In recent years air-pump-driven espresso machines have emerged. These machines use compressed air to force the hot water through the coffee grounds. The hot water is typically added from a kettle or a thermo flask. The compressed air comes from either a hand-pump, N2 or CO2 cartridges or an electric compressor. One of the advantages of the air-pump-driven machines is that they are much smaller and lighter than electric machines. They are often handheld and portable. The first air-pump-driven machine was the AeroPress, which was invented by Alan Adler, an American inventor, and introduced in 2005. Handpresso Wild, invented by Nielsen Innovation SARL, a French innovation house, was introduced in 2007.

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.
Where MistoBox really shines is in its efficiently designed website and deep customization. If you want to, you can sign up for a scheduled delivery of curated espresso blends or single origin coffees and just let it ride—no input is necessary beyond the initial question of what kind of roast you like. But if you want to get a little more involved, you can rate each coffee you receive to refine future shipments or—if you want to take the future into your own hands—curate your own list of upcoming beans with a feature MistoBox calls the "Brew Queue." The number of choices is dizzying, and there are plenty of user reviews to guide your way thanks to a very active community.

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.
