Keurig Supreme vs Keurig Supreme Plus

This is my comparison of the Keurig K Supreme vs Keurig K Supreme Plus, two of Keurig’s higher-end single-serve coffee machines.

I own the Supreme Plus and spent half a day researching the Keurig Supreme to find out the differences between the two machines.

Since the Supreme Plus is meant to be an upgrade of the Supreme, and this is reflected in the prices of the two machines, I will be paying particular attention to whether the Supreme Plus justifies its additional cost over the Supreme.

Let’s get started.

Should I Buy the Keurig K Supreme or K Supreme Plus (Quick Verdict)?

I would recommend buying the K Supreme Plus over the K Supreme. The Supreme Plus makes far better coffee than the Supreme due to the fact that it gives you greater control over brewing time and temperature.

Although there is not much between the two machines other than the quality of coffee they produce, since coffee quality is so fundamental to a machine’s overall performance this alone justifies the additional cost of the Supreme Plus.

Differences between Keurig K Supreme and Keurig K Supreme Plus

The key differences between the Supreme and the Supreme Plus are:

  • The Supreme Plus has an additional strength setting over the Supreme and allows you three temperature settings. The Supreme only allows you to brew at one temperature.
  • The Supreme Plus allows you to brew 4 oz serving sizes; the Supreme’s minimum serving size is 6 oz.
  • The Supreme Plus allows you to preset coffee types. The Supreme makes you program each coffee that you make from scratch.
  • The Supreme Plus has a 6 oz larger reservoir than the Supreme.
  • The Supreme lets you adjust its reservoir position. You can either have it on the left or on the back of the machine. The Supreme Plus has its reservoir fixed on the left of the machine.

Let’s now take a closer look at how these differences affect the quality and usability of each machine.

Quality of Coffee

The Supreme Plus makes significantly better coffee than the Supreme. This is due to its additional strength settings which lengthens the Plus’s brewing time compared to the Supreme. The Supreme Plus can also brew coffees at a higher temperature than the Supreme which allows you to make a strong coffee at higher serving sizes.

The two factors that differentiate the way that the Supreme and Supreme Plus make coffee are their brewing times and brewing temperatures.

Brewing Time

The brewing time of each machine is controlled by the strength setting that you program.

The Keurig K Supreme offers you two strength settings. This is controlled by the “strong” button which you either press on or keep off prior to brewing.

The Keurig K Supreme Plus has three strength settings. 

The Supreme Plus’s lowest setting is equivalent to the Supreme with the “strong” button off. 

The Plus’s middle setting is equivalent to the Supreme with the “strong” button on, and its highest strength setting will brew your coffee for about 20 seconds longer than the Supreme will with the “strong” button on.

You can find a table of how strength setting affects brewing length below:

Machine and Strength SettingApprox Brewing Time 
Keurig K Supreme with “strong” button off60 seconds
Keurig K Supreme with “strong” button on80 seconds
Keurig K Supreme Plus on lowest strength setting60 seconds
Keurig K Supreme Plus on middle strength setting80 seconds
Keurig K Supreme Plus on highest strength setting100 seconds

In short, the Keurig Supreme Plus can make stronger, fuller-bodied coffees than the Supreme due to its additional brewing time.

Brewing Temperature

The Keurig K Supreme has one brewing temperature.

The Keurig K Supreme Plus has three temperature options. 

The Plus’s middle temperature is equivalent to the temperature that the Supreme brews at. 

The Supreme Plus can therefore brew coffees at a slightly higher and lower temperature than the Supreme, depending on the temperature option that you select.

The Supreme Plus’s higher brewing temperatures improve the quality of coffee at higher serving sizes. The Supreme Plus makes a good 10 oz coffee with a reusable K cup at 10 oz. With the Supreme, coffees of this size are a bit on the watery side.

Both machines can take standard and reusable K cups. Standard K cups only hold enough coffee for 6 oz servings, and reusable K cups can hold enough for 9.6 oz servings. 

Below is a table that shows the quality of coffee that each machine produces at certain serving sizes:

Quality of Coffee Winner: Keurig K Supreme Plus

The Supreme Plus can make the exact same coffees as the Plus and can also make stronger coffees. The Plus’s additional brewing times and temperatures allow you to make better coffee than the Supreme at larger serving sizes.

Ease of Use

The Keurig K Supreme Plus is marginally easier to use than the Supreme. Both machines are very intuitive (as are all Keurig machines – it’s something they do really well). The only difference between the two machines as far as ease of use goes is that the Keurig K Supreme Plus has three pre-programmed settings which allow you to brew your favourite drinks with two clicks.

Both of these machines are really easy to use, with control panels that have a dedicated button for every functionality. The “eligible” buttons at each stage of making coffees flashes so you are left in no doubt about what you need to press.

You can see what the Supreme Plus’s control panel looks like below:

The machine is asking me to select a serving size, as evidenced by the fact that only the serving-size buttons are illuminated.

The only real difference between the two machines as far as ease of use is concerned is that the Supreme Plus allows you to set three pre-programmed settings.

These pre programmes “remember” your selected brew strength, temperature and serving size, meaning all you need to do is select the preset and press brew.

The Keurig K Supreme does not have this feature, meaning that you need to programme each coffee you make with the machine from scratch. 

Although this is more effort, the machine is so easy to use that I don’t think it makes a big difference to the comparative usability of the machine overall.

Even though the Supreme Plus has many additional brewing options over the Supreme, it makes it easy for you to know which options you have selected by having a digital display which tells you what temperature and strength settings you have selected.

The digital display will also tell you when the Supreme Plus needs to be descaled.

The Supreme does not have this digital display, but given its more stripped-back range of brewing settings, I don’t think it really needs one. The machine will still tell you when it needs to be descaled by flashing its descale light.

Both machines have a tall, pitcher-style reservoir with a handle. This makes it very easy to fill up without spilling.

I usually like to review the ease of cleaning of machines when evaluating ease of use, but the cleaning of these two machines is identical, so I won’t dedicate a whole section to it.

Here are the parts of the machines that need to be cleaned:

  • The reservoir, K cup port and drip tray can be removed and cleaned in the sink (they are not dishwasher safe)
  • Machines go into descale mode every 250 brews. In descale mode, it needs to make a 12 oz brew with either descaling solution or white vinegar
  • The K cup port holder of both machines should be sponge cleaned when the K cup port is removed as grinds and coffee fall in here.

I find that the Supreme Plus needs to be descaled more often than every 250 brews, especially if you use it daily. 

You can descale a machine when not in descale mode by running a 12 oz brew with descaling solution/white vinegar in the reservoir and without a K cup in the port.

As both machines go into descale mode every 250 brews, both machines will require descaling more often than they say they do.

Ease of use Winner: Keurig K Supreme Plus (but only just)

The Supreme Plus’s preprogrammed settings make it a faster machine to make coffee with than the Supreme. That being said both machines are very easy to use and clean.

Size and Aesthetics

The Keurig K Supreme is a slightly smaller machine than the Supreme Plus. Its movable reservoir makes it a better choice for people where limited countertop space is a concern.

Keurig K Supreme allows you to move its reservoir from being attached to its left to being attached to its rear. This means you can adjust its footprint depending on what space is on your countertop. 

I am not sure why the Supreme Plus abandoned this feature, but its reservoir is fixed on its left side.

When both machines have their reservoir on their left side the Supreme Plus is still roughly half an inch taller, wider and deeper than the Supreme. Again if you are concerned about limited countertop space the Supreme may be a better option than the Supreme Plus.

The Supreme Plus has a metal finish on the front of the machine (see image below). The Supreme has a plastic finish which comes in black, white or gray.

Size and Aesthetics Winner: Keurig K Supreme

Although the Supreme Plus looks better than the Supreme, I’m giving this to the Supreme as it is more flexible for crowded countertops.

What do the Keurig K Supreme and K Supreme Plus Have in Common?

Here is a list of what the Keurig K Supreme and K Supreme Plus have in common.

  • Both use multistream technology, meaning that K cups are punctured with five needed for more even extraction.
  • Both machines have an over-ice setting that works in the exact same way.
  • Both machines have a very high build quality by Keurig machine standards and should last a lot longer than Keurig’s smaller machines (like the Mini, Mini Plus and Express).
  • Both machines take reusable K cups (just make sure they are multistream compatible)
  • Both machines are compatible and are sold with, Keurig’s charcoal water filters.
  • Both machines force you to descale after 250 brews.

If any of these features are the most important things that you look for in your Keurig machine then you might want to opt for the cheaper Keurig K Supreme.

Keurig Supreme vs Keurig Supreme Plus: Final Verdict

The Keurig Supreme Plus justifies its additional cost compared to the Keurig Supreme for one simple reason: it makes better coffee.

This is the most important aspect of a coffee machine, so therefore I would recommend purchasing the Keurig Supreme Plus over the Supreme.
