A refinement of the piston machine is the pump-driven machine, which was introduced in the Faema E61 in 1961, and has become the most popular design in commercial espresso bars. Instead of using manual force, a motor-driven pump provides the force necessary for espresso brewing. Espresso machines are made to accept water directly from a cold water line supply, common in commercial installations, or from a separate tank that must be filled with water by hand. The latter is more common with lower-volume commercial installations and domestic espresso machines. Due to the required high pumping pressure and precision flow control needed, the particular type of electric pumps typically used are known as solenoid-piston pumps. These pumps are classified as a positive displacement type (general category) of pump.
“My mom gave me a Gevalia 12-cup, programmable coffee maker a few years ago, and it’s gone with me through multiple Brooklyn apartments. It’s hard to find now, so if it ever breaks, she has a killer Cuisinart DCC-1200. I actually look forward to her coffee every time I’m home. It makes a mellow brew. If my Gevalia machine ever gives out on me, I’ll upgrade to that.” — Allie LaPorte, wine representative, Wilson Daniels
‡Pre-Infusing: Pre-infusing is a technique where the dry coffee grounds are initially saturated with hot water, allowing a “bloom” of carbon dioxide to escape. This 45-second(ish) process puts hot water into contact with more surface area around each ground throughout the brewing process, as it’s no longer competing with the escaping gas bubbles. It can improve the quality of the final product, since this more uniform contact creates a more even extraction. It’s a feature that six of the 10 pots we tested incorporated into their designs — as well as all four of our top picks.
Thankfully we have Amazon, and moreover Amazon users (aka fellow espresso connoisseurs) who happen to be very vocal when it comes to their favorite machines. (We have read dozens of reviews and these folks are THOROUGH, to say the least.) To save you some time, we put together a list of the best espresso makers based on Amazon reviews. Our number one favorite was the Breville BES870XL. Not only does it take the spot of "best of the best" on Amazon's ranks page, its ease of use, freshness factor, and straight up *amazing* espresso-making capabilities have reviewers swooning.
The gist: The Nespresso Inissia is very similar to the Pixie. It also comes with one-touch options for either a single espresso or lungo cup size. It pumps with 19 bars of pressure and also heats up in less than 25 seconds. With over 2,500 reviews, it stands out with a 4.4 star rating on Amazon. The Inissia has more or less the same internal workings as the Pixie (including the 0.7 liter water tank), so the quality of espresso produced should be pretty identical. The difference: unlike the Pixie, which is made of metal, the Inissia's exterior is mostly plastic and has a slightly funkier design. However the Inissia comes in several colors, including red, black, silver, and titan.
The Mr. Coffee DRX5 coffee maker gives you the advanced action to delay-brew your coffee, enabling you to wake up to coffee waiting for you. The auto pause and grab a cup option allows you to get a cup of coffee before the brew cycle is finished, with the machine halting the brewing process so you can pour a cup and then complete the process once you reinsert the carafe into the chassis.
"A rare example of the meeting of form and function. This machine is both beautiful to look at and makes wonderful delicious espresso and cappuccino. I was hesitant to spend this much on a "coffee maker", but took into consideration what it costs to get a decent cappuccino from a cafe or Starbucks and finally gave in. Boy am I glad I did. All it takes to get me out of bed in the morning is the happy thought of pulling yet another delicious shot from this wonderful machine."
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.
