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.
The Breville machine was also the only semi-automatic model to produce a velvety, well-incorporated foam. The consistency with which it incorporated air made for a beautifully textured latte—and our coffee expert was even able to make some latte art with it (something that was impossible with the air bubbles from other models, including the Gaggia and all of the less expensive machines).
The Breville's conical burr grinder, made of stainless steel, effortlessly grinds coffee beans and optimizes flavor extraction by maximizing the surface area of the grinds. A 54mm tamper ensures expert tamping control, and a hands-free grinding cradle leaves all the hard work to the machine. Our favorite features are the Breville's grind size/grind amount selector dials, which enable you to customize grinds from fine to coarse.
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.
Finally, the design and extra tools that the Breville machine comes with are impeccable. It includes a large drip tray to catch spilled coffee and milk and has a sensor that lets you know when the tray is too full. It also has a compartment under the drip tray that allows you to store the extra filters the machine comes with. It includes a hefty, stainless steel milk steaming jug and a tamper for pressing the expresso grounds down. Other machines' tampers are made of flimsy plastic that left loose grounds around the sides of the portafilter, but the Breville tamper is made of thick, durable plastic and metal. It's strong enough to actually work well at compacting the grounds, plus it's perfectly sized to fit the entire circumference of the portafilter, reaching all of the grounds and not leaving loose stragglers. There's also a magnetic slot on the machine where you can house the tamper. It can be used while it's attached to the top of the machine, or taken down for more leverage—this is an impressive extra design feature, since the many parts required in making espresso can make for clutter.
The Breville Barista Express comes with everything you need to pull great espresso. A built-in grinder lets you adjust grind coarseness, and changing the amount of ground coffee that you want in your shot is easy: Simply turn a dial or press the portafilter firmly against the dispensing cradle. A button at the back allows you to dose as much or as little coffee as you wish.
This testing was designed to highlight the difference in how each machine extracted its coffee grounds. Remember, extraction is tied to water temperature, how long the grounds had to steep, and how evenly that water is distributed in the brew basket. (Depending on how the machine distributes the water and the shape of the basket, any particular ground may or may not receive the same amount of time in contact with water — thus any individual grind may be over-extracted, under-extracted, or just right.) Properly extracted grounds would have a balance of notes and aromas, from slight hints of acid to a pleasant amount of bitterness.
Our top pick is the OXO On 12-Cup Coffee Brewing System. It’s a large machine – both in footprint and in capacity — but it earned the second-highest scores in our taste test, and is sleek both to look at and to operate. Convenient features like programmable auto-brewing, a removable water reservoir that doubles as a kettle, and a spigot that stops the brew mid-stream if you remove the carafe make this machine feel high tech without being high maintenance. For those who want to be a little more hands-on with the brewing process, its single-button dial also lets you adjust the water’s brewing temperature, giving you more access to experiment with extraction and flavor.
"I have used this machine for about a week, and it is awesome! I had used an espresso machine frequently years ago, but got sick of the grinding, prepping, priming, etc., especially before work in the morning. So, I eventually gave up and bought a plain-ole coffee maker. Unfortunately, "regular" coffee, to me, tastes like hot water. I even tried a Kuerig, but returned it within a month - it was more convenient, but the coffees are no higher quality than any grocery-store brand coffee. So I debated for a long time about whether I should wait for one of these brand-new Nespresso Vertuoline machines, or just buy one of the older, espresso-only Nespresso machines.
The monks thought the goat herder was a fool, and told him as much by throwing the beans in the fire. Sigh. Well, soon the enticing aroma of fresh roasted coffee was too much to ignore. The monks henceforth reversed their snubbing of coffee beans, scooped them out of the fire and threw them into some hot water. Then they drank the dark brew. Ta-da! The first cup of coffee! That was back in the year 850CE.
The Hamilton Beach 12-Cup BrewStation coffee maker offers convenient one-hand dispensing without a conventional glass carafe. There's no pouring or spills, and nothing fragile to break and replace. No matter how much you try, it’s impossible to get freshly brewed flavor from coffee that’s been sitting on a hot plate too long. That’s why the Hamilton Beach BrewStation was created, the only coffeemaker that keeps coffee tasting fresh for up to four hours. This best-selling coffee maker...
The tall tower is fixed on a rectangular base, with a water tank that looks something akin to a trapezoid. The hard plastic funnel allows your favorite paper filters to fit inside of it. It is recommended that you use type 4 paper filters, however. You also have the option to use permanent gold filters if you want to move away from reoccurring costs.
CR’s take: If you’re an aficionado of fresh ground coffee, this Black+Decker is the brewer to buy. As the name suggests, the Mill & Brew goes that extra mile, grinding whole coffee beans just before brewing. As a result, the machine is capable of making a great pot of coffee. Made of plastic with stainless steel accents, this model is easy to use and to clean, earning a Very Good rating in our convenience tests. It allows you to adjust brew strength, and it’s programmable, so you can set it to grind and brew just before you wake up.
