The De'Longhi comes with a durable, high-quality stainless steel boiler which would serve you well over time. Other notable features include a swivel jet frother for easy cappuccino and latte prep, a dual-function filter holder that gives you a choice between ground coffee and pods, and a self-priming function which we recommend for the absolute best results.
As legend has it, Ethiopian goats were the first to discover the delightful properties of coffee beans when they ate the raw beans right off the stem. The goats nibbled happily away at the beans, probably right around 2 o'clock every afternoon, until finally an astute goat herder noticed the goats' perky behavior, gave the beans a taste, found them quite stimulating, and rushed them off to the nearest monastery.
If you're highly particular about how your coffee tastes, you'll want the Behmor Brazen Plus. It was the only drip machine we tested that brewed at the optimal temperature to bring out the best flavor from coffee beans. Getting this perfect brew takes a little more time to set up than most coffee makers require— before starting, you have to calibrate it for the altitude in your area— but overall it's easy to use.
It’s obvious, but easy to forget: If you don’t clean out your coffee machine’s carafe after each use with soap and water, you’ll always end up tasting a little bit of yesterday’s now-bitter brew. Thermal carafes need to be hand-washed, but all the plastic components of our top picks — brew baskets, lids, etc. — are dishwasher-safe if you keep them on the top rack.
No one wants to wait in line for espresso, right? This machine lets you make two shots at once, so you can make drinks for two in half the time, and you can choose a single- or double-shot portafilter for different serving sizes. The machine has a 15-bar pump system and a frothing arm to make a creamy froth for your cappuccinos and lattes. An indicator light lets you know when the process is complete.
Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.
The very first espresso machines worked on a steam-pressure basis, and they’re still in use today. With this type of machine, steam or steam pressure is used to force water through the coffee grounds and produce espresso. Some steam-driven machines can produce a measure of foam “crema.” But they can’t generate enough pressure or provide the precise temperature control necessary to produce true espresso: They simply make a very strong cup of coffee. However, they cost considerably less than pump-driven machines. Our verdict is that if you’re a true espresso lover and seeking to make a good shot at home, we recommend you steer clear of steam-driven machines. They’ll likely disappoint you.
Why it's great: As much as we appreciate freshly ground coffee beans for our espresso, let's be honest: when you *accidentally* snooze your alarm (five times) in the morning and don't even have time to brush your hair, chances are the last think you're gonna think about doing is grinding some freakin' beans. This could be a problem if you're someone (like me) who can't function without a strong dose of caffeine in the morning. However, not a problem with Nespresso. This life-saver heats up in less than 15 seconds and gets you tasty espresso at the push of a button. You get your quick fix without sacrificing quality. 
In terms of maintenance, more complex machines tend to require more cleaning. Accessories like pumps, boiler setups, and thermostats usually forecast the amount of cleanup and maintenance that will be required over time. Buyers should be aware that machines with plastic outer coatings can crack with repeated use, leading to the need for expensive repairs or even replacement.
Whole bean coffee that you grind yourself is preferable to pre-ground, too. The bean’s exterior traps and protects all of the delicate, volatile, and water-soluble oils that give coffee its flavor. As soon as you break the protective shell, it’s easy for the flavor to get contaminated, and much of the aroma escapes as soon as the oils are exposed to air.
Our brew-performance tests measure the brew temperature and contact time (how long water stays within a sweet spot of 195° to 205° F for brewing). We measure concentration using a refractometer, a device that measures the amount of coffee dissolved in each brew. Our convenience tests look at how easy it is to set timers, fill the reservoir, clean the machine, and more. And for the first time, we’re incorporating predicted reliability and owner satisfaction ratings into the new Overall Score for each model. We determine these ratings for each drip coffee maker brand using survey data collected from thousands of CR members.
