Keurig K-Duo vs K-Duo Plus: What's The Difference? [Updated For 2022]

Keurig Duo vs Duo Plus — what's the difference?

If you're looking for a versatile Keurig coffee maker capable of brewing both single servings and larger pots, then you're in the right place.

Both the K-Duo and K-Duo Plus feature two separate brewing systems to give you extra control over your morning coffee routine:

  • Single-serve system that brews K-cups
  • Full-sized system that brews standard ground coffee

(By the way, there's a third Duo brewer called the K-Duo Essentials. We'll include it in our comparison too.)

Which two-in-one coffee maker is right for you?

Let's get started.

Similarities

Keurig makes three versions of their K-Duo brewer:

Before we look at the differences, let's take a look at what all three machines have in common:

Water reservoir60 oz
DisplayButton controls only (Brew Strength, Brew Size, Auto-On) + digital clock display

Differences

The K-Duo Essentials and K-Duo Plus are upgraded versions of the base K-Duo brewer. Here's how all three compare:

FeatureK-DuoK-Duo EssentialsK-Duo Plus
6 oz brew sizeNoYesYes
Strength controlNoYesYes
Swivel water tankNoNoYes
CarafeGlassGlassThermal

Again, both the K-Duo Essentials and K-Duo Plus add onto the base K-Duo:

  • K-Duo Essentials: Adds 6 oz brew size + Strength Control
  • K-Duo Plus: Adds 6 oz brew size + Strength Control + swivel water tank + thermal carafe (instead of glass)

Pretty simple stuff, right?

Now, the most important question...

Keurig K-Duo vs Essentials vs Plus: Which Is Right For You?

If all you're looking for is a two-in-one Keurig coffee maker, especially if you don't need the smallest 6 oz brew size, then go with the standard K-Duo.

If the 6 oz brew size or Strength Control feature are appealing, your choice is between the K-Duo Essentials and K-Duo Plus. Personally, I'm not a fan of glass carafes — they break too easily and the warming plate burns the last few cups of coffee — so the K-Duo Plus is a clear winner (in my opinion) and worth the small price jump.

If you don't need the thermal carafe or swivel water tank, which helps it fit better on your counter and makes refilling easier, then don't hesitate to get the K-Duo Essentials.

I'm Bryan but most people know me as The Coffee Maven. I grew up outside Boston, Massachusetts and received my Bachelor's degree in Biochemistry from Providence College. My first introduction to coffee was during my college days, when I used it as a source of caffeine to fuel late-night study sessions, but soon I became obsessed with the chemistry of coffee. How did changes to water temperature or contact time affect its taste? Why do beans from Africa taste fruity while beans from Indonesia taste spicy? I launched The Coffee Maven in February 2017 to explore these questions and help others brew their perfect cup. Welcome to my site, and thanks for reading!
