A grouphead (or group head) is the receiver for the removable portafilter (or group handle). A typical consumer espresso machine normally has only one grouphead, while popular professional machines, such as those used at commercial coffee shops, can contain anywhere from one to seven. During the process of extracting a shot of espresso, hot water is forced through the grouphead under pressure. The grouphead contains many holes (the shower) that attempt to distribute the pressurised water evenly over the surface of the grinds in the portafilter basket and thereby achieve an even cross sectional flow.[3]
An electric drip coffee maker can also be referred to as a dripolator. It normally works by admitting water from a cold water reservoir into a flexible hose in the base of the reservoir leading directly to a thin metal tube or heating chamber (usually, of aluminum), where a heating element surrounding the metal tube heats the water. The heated water moves through the machine using the thermosiphon principle. Thermally-induced pressure and the siphoning effect move the heated water through an insulated rubber or vinyl riser hose, into a spray head, and onto the ground coffee, which is contained in a brew basket mounted below the spray head. The coffee passes through a filter and drips down into the carafe. A one-way valve in the tubing prevents water from siphoning back into the reservoir. A thermostat attached to the heating element turns off the heating element as needed to prevent overheating the water in the metal tube (overheating would produce only steam in the supply hose), then turns back on when the water cools below a certain threshold. For a standard 10-12 cup drip coffeemaker, using a more powerful thermostatically-controlled heating element (in terms of wattage produced), can heat increased amounts of water more quickly using larger heating chambers, generally producing higher average water temperatures at the spray head over the entire brewing cycle. This process can be further improved by changing the aluminum construction of most heating chambers to a metal with superior heat transfer qualities, such as copper.
Why it's great: The Magnifica is the lazy espresso aficionado's dream device. It's basically the same thing as having your local coffee shop barista make your drink for you, only you don't have to leave your house or worry about them spelling your name wrong on your cup. Since it's a super-automatic, it pretty much takes care of everything, from tamping, to grinding, to extracting. The only thing you really have to do is fill the containers and push a few buttons. There are so many great features on this thing, with the reheat function being a customer favorite. And the fact that it's able to remember your favorite drink settings? *Chef's kiss.*
Why it's great: With the exception of a few exterior differences, getting the Inissia is basically like getting the Pixie at a discounted price. Aside from the quality espresso, it comes with all the same Nespresso perks: The Nespresso welcome kit has 14 unique capsules and access to the Nespresso club. Through the Nespresso Club you can order capsules either online or by phone, as well as get personalized advice and technical support for your machine 24/7. Not too shabby for a tiny little machine of its price. For those who don't mind being a little less fancy with the exterior design, the Inissia is definitely a great option.

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 actually didn’t start drinking coffee on a regular, daily basis until four or five years ago. I got hooked on the smoothness and low acidity of cold-brewed coffee, and for the longest time, my ritual each morning was to visit Gimme! near my house on Lorimer. Recently, though, I’ve started making cold brew myself at home with the OXO Good Grips Cold Brew Coffee Maker. It’s not a true drip-coffee machine, but I’ve been very happy with this piece of equipment — it lets me tinker with different beans and concentrations, and produces enough cold brew to last me two weeks at a time. It also stacks compactly for storage, which is an absolute requirement for my tiny New York apartment.” — Dennis Ngo, caterer at Lonestar Empire
The Rocket’s espresso lever is an upgrade from the simple on/off button used by most of our models. By only moving the lever part way up, you can play around with pre-infusing your coffee grounds before pulling the shot. Pre-infusion can be fun to tinker with as you try to home in on what makes your perfect espresso. This gives the Rocket an additional level of customization not available on the other models we tested.

For all the debate over whether the best coffee comes from a Chemex or a French press or an AeroPress (even Nespresso), sometimes you just want to turn on a machine and let it do the work. We asked ten coffee drinkers — food-industry professionals and just plain coffee snobs — what’s the coffee machine that’ll get you a simple at-home brew without all the fuss?


“I grind the beans in a Hario hand grinder gifted from my brother to me when he upgraded to a fancy electric one. Using the hand grinder is meditative. It feels like you’re ‘earning’ your morning coffee a little bit more. At home, I use a Muji porcelain pour-over, but when I’m at my family’s house in metro Detroit, I love using their Bonavita BV1800SS. Unfortunately, I don’t have one of my own, but seriously, you can’t fuck it up. Super-easy and delicious every single time.” — Kimberly Chou, co-director of Food Book Fair
With the introduction of the electric drip coffee maker for the home in the early 1970s, the popularity of percolators plummeted, and so did the market for the self-contained ground coffee filters. In 1976, General Foods discontinued the manufacture of Max Pax, and by the end of the decade, even generic ground coffee filter rings were no longer available on U.S. supermarket shelves.
The gist: This machine is clearly a fan favorite, as it’s raked in over 2,400 reviews on Amazon, giving it an average of 4 out of 5 stars — with over 60% of users awarding it a perfect 5 star rating. The machine comes with a lot of bragging rights. Not only is it “Amazon’s Choice” for super-automatic espresso machines, it’s also their #1 best seller.

CR’s take: If you need only one or two cups of coffee each morning and you don’t want a pod coffee maker, consider the Technivorm Moccamaster Cup-One Brewer. Compact and clean-lined, it has a profile that makes some sense of its high price (it retails for more than $200), and it’s a superstar when it comes to reliability. Technivorm was one of only three drip machine brands to earn an Excellent rating for predicted reliability in our member survey. Our testers also give this machine a strong score for brew performance. This model has only one simple feature (auto-shutoff) and it’s not the easiest machine to use, but you can count on it to last.
For hundreds of years, making a cup of coffee was a simple process. Roasted and ground coffee beans were placed in a pot or pan, to which hot water was added, followed by attachment of a lid to commence the infusion process. Pots were designed specifically for brewing coffee, all with the purpose of trying to trap the coffee grounds before the coffee is poured. Typical designs feature a pot with a flat expanded bottom to catch sinking grounds and a sharp pour spout that traps the floating grinds. Other designs feature a wide bulge in the middle of the pot to catch grounds when coffee is poured.

The OXO is SCAA-certified, so we knew going in that it would heat water to the right temperature range and let coffee brew for the right amount of time. But what really sold us on the OXO was how its scrolling dial made even that customizable. Assuming you want to bring the extraction down a touch for lighter, subtler coffee, you can lower the water temperature with a twist of the dial. Likewise, if you want a slightly more robust aroma from your brew, you can increase the water’s temp the same way.
Most people who have this in their homes are happy with it thanks to how easy it is to use and how delicious the coffee comes out. One person said they didn’t know how they managed without it. Some people did have issues with it breaking sooner than they would have liked, but they majority of those who own it were satisfied with the quality of the product.
“Strength, blend, decaf, cream, or sugar, there are many options when it comes to a cup of coffee. It seems every person has his or her own unique preferences to get them that perfect cup of joe. However, one factor that was often out of the home-coffee fan’s control was temperature. You either drank it at the temperature it came out of the coffee maker or you let it cool somewhat before sipping began. Cuisinart has aimed to turn that limitation on its head. This Cuisinart DCC-3650 adds a temperature control. It actually brews the coffee at one of three different user-defined temperatures. Impressive.”

A cafetiere (Coffee Plunger, French press in US English) requires coffee of a coarser grind than does a drip brew coffee filter, as finer grounds will seep through the press filter and into the coffee.[2] Coffee is brewed by placing the coffee and water together, stirring it and leaving to brew for a few minutes, then pressing the plunger to trap the coffee grounds at the bottom of the beaker.
Although it's very easy to use — you just fill the portafilter with grounds, attach it to the machine, and press the button to start — The Gaggia Classic isn't as flexible or intuitive as the Breville Barista Express. The user manual is less detailed, too, so you have to have a basic idea of what you're doing or browse the internet for tips. The machine has a one-year warranty if you run into problems.
Some home pump espresso machines use a single chamber both to heat water to brewing temperature and to boil water for steaming milk. However, they can perform only one operation at a time, requiring a warm up period between the execution of espresso pull and the milk frothing process. Since the temperature for brewing is less than the temperature for creating steam the machine requires time to make the transition from one mode to the other. Moreover, after the brewing process, a single boiler will expel (usually minor) quantities of water through the steam wand that were left over from brewing, which can cause the steam heated milk to then have a slightly watered down taste. To avoid this, the leftover water needs to be collected from the steam wand before steaming of the milk should begin. SB/DUs are generally found within the lower tiers of enthusiast home models, with steam wands being a simple and valued addition.
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.

"Honestly, i bought this for my wife as a novelty item. I saw it on a lightning deal, she loves espresso, it looked cool, figured why not? Well, what was supposed to be just something for a little fun (which was, when she has used it) ended up being something she really likes and is planning on taking to work on a regular basis (she says it makes great espresso and is a quick and easy way to do it). Plus, she said it will be great when we go camping (no electric or batteries required, just hot water and it's easy to clean). it arrived quickly and in perfect condition. So, I guess I 'done good' ;)"

Before we get into the technical aspects of the two types of espresso machines, here’s what you really need to know. Semi-automatic espresso machines are going to be perfect for the espresso connoisseur. If you’re the type that really wants to get the best-quality and taste out of your espresso machine and don’t mind taking a little more time and effort out of your schedule, the semi-automatic espresso maker is going to be for you. It’s a little bit more work, but the key here is that you ultimately have more control over every subtle nuance that goes into your version of the perfect shot of espresso with a semi-automatic.

"Oh my goodness! I never knew such a thing existed. This tiny espresso maker makes great espressos! I have taken this to work with me and everyone is jealous. I mean everyone is jealous for real. I think I even persuaded some of my colleagues to buy one themselves! How funny is that? It's so easy to use. I usually use hot water to begin with and I don't bother with getting it to heat my water for me because that just takes a little bit too long. Holding the button for more than 5 seconds will activate the pressurized pumping gear. It is all electronic so you don't have to make any difficult pumping like in some other smaller products. The coffee comes out just as good as any espresso you can make. And the pods are crazy cheap. I found pods that are literally $0.10 each."

Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about coffee machines, coffee grinders, even gifts for coffee lovers, here, we’ve gone deep on the best espresso machines on Amazon, according to the people. (Note that reviews have been edited for length and clarity.)
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).
Hamilton Beach 49980A is made for occasional drinkers and caffeine aficionados alike, with the system fixed with all of the latest programs while still being relatively affordable.
