The principle of a vacuum brewer was to heat water in a lower vessel until expansion forced the contents through a narrow tube into an upper vessel containing ground coffee. When the lower vessel was empty and sufficient brewing time had elapsed, the heat was removed and the resulting vacuum would draw the brewed coffee back through a strainer into the lower chamber, from which it could be decanted. The Bauhaus interpretation of this device can be seen in Gerhard Marcks' Sintrax coffee maker of 1925.
In 1901, Luigi Bezzera of Milan patented improvements to the machine. Bezzera was not an engineer, but a mechanic. He patented a number of improvements to the existing machine, the first of which was applied for on the 19th of December 1901. It was titled "Innovations in the machinery to prepare and immediately serve coffee beverage" (Patent No. 153/94, 61707, granted on the 5th of June 1902). In 1905 the patent was bought by Desiderio Pavoni who founded the La Pavoni company and began to produce the machine commercially (one a day) in a small workshop in Via Parini in Milan.
If you push the 54mm stainless steel portafilter into the hands-free grinding cradle, the grounds will go right into the filter. The grinder shuts off when it's done, too, so you don't have to worry about figuring out if you've got the right amount. Finally, the included 54mm tamper ensures that your grounds are evenly pressed, so you get the most out of your beans.

If you don’t have the time or want to build a highly customized taste for your espresso mixes and just want a great tasting cup of espresso, super-automatic espresso makers are going to be your best bet. While you do give up some of the control you have over the final product, a super-automatic espresso maker automates almost all of the process for you, meaning that you can just get a great shot of espresso without having to do any extra work. This makes it perfect for people on the go or who prefer convenience over control.
†Programmable Brew Time: Conventional wisdom frowns at grinding beans early and programming a pot to brew later. The aromatic compounds in coffee beans start to oxidize as quickly as 15 minutes after grinding, which causes coffee to start losing aroma and flavor. But Michael Ebert, senior consultant at Firedancer Coffee Consultants, LLC, assured us that, given the trade-offs for convenience, “grinding the night before will still make a great coffee — just not as great as it could be.” Seven of the 10 pots we tested are programmable, including three of our top picks (all but the Bonavita).
This Good Housekeeping Seal star features an all-black body, a 12-cup glass carafe, a reusable filter and a backlit LCD screen with digital touchpad controls. You can program the clock to automatically brew coffee in the morning. It'll make a hot pot very quickly, but drink up — the keep warm feature didn't keep the coffee as warm as other models in our tests.
Manual or semi-automatic machines offer more control of shot quality. Because when to cut the shot (brew time) is a critical variable, which is often adjusted shot-by-shot, semi-automatic machines are often preferred over automatics, though some machines are automatic. Manual machines are more popular in Europe, where it is more common to drink straight espresso.
Only two optional settings are available: You can control the heating element under the carafe and turn down the temperature if desired. Other than that, the Moccamaster doesn't have—and doesn't need—anything else. Technivorm boasts that its heating element can get water between 196ºF and 205ºF, which specialists say is the ideal temperature for brewing coffee.
The term dual boiler is used narrowly for machines with two separate boilers, and more broadly for what are more properly called dual heater (DH) machines, featuring a boiler for brewing and a separate thermoblock (TB) for heating brew water to steaming temperature – opposite to HX machines, where the boiler is at steaming temperature and is cooled to brewing temperature.

“For home brewers, the Mr. Coffee 12-cup, programmable machine can produce great morning coffee that’s decent by most standards. Just make sure you use good water — NYC tap is more than acceptable, though filtered is even better. I’d say it’s also even more important to have a grinder that has a nice, even particle size distribution. I have a Baratza Encore on hand, but recently I’ve been relying heavily on the Handground brand grinder, which is a great ergonomic manual.” — Elliott Foos, barista at Café Integral
