A portafilter (or group handle) attaches to the grouphead of semi-automatic and piston-driven espresso machines, and carries a tamped puck of coffee grounds within its basket. It is usually made of brass for better heat retention, and is attached by a plastic or wooden handle. The portafilter forms a seal with the espresso machine's gasket, and directs high-pressure hot water through the coffee puck. After-market retailers also sell bottomless portafilters that minimize the espresso's contact with any metal. A bottomless portafilter is one tool baristas use to analyze the quality of the coffee grind and the evenness of the extraction and allows for a visual check of "channeling" or the condition in which water is able to pierce a hole in the espresso puck during the brew process leading to poor extraction. Often, baristas use knockboxes to store their spent espresso grounds after they have pulled a shot.

Once you start brewing, it makes a really, really good pot of coffee. Our taste test revealed the OXO On 12-Cup coffee was “dark and strong” and appealed to the more traditionalist coffee palates. The great flavor comes from the brewing process. The OXO machines have wide shower heads with multiple ports through which water streams, dispersing it evenly throughout the brew basket. Lots of other coffee makers spout water through just one hole, or through shower heads with a smaller radius, which can increase the chances of uneven extraction.
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.
“To me, a great drip-coffee machine is a reliable one with a timer (which is an awesome feature for large families). The Cuisinart DCC-3200 might not be the first choice of snobby coffee experts, but to me it does the trick. It’s cheap and works just fine (it’s actually the one I use myself at home). I love that I can program the timer and wake up to the smell of fresh coffee. Also, friends and family think you’re the best host when they stay with you (even though you’re still sleeping).” — Guillaume Guevara, founder of Miscelanea NY
Why it's great: Flair *really* stresses how important espresso as an "art form" really is. The Flair is for someone who genuinely enjoys the process of creating espresso. It's unique design makes it appealing on the counter or wherever you decide to take it, since it disassembles and folds up nicely into a carrying case. Since it doesn't require electricity, you can take this fancy piece of hardware anywhere. The only downside is that you have to buy your own burr grinder for the best results, but chances are this won't be an issue for someone who is already gung-ho about "the process."

CR’s take: Though this Bialetti lacks typical drip-machine features such as programming and brew-strength control, it more than compensates with a Very Good rating in our brew performance test and a crisp 8-minute brew time. If you’re the type who sometimes prefers a morning shot of espresso to a cup of joe, this twofer—drip machine beside espresso maker—may be for you. It features a built-in milk frother, a permanent coffee filter, and auto-shutoff. CR does not yet have enough survey data on Bialetti machines to rate them on reliability and satisfaction, but when we do, we’ll add that info to our ratings.
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.
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.
While clever baristas are always coming up with twists on common coffee staples, the most popular beverages are based on a shot or more of espresso and steamed milk with a layer of foam artistically placed on top. Cappuccino is among the most popular espresso-based drinks, but with some clever applications of milk and cream, they sky is the limit as to what you can create.
Moka pots, also known as stove top espresso makers, are similar to espresso machines in that they brew under pressure and the resulting brew shares some similarities, but in other respects differ. As such, their characterization as "espresso" machines is at times contentious, but due to their use of pressure and steam for brewing, comparable to all espresso prior to the 1948 Gaggia, they are accepted within broader uses of the term, but distinguished from standard modern espresso machines.
Picking up a bag of coffee beans from the roaster is a great way to make sure you have fresh beans. Because coffee gets damaged as it’s exposed to air, espresso connoisseurs recommend using beans within two weeks of their roast date. But you won’t want to use them the same day that they’ve been roasted — they need a few days to de-gas from the roasting process.
While we love the all-inclusive features of the Breville, there’s one thing it can’t do on its own, at least not without a hefty repair bill. If you love dark roasts, any machine that features an internal grinder is off-limits. The oily shine characteristic of dark roasts builds up in any grinder — but while you can disassemble and clean standalone grinders, this is rarely an option for internal ones. The residual oil left in an internal grinder will, at best, give future shots a rancid flavor. At worst, the oil will clog the grinder. If you want to brew dark roasts on the Breville, plan on buying a separate grinder.
This K-Elite Single-Serve K-Cup Pod Coffee Maker blend premium finish and programmable features together to deliver both modern design and the ultimate in beverage customization. It’s a stylish addition to any kitchen. Features strong brew setting when you want to brew a bolder cup of coffee, and an ice setting to brew hot over ice for a refreshing, full-flavored ice coffee.

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.


For example, if your coffee tastes a bit salty or sour, the grounds are under-extracted, which can be remedied by a finer grind. But what if only some of your grounds are too coarse, and others are too fine – and maybe some are just right? Having uniform grind size throughout your brew basket makes it easier to isolate and adjust this variable in order to get the level of extraction you want. The only way to achieve that is with a burr grinder. Miller — as well as a handful of our other experts — recommends the Barazata Encore Coffee Grinder ($129).
CR’s take: If you like the look of black stainless steel, you can add a hit of the trendy finish to your kitchen with the Bella Ultimate Elite Collection coffee maker. Appearance aside, this model brews a fresh pot in just 9 minutes and is graceful in action, earning strong ratings in our carafe handling tests. It offers programming, brew-strength control, a pause-and-serve feature, and auto-shutoff. Bella drip machines also received a Very Good rating for predicted reliability. At about $50, this affordable, attractive option won’t disappoint.
