Finding the best Keurig is simple – it’s all about a few key features. Let’s dive into the differences between the Keurig K-Slim and K-Express in this article.

Quick Comparison: K-Slim vs K-Express

Important Keurig Features

Cup size selection

Discover the world of Keurig coffee cup sizes! Depending on your machine, you might get to pick from up to five sizes, from a tiny 4 ounces to a big 12 ounces cup. But, if you have one of the smaller models like the K-Mini, K-Mini Plus, or K-Slim, there’s no size button. Instead, the amount of coffee it brews depends on how much water you pour into the tank.

All current Keurig models use the same pod size, affecting the taste depending on the brew size. Usually, the flavor stays rich up to 8 ounces. At 10 ounces, the coffee starts to taste weaker. And at 12 ounces, it’s too watery for most coffee fans.

Drip coffee and carafe

The K-Duo Keurigs aren’t just for single cups; they can whip up a whole carafe of drip coffee too. Choose from brewing 8, 10, or 12 cups at once. Plus, except for the K-Essentials, you can even go for a cozy 6 cups. Perfect for any coffee need!

The K-Duo and K-Duo Essentials come with a glass carafe, just like the ones you see on regular drip coffee makers. But, the K-Duo Plus steps it up with a stainless-steel thermal carafe. This cool feature keeps your coffee warm for hours, without that burnt taste you get when coffee sits too long on a warmer.

Water tank

Every Keurig comes with a water tank, but their sizes differ. Some, like the K-Mini and K15, are small and make just one cup at a time. Others, like the K-Supreme Plus models, hold up to 78 ounces, letting you brew 9 to 13 cups before needing a refill.

Newer Keurig machines come with detachable water tanks. This design not only simplifies refilling but also lets you wash the tank right in your sink for better hygiene.

The K-Supreme and K-Duo Plus make life easier with a water tank you can move. Whether you place it beside or behind the brewer, it’s perfect for small kitchens. Now, fitting your coffee maker into tight spaces is a breeze!

Strong button

Old Keurigs brewed weak coffee, but worry not! New models now offer richer cups. For those craving even bolder flavors, check out the Keurig strong button.

Hitting the strong button on your coffee maker adds about 30 seconds to the brew time. This extra moment lets the water soak up more oils, acids, and sugars from the coffee grounds, making your cup taste way better.

This feature is essential for drip coffee lovers. Learn more here.

Temperature control

Most Keurig machines heat water to 192 degrees Fahrenheit. But, if you fancy a bit more control, models like the K-Elite and K-Supreme Plus let you adjust the temperature slightly. For the K-Elite, you can choose between 187 and 192 degrees. However, the K-Supreme Plus doesn’t tell you the exact temperatures of its presets. 

This feature adds a nice touch for certain drinks, but many might not find it very useful.

Iced coffee

Turning hot coffee into iced coffee by simply pouring it over ice might seem easy, but beware—it often ends up too weak. Even using a Keurig on the strong setting doesn’t quite cut it; the ice dilutes the flavor too much.

The K-Elite and K-Supreme models all feature a special setting for perfect iced coffee.

Just like the special iced coffee option on top-notch Ninja coffee makers, this cool feature makes your coffee hot and strong. Why? So when you add ice, your coffee still tastes amazing and doesn’t get watered down. Enjoy a delicious iced coffee every time!

Lattes and cappuccinos

The Keurig K-Cafe and K-Latte make brewing lattes, cappuccinos, and regular coffee a breeze. Each comes with a milk frother – the K-Cafe’s is stainless steel, while the K-Latte features non-stick plastic. Perfect for coffee lovers!

They use regular k-cup pods and any milk works with their frothers.

MultiStream technology

Keurig’s new MultiStream technology is their biggest update yet, making coffee stronger and tastier than ever before. It’s a game-changer!

Keurigs use pressure to push water through the middle of a k-cup. But, coffee grounds at the pod’s edge might not get fully brewed. This means you miss out on some delicious flavors.

MultiStream technology transforms your coffee experience by using several water streams to evenly soak the coffee pod. This method makes sure every bit of coffee is used, resulting in a richer and more delicious brew.

Switching from a regular coffee maker? Try brewers with MultiStream technology like K-Supreme models. They’ll elevate your coffee experience beyond other Keurigs.

Fits travel mug

Older Keurig machines had a problem: they couldn’t fit a regular travel mug under their nozzle. But worry not! Every new Keurig model now lets you brew your coffee right into your travel mug.


Nearly every Keurig now comes with a handy auto-off feature. It powers down your coffee maker to save energy, either 5 minutes or 2 hours after use, based on the model.

Keurig K-Slim

The Keurig K-Slim stands out as one of the tiniest Keurigs, just a bit bigger than the K-Mini. This size difference gives it a bigger, detachable water tank. However, unlike the K-Mini Plus, it lacks a strong brew feature.

Keurig K-Express

The Keurig K-Express keeps things small and easy, skipping fancy features for simplicity. Plus, it’s one of the most affordable ways to get that strong brew option you love.

It has a detachable water tank, making refills and cleaning a breeze, unlike the K-Classic line.

Final Verdict

The K-Slim is sleeker and a bit smaller than the Express, but its deeper size might not fit all kitchen spaces. Its big water tank is perfect for those who drink lots of coffee. However, the K-Express stands out with its strong brew button, making it a top choice for those who love a rich, flavorful cup.

Looking for a compact coffee maker? The K-Slim and K-Express are Keurig’s basic models. But if you crave richer coffee and more options without sacrificing space, consider the K-Supreme and K-Supreme Plus. For an even smarter choice, explore the latest K-Supreme Plus Smart. Perfect for beginners eager to elevate their coffee game!
