, the more watery it will be.

Which Coffee Maker Brews the Best Coffee?

So, as these machines prepare coffee at almost the same time, produce the same temperature and the taste is very similar, we can conclude that neither machine makes better or worse coffee, it all depends on how the machine is used.

However, despite all this, the K-Select has a great advantage. This coffee maker allows you to brew even more intense coffee if the strong mode is enabled. For this reason, it is a little better than the K-Classic.

Capsule Compatibility

Both machines are compatible with Keurig and non-Keurig K-Cups as well as reusable K-Cup compatible coffee filters.

Cleaning and Maintenance

Performing cleaning and maintenance on both machines is pretty much the same process. Just follow these tips.

  • Clean the exterior from time to time using a damp, soapy non-abrasive cloth
  • Empty and clean the drip tray occasionally
  • Clean the water reservoir in a dishwasher or hand wash, and then rinse it after cleaning to remove remains of cleaning solutions
  • Remove and clean the K-Cup holder and its parts
  • Descale the brewer every 3-6 months (when the descaling light turns on)
  • Run a cleaning cycle if you only want to get hot water from your coffee maker, this will help to eliminate coffee residues

Keep in mind that the water reservoir and drip tray can be washed in the dishwasher (top rack only), which makes the cleaning process even easier.

This feature is great for saving energy.

High Altitude Brewing

This function is only available for the K-Select.
