Unlike drip coffee makers, Keurig® single-serve coffee makers brew one serving at a time, so every cup is guaranteed fresh. This is especially true when you use K-Cup® pods. Their vacuum-sealed design locks out air to preserve the flavor and aroma of the freshly roasted and ground coffee beans inside.

Like Tassimo, Nespresso and Keurig machines focus on single-servings (one cup) of coffee. Where they differ is in that the Keurig can also make tea, hot chocolate, and other hot drinks, while the Nespresso only brews coffee, espresso, and cappuccino (in models with milk systems). Keurigs cannot brew espresso.

It depends on your needs. However, Keurig cannot make true espresso. A semi-automatic or super-automatic espresso machine is recommended for better quality espresso at home. If you enjoy a nice cafe-au-lait or coffee with milk, this may be the machine for you.

Making tea in a Keurig is possible, as this type of single-serve hot beverage station can be used as a hot water dispenser. To proceed, place your tea bag or infuser in a properly-sized mug that will fit under the dispenser and on the drip tray. Select the “dispense water only” brew cycle.

Single Serve Machines versus Carafes One of the main differences between Keurig and drip coffee makers is the serving size options. Keurig machines are designed as single-serve coffee makers, utilizing K-Cups to provide users with a convenient and quick way to brew a single cup of coffee.

K-cup coffee machines and capsules are available in Europe now. You can easily find these items on Amazon, the brand name is Dolché.

Every Keurig machine we tested brewed watery, flavorless coffee that paled against every other kind of coffee we've made at home. At its best, Keurig coffee tastes like diner coffee. At its worst, it tastes like hot brown water. In our testing, we found that only the 6 ounce brew size made coffee that tasted okay.

No is the short answer. You can't just put one type of cup/pod inside the other and expect them to work at all, because they're different shapes and sizes. Hell, a K-cup won't even fit inside a Nespresso machine, so that's a non-starter.

But depending on what type of Keurig you own, you can customize the strength of your coffee for espresso-style drinks. If you're looking for an espresso maker, we highly recommend the Breville Bambino Plus.

And the other two percent will be caffeine and oil extract from your course or ground beans. So you can imagine how light it tastes.

Keurig brews coffee and tea at with the water temperature of around 192°F. This is suitable for most black teas, many green teas and oolong teas. Because Keurig doesn't allow you to steep the tea, but rather just runs the hot water through the leaves, some tea types may be more appropriate.

So some Keurigs have single a single needle on top. And some Keurigs have multi-brew technology on top they've got five needles. They operate exactly the same way they're going to inject.

The Keurig K-Cup pods are less expensive, averaging from as low as $0.35 to as high as $0.65 per serving. Due to its larger pod sizes, the Nespresso VertuoLine now costs $0.90 to $1.35 per serving. With Keurig, you'll have the option of a reusable filter, which allows you to brew with your own ground coffee.

All About Nespresso Nespresso capsules come in a wide range of flavors and intensities, and can make standard cups of coffee, espresso shots and specialty drinks, like lattes and cappuccinos. Designed with style in mind, Nespresso offers sleek and modern designs that bring a touch of European elegance to a kitchen.

In Asia, both tea and coffee are available in K-Cups and can be brewed using the Keurig system. At this time, Keurig is sold in North America, Japan and select Asian countries.

K-Cups are filled with ground coffee, but there are a few major differences between the contents of the capsules and the ground coffee you'd buy at the store. The "roasting and grinding is a very different process in order to achieve the same style brewed cup," Zohar said.
