An espresso machine brews coffee by forcing pressurized water near boiling point through a "puck" of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso. The first machine for making espresso was built and patented in 1884 by Angelo Moriondo of Turin, Italy. An improved design was patented on April 28, 1903, by Luigi Bezzera. The founder of the La Pavoni company bought the patent and from 1905 produced espresso machines commercially on a small scale in Milan. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a grouphead and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids (such as milk) for coffee drinks such as cappuccino and caffe latte.
For all the debate over whether the best coffee comes from a Chemex or a French press or an AeroPress (even Nespresso), sometimes you just want to turn on a machine and let it do the work. We asked ten coffee drinkers — food-industry professionals and just plain coffee snobs — what’s the coffee machine that’ll get you a simple at-home brew without all the fuss?

Dual-boiler espresso systems are undoubtedly the gold standard for home or commercial equipment: They allow the machine to maintain the optimum temperature for simultaneously brewing espresso coffee (195–205 degrees Fahrenheit) as well as for creating steam (closer to 250 degrees Fahrenheit), which means no waiting around, watching your crema disappear while you wait to steam milk. The Breville also has programmable options for softly pre-infusing the coffee, and has a control valve that monitors extraction pressure—two things most home machines don't feature. If espresso is your go-to coffee every day, this is the machine for you.
CR’s take: If you need only one or two cups of coffee each morning and you don’t want a pod coffee maker, consider the Technivorm Moccamaster Cup-One Brewer. Compact and clean-lined, it has a profile that makes some sense of its high price (it retails for more than $200), and it’s a superstar when it comes to reliability. Technivorm was one of only three drip machine brands to earn an Excellent rating for predicted reliability in our member survey. Our testers also give this machine a strong score for brew performance. This model has only one simple feature (auto-shutoff) and it’s not the easiest machine to use, but you can count on it to last.

Pierce's design was later improved by U.S. appliance engineers Ivar Jepson, Ludvik Koci, and Eric Bylund of Sunbeam in the late 1930s. They altered the heating chamber and eliminated the recessed well which was hard to clean. They also made several improvements to the filtering mechanism. Their improved design of plated metals, styled by industrial designer Alfonso Iannelli, became the famous Sunbeam Coffeemaster line of automated vacuum coffee makers (Models C-20, C-30, C40, and C-50). The Coffeemaster vacuum brewer was sold in large numbers in the United States during the years immediately following World War I.
The built-in burr grinder is high quality, and you can easily adjust the grind size and amount with a dial on the front of the machine. You can choose to use either a single- or double-wall filter basket, and the grinder will automatically adjust to give you the right about of coffee grounds for your brew. Reviewers love that it comes with the grinder and praise its quality.
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.
