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.
Espresso shots need to be pulled between 186 and 194 degrees F. If the water is too cold when it hits the espresso, the shot tastes sour. Too hot, and it tastes burnt. It’s trickier to hit this window if you also want your machine to steam milk, since steam requires a higher temperature — at least 212 degrees. But we struggled to get several of our machines just to pull decent espresso, never mind the milk. Sour shots were a clear sign that the water wasn’t hot enough; scorched shots indicated that the water climbed over 200 degrees.
A steam-driven unit operates by forcing water through the coffee by using steam or steam pressure. The first espresso machines were steam types, produced when a common boiler was piped to four group heads so that multiple types of coffee could be made at the same time. This design is still used today in lower-cost consumer machines, as it does not need to contain moving parts. Also, steam-driven machines do not produce as high of a pressure for extraction compared to pump-driven. This results in the crema, a hallmark of an espresso, being of lower quality.
Start your morning out right and perk up your day with a freshly brewed pot of coffee! This 12-Cup Retro Series Coffee Maker features an easy-to-read backlit LED display and a push-button control panel which allows for easy programming on the 24-hour clock and delay timer. The 2-hour automatic shut-off is built in for added safety while the pause-and-serve lets you pour a cup of coffee while in the middle of brewing.
“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
“I LOVE my Breville. I am a career barista. I have had this machine for almost a year now and waited to write a review until now so I wasn’t blinded by the initial excitement of purchasing a home espresso machine. I love to buy more expensive coffee from third-wave roasters, and this machine is so easy to dial in, I come away with professional shots almost every time. While this may be due to my experience in the shop, I will say that my husband is not a barista and picked up dialing in pretty fast using the Breville guides [that were] included. My only complaint is that the steaming wand is not the best. It takes a couple tries starting it up to get it going full blast some mornings, but I have always been able to achieve latte art. That is a very small complaint considering this machine is half the price of its competitors but still can create some awesome coffee. I’d highly recommend it for baristas on a budget.”
Breville's 12-cup Precision Brewer is stacked with features that allow you to fully customize your coffee, like adjustable brew temperature, bloom time, strength and more. It also has settings for making cold brew, iced coffee, or the Specialty Coffee Association's standard Golden Cup. It's beautifully designed thanks to its sleek brushed stainless steel exterior and LED-lit digital display. Just note that you'll have to spend time exacting your preferred settings, especially when you first set it up.

“My absolute love of the DeLonghi Magnifica ESAM3300 is hard to describe. It has been a faithful, crema-steeped friend and morning ritual for at least eight years, and the current unit I bought as a replacement last week (another ESAM3300) is a testament to why I give this well-built Italian stallion and ‘super automatic’ espresso dream machine a SOLID five-star rating. With very few adjustments and some good Italian or locally roasted whole beans, the Magnifica consistently puts out shot after shot of delicious espresso that will FAR exceed anything you could get at most coffee shops. I always use many of the yummy Lavazza beans, including the Super Crema, Gold Selection, and others that work really well with this machine. The Illy beans are also a nice pairing for this superb machine. The key is, you want nonoily and fairly dry beans (as other reviewers have said here already).”
In the semi-automatic machine, water pressure and temperature must be stable and consistent, and according to our expert, the pressure shouldn't be too high. Typically, coffee is brewed at a pressure of about 10 bars, and an ideal water temperature is around 195 degrees. Generally, the more expensive the machine, the better the equipment inside that regulates these two factors. High-quality machines tend to have a mechanism called a PID, or proportional-integral-derivative, controller. The PID's function is to maintain constant water temperature with extreme accuracy, down to the degree. Two central problems plaguing inexpensive espresso machines is that they lack a PID, meaning the temperature of the brewing water can fluctuate up and down and yield inconsistent results. Inexpensive machines often advertise that they have 15 or 20 bars of pressure as a selling point. But, higher pressure is not the priority, and too much pressure can actually lead to over-extraction and bitterness in your espresso shot. Therefore, we looked for a machine with good temperature and pressure control.
“I like the Technivorm Moccamaster because, from a scientific standpoint, it creates the proper water temperature (and temperature consistency) for good extraction of flavor from the beans. That’s the problem with most cheap automatics — they’re inconsistent about temperature. It also has a shower-head design for good water dispersion and saturation of the grounds. It consistently tastes almost (almost, I stress) as good as a manual drip.” — Andrew Chou, engineer, General Motors

The gist: The Litchi Portable is similar to the Cisco in that it's very simple to use. Rather than Nespresso pods, use the measuring scooping to add ground coffee to the two-filter basket. Then, add hot water to the chamber and manually push the pressure pump until the coffee comes out. Soon you'll be brewin' the good stuff into the little included cup (even add a little milk if you want to go the cappuccino route.)
The gist: Taking the first spot on our list is the Breville BES870XL. This machine is no joke and its 4.3 star Amazon rating from over 1,800 reviews speaks to that. It boasts a 15 bar Italian pump and a 1600 watt thermo coil heating system. It comes with a 54mm tamper, a stainless steel conical burr grinder, and a 2-liter removable water tank. It's available in three colors: black, red, and silver.
Instead, our main concern was how well the wand incorporated air and steam into the mix for velvety, frothy texture. In our testing with our coffee expert, he pointed out that inferior steamer wands made giant air bubbles that quickly popped and only pumped air into the milk, without incorporating foam consistently throughout. So, we looked for a steamer wand that made consistent, well-incorporated foam.
CR’s take: The Cuisinart Coffee on Demand is a self-serve model. It stores 12 cups of brewed coffee in a reservoir and has a dispenser instead of a carafe. It makes sense in homes where people are drinking coffee at different times; it keeps coffee hot and ready, so family and guests can fill their own cups. This model is programmable and features a water filter and a cleaning indicator. The reservoir can be removed for washing. In our tests, the Coffee on Demand performs quite well, receiving a Very Good rating for convenience. At less than $100, it can be a terrific choice for entertaining.
