The Keurig K-Supreme Coffee Maker is a very nice evolution of the traditional Keurig single cup pod brewer. It is a very attractive unit, slim and elegantly styled in silver and matte black. It introduces several great new features and utilizes an innovative brewing system to extract maximum flavor from K-cups.
Keurig was founded in Boston, Massachusetts in 1992. “Keurig” is Dutch for “elegant and neat” and chosen to describe their new single cup coffee-making process. The founders of the company invented the K-Cup and designed coffee makers which utilized the K-Cup to brew excellent coffee, one cup at a time, first in offices, then expanded to the home market. The secret of the K-Cup’s flavor is specially ground coffee held in a filter within the plastic K-Cup, which is pumped full of nitrogen and sealed with a foil cover to preserve freshness until use. Keurig has sold nearly 100 million K-Cup coffee makers during its existence. Today Keurig is part of a $13 billion public company which also owns Green Mountain Coffee, Dr. Pepper and Snapple.

I have used the classic Keurig B70 Platinum as my primary coffee maker for the past twelve years and it has produced over 8,000 cups of great coffee for me during that time. The new K-Supreme has some really big shoes to fill in replacing that reliable workhorse.
When you unbox the Keurig K-Supreme you should be very impressed by the elegant design and the quality of construction. It is a beautiful combination of matte black and silver surfaces, accented by a crystal clear water reservoir. All controls are on the top, above the K-Cup basket. The cup holder/drip tray slides out to allow you to fill tall travel cups.
One dominant impression is how slim this new brewer is, barely wider than a coffee cup. The water reservoir is located on the left side normally, but by just releasing a locking tab the water reservoir can be easily relocated to the rear of the unit. This makes the already slim coffee maker even more svelte – just 4.8 inches wide! And it is really not much deeper, just 14.6 inches compared to 11.4 inches deep with the reservoir on the side. If you have limited counter space this is a wonderful feature and only this Keurig model has it.
If you have an older Keurig you are used to bringing water to the coffee brewer for refilling because lifting off and replacing the old style water reservoir is a bit awkward. The new K-Supreme has ended that problem – the 66-ounce water reservoir has a nice handle and is well-balanced which facilitates easy removal and refilling. This also encourages more frequent cleaning of the water reservoir.
One nice improvement on the K-Supreme compared to my older Keurig is that you no longer have to reach behind the machine to turn it on. Power is activated when you swing up the top to insert the K-Cup. Also, you do not have to wait while the brewer heats the water (which the older machines require.) Just insert the K-Cup, lower the top, select the cup size, press the “K” brew start button and the brewing process starts. I measured the brewing time for a 12 ounce cup from my old and new Keurigs. Starting from cold, the B70 required one minute to heat the water before it would allow brewing to start, then took 50 more seconds to actually brew the coffee. The K-Supreme started immediately and completed a 12 ounce cup of coffee in one minute and 35 seconds. I should note that a second cup of coffee from the older B70 machine required only one minute since the water had already been heated. So if you are making one cup of coffee the new K-Supreme is quicker, but two cups are completed a bit faster using the older machine.
The biggest change in the K-Supreme brewer is the new Multi-Stream technology. Studies have shown that the key to extracting maximum flavor and strength from coffee grounds is a combination of dwell-time (how long the water is in contact with the coffee), temperature (high but not too hot) and turbulence (how thoroughly the water mixes with the coffee). All prior Keurig brewers utilized a single needle to inject water into the K-Cup. The new Multi-Stream system uses five needles to inject water into the K-Cup simultaneously. This increases turbulence and extracts more flavor. In addition to this change, the K-Supreme has a “Strong” option. This seems to add dwell time to the brewing process.
So how well does it work? Just great! I compared Starbucks Pike Place coffee prepared on the new K-Supreme to that prepared on my trusty B70 Platinum. The new brewer produced a richer 12 ounce cup of coffee and the strong option did just that – made it stronger. However, I took the process a step further. I made a 6 ounce cup of coffee using a pod, then removed that pod, rotated it 180 degrees and reinserted that same pod and brewed a second 6 ounces into the cup. The result was even better than a single brew into a 12 ounce cup. Rotating the K-Cup added a second drain point on the bottom of the K-Cup and seemed to add more strength to the brewed coffee. The downside is that this nearly doubles the brewing time.
My B70 has a temperature control and I have it set at 192 degrees (the maximum). The K-Supreme does not have a temperature control. So I measured the temperature of the coffee produced and it was the same for both machines – 180 degrees! I suspect that either the process of brewing the coffee lowers the water temperature a bit or my older machine needs to be decalcified. In any event, the temperature is fine for producing a great cup of coffee.
One other difference between the older Keurig brewer and the new K-Supreme is that the latter is much quieter. It completes the full brewing cycle without all of the hissing, boiling and water-pumping noises of the older machines. This is a nice improvement and might make the process of preparing that first cup of coffee early in the morning a little less stressful!
The K-Supreme also has an “Over Ice” option. This lowers the brewing water temperature to the minimum level required to accomplish the process and fixes the volume at 6 ounces. This is perfect for filling a glass which has ice cubes and the lower temperature will not melt all of the ice.
Other notes: There are two lights on the top, near the control buttons. One signals when the water level is low and the other advises that descaling is recommended. The latter occurs after 250 cups have been brewed. The descaling process is automatic when you press the 8 ounce and 12 ounce buttons simultaneously for three seconds, then press the “K” brew button. To save energy the unit shuts off five minutes after a brewing cycle. Finally, be careful – never put any of the removable parts (water reservoir, drip tray) into a dishwasher – they will not survive! Hand wash only!
There is really only one (minor) negative I can note about this coffee maker. Each time you brew a cup of coffee you have to select the cup size. It does not remain on the last size chosen like my old Keurig. But this is a very small quibble and the fact that it is my only complaint speaks very well about this great device.
The new K-Supreme certainly meets the “elegant and neat” criteria chosen by the company’s founders when they chose the name, “Keurig” and this wonderful and evolutionary coffee maker has fully earned a full five stars and my very strong recommendation.
