Quick Verdict
The Best K-Cup Brewer for People Who Want Control
Best for: Single-serve lovers who want full customizationThe Keurig K-Supreme Plus is the most customizable standard Keurig on the market. With MultiStream Technology extracting more flavor from each pod, five brew strength settings, and three temperature levels, it gives pod-coffee drinkers a level of control previously only available in more premium machines. The 78oz reservoir is generous, and the iced coffee mode is genuinely useful.
What is MultiStream Technology?
MultiStream Technology is Keurig's most significant pod brewing innovation in years. Where older Keurig machines used a single needle to pierce the K-Cup pod and push water through, the K-Supreme Plus uses five separate needles arranged to saturate the grounds from multiple points simultaneously.
The result is more even extraction. With a single needle, much of the water channeled through the pod follows the path of least resistance — meaning some grounds get over-extracted while others barely get wet. MultiStream's five-point saturation forces water through the entire puck more uniformly, which produces a noticeably fuller cup with better clarity at the edges.
In side-by-side testing with a standard Keurig K-Classic using the same pod, the K-Supreme Plus consistently produced a slightly richer, slightly less flat-tasting cup. The improvement is real, though it won't transform low-quality pods into something spectacular — the pod quality still matters most.
Strength and Temperature Settings
5 Strength Settings
The K-Supreme Plus offers five discrete brew strength levels: 1 (mild), 2, 3, 4, and 5 (extra bold). The difference between level 1 and level 5 is substantial — not just a slightly darker color, but a genuine shift in body, intensity, and aftertaste. Most users settle on levels 3 or 4 for a satisfying cup. Level 5 combined with the 8oz brew size produces something close to a strong double-strength cup.
3 Brew Temperatures
Three temperature settings — low (187°F/86°C), medium (192°F/89°C), and high (197°F/92°C) — let you optimize extraction for different pod types and personal preference. Lighter roasts tend to benefit from the high temperature setting. If you're sensitive to acidity, medium or low can soften the sharper notes in bright or fruity pods.
78oz Reservoir
The 78oz removable reservoir is among the largest in the standard Keurig lineup. For a single person who brews two cups daily, this means roughly five to six days between refills. The reservoir slides off the back of the machine and is easy to rinse. One minor annoyance: the water level window is relatively small and can be hard to read at a glance.

Frequently Asked Questions
What is MultiStream Technology on the Keurig K-Supreme Plus?
MultiStream Technology uses five needles to saturate K-Cup pod grounds from multiple points simultaneously, producing more even extraction and a fuller-tasting cup compared to single-needle older Keurig models.
Can the Keurig K-Supreme Plus brew ground coffee?
Only with a reusable K-Cup filter (sold separately). It does not have a native grounds basket like the Ninja DualBrew Pro. For a machine that natively handles both, see our Ninja DualBrew Pro review.
How big is the reservoir?
The K-Supreme Plus has a 78oz removable reservoir — one of the largest in the standard Keurig lineup. For a person brewing two cups a day, that's roughly five to six days between refills.
Does the Keurig K-Supreme Plus make espresso?
No. It brews single-serve drip coffee. Even the extra-bold setting does not produce true espresso. For real espresso in a pod machine, see the Nespresso VertuoPlus review.
