Reviewing the Keurig K-Supreme Plus vs K-Supreme

In this section, we’ll go into the nitty-gritty regarding the Keurig K-Supreme vs the K-Supreme Plus to help you decide which one is a better fit for you.

Brew Sizes

The Keurig K-Supreme brews single cups of coffee in 6, 8, 10, and 12-ounce sizes. The K-Supreme can brew back-to-back cups of coffee, immediately, without the need to wait for reheating.

In addition, the machine can accommodate travel mugs up to seven inches tall by removing the drip tray.

The Keurig K-Supreme Plus is similar but adds a 4-ounce brew size option. It, like the K-Supreme, can brew back-to-back cups of coffee without waiting for reheating, and can also accommodate travel mugs up to seven inches tall.

Winner: Keurig K-Supreme Plus

Water Tank

The Keurig K-Supreme comes equipped with a 66-ounce dual-position reservoir. This means that the water reservoir can be placed both on the side of the machine and on the back. 

The 66-ounce reservoir is large, capable of brewing eight cups of coffee without refill (at the 8-ounce brew size). 

The Keurig K-Supreme Plus comes with a massive 78-ounce single-position water reservoir. This allows you to brew nine cups of coffee without refilling (at the 8-ounce size). 

Unlike the K-Supreme, the reservoir on the K-Supreme Plus can not be placed in multiple positions. This could be an issue in smaller, less adaptable kitchens. However, the extra 12 ounces is super convenient, and gives the K-Supreme Plus the win here.

Both water reservoirs are compatible with charcoal filters, which is great if you want to brew coffee with even cleaner water.

Winner: Keurig K-Supreme Plus

Brew Strength

The Keurig K-Supreme brews coffee in two different strengths, regular and bold. The bold setting brews stronger coffee by percolating the water through the grounds at a slower pace.

This allows for more flavorful coffee because the water has more contact time with the grounds. 

The Keurig K-Supreme Plus offers three different brew strengths, which further adds to the user experience by allowing you to personalize the coffee to your tastes. 

With both machines, there is a noticeable difference in coffee strength, flavor, and boldness between the different strength options. The Keurig K-Supreme Plus just takes it a step further.

Winner: Keurig K-Supreme Plus

Brewing Time

For each machine, brewing time varies based on the brew size and strength controls. 

For both machines, the heat-up time is negligible, with coffee beginning to come out in around twelve seconds

On the K-Supreme, at the standard 8-ounce brew size, both the regular and bold options are done brewing in under 1.5 minutes. The bold setting takes a little while longer than regular brewing. 

On the K-Supreme Plus, at the standard 8-ounce brew size, the regular and second strength options are both done in under 1.5 minutes. At full strength and temperature, brewing takes around one minute and fifty-five seconds. 

This extra time allows for better extraction through further contact time and results in a better cup of coffee. 

Winner: Tie

Coffee Flavor

The Keurig K-Supreme and Supreme Plus are both some of Keurig’s more premium machines. As such, the flavor you get from the coffee is bound to be good.

The K-Supreme uses five needles instead of one to inject water into the pod for extraction. This results in more flavorful coffee, as the water is flowing evenly through the whole pod, taking advantage of all coffee and surface area.

Brewing with the bold option helps bring out more subtleties and nuanced flavor in the coffee. Overall, the coffee was really good.

The K-Supreme Plus also uses five needles for extraction and brews excellent coffee. With three strength and temperature controls, there’s bound to be something that fits your tastes. 

Both machines are calibrated excellently, and flavor profile integrity is preserved. Overall, the coffee on both these machines tastes excellent. 

Because of the extra strength option, the K-Supreme Plus comes out on top, however slightly.

Winner: Keurig K-Supreme Plus

Temperature Control

There are a few different reasons why temperature control is important on a machine, the first being preference. A person could prefer hotter or cooler coffee. In addition, different water temperatures are optimal for brewing coffee at different altitudes.

The Keurig K-Supreme offers very limited temperature control features. While you cannot adjust the temperature based solely on preference, the machine does have a high altitude setting. 

This lowers the water temperature to prevent damage to the internal components of the machine, as the water boils at a lower temperature at higher altitudes. 

The Keurig K-Supreme Plus offers 3 temperature settings to choose from in addition to an altitude setting, better catering to people who like their coffee hotter. 

Winner: Keurig K-Supreme Plus

Dimensions, Design, and Weight

The Keurig K-Supreme and K-Supreme Plus are very similar in size and weight.

These are the dimensions of the K-Supreme:

  • Height: 12.2” (17” when open)
  • Width: 7.9”
  • Depth with water reservoir on side: 12”
  • Depth with water reservoir in rear: 15.1”
  • Weight: 8.1lbs

These are the dimensions of the K-Supreme Plus:

  • Height: 12.2” (16.9” when open)
  • Width: 8.3”
  • Depth: 13.3”
  • Weight: 8.3lbs

Some have noted that the handle of the K-Supreme Plus feels a bit softer and sturdier.

Also, the K-Supreme Plus has more metal parts, while the K-Supreme is mostly plastic.

Although they are very similar in design, we find the K-Supreme Plus to be more robust, making it the clear winner.

However, the K-Supreme might be better for some people since it can be more compact when the water reservoir is located at the rear.

Additional Features

There are a few additional feature differences when looking at the Keurig K-Supreme vs K-Supreme Plus.

Over Ice Mode

Both coffee makers come with an Over Ice mode which is designed to brew at a lower temperature, optimized for brewing iced coffee.

Keep in mind that when this mode is enabled you will only be able to brew 6oz of coffee.

Hot Water On Demand

You can dispense hot water with both coffee makers for making hot beverages like tea or other things like oat meat.

To do this you just have to follow the normal brewing process but without adding a K-Cup capsule.
