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.
You can check out our best milk frothers here. Some of you will stick with the machine's frothing wand, but you'll still need a milk frothing pitcher, so we recommend this one from Rattleware. Should you want a better tamper, we recommend this one from Rattleware. To save money on the coffee grinder, you can try this manual Hario Skerton Ceramic Coffee Mill, but if you want a high-end one, you may pay more than $200 for it.
Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.

"I love this machine! I've been using my Mr. Coffee Cafe Barista for 9 months and it's still going strong. I mainly bought it because I was spending way to much getting coffee drinks like lattes and macchiatos at the coffeehouse. My favorite feature is the fact that it steams and froths the milk at the same time. You can also control the amount of froth that it makes which is an awesome feature. I also have a Mr. Coffee burr grinder Mr. Coffee BVMC-BMH23 Automatic Burr Mill Grinder, Black/Silver so that I am making the freshest coffee possible and I buy my coffee freshly roasted from a local company. The results are great!"
The built-in burr grinder is high quality, and you can easily adjust the grind size and amount with a dial on the front of the machine. You can choose to use either a single- or double-wall filter basket, and the grinder will automatically adjust to give you the right about of coffee grounds for your brew. Reviewers love that it comes with the grinder and praise its quality.
We tested 12 models by making shots of espresso and lattes on each machine. We enlisted the help of an expert from Students of Coffee, a group of coffee educators and roasters at New York University, to judge for quality. The majority of the models we tested were semi-automatic, meaning brewers still have to grind the coffee and pack it in the portafilter (the little filter cup with a wand that you place in the front of the machine). Semi-automatic espresso machines heat the water for you, and then pump it through the grounds at varying levels of pressure, depending on the machine. The semi-automatic models we tester were:
The single-serve or single-cup coffeemaker has gained popularity in recent years. Single-serve brewing systems let a certain amount of water heated at a precise temperature go through a coffee portion pack (or coffee pod), brewing a standardized cup of coffee into a recipient placed under the beverage outlet. A coffee portion pack has an air-tight seal to ensure product freshness. It contains a determined quantity of ground coffee and usually encloses an internal filter paper for optimal brewing results. The single-serve coffeemaker technology often allows the choice of cup size and brew strength, and delivers a cup of brewed coffee rapidly, usually at the touch of a button. Today, a variety of beverages are available for brewing with single-cup machines such as tea, hot chocolate and milk-based specialty beverages. Single-cup coffee machines are designed for both home and commercial use.
It also automatically pre-infuses the coffee, allowing the grounds to vent their CO2 and “bloom.” Remember, only half of the machines we tested had this feature, and it proved to pay off in our taste tests. The four machines we recommend all pre-infuse. Only one coffee maker without it, the Hamilton Beach, performed well at all in our taste tests — but that guy was so cheap and flimsy, part of the brew basket broke during our testing. Sorry, Hamilton Beach.
Hand-tooled and bench-tested in Italy, this espresso maker looks, works, and performs like it belongs in a small coffee shop, despite fitting tidily on your kitchen counter. This machine is built to last 10 to 15 years; less expensive machines at best might survive the five-year mark, and some can’t be expected to reach three. We also loved the sheer quality of every part included with our Rocket. The heft metal tamp fits perfectly in the machine’s own portafilter baskets and improved the shot-making experience of other machines when we used it with theirs.
The Gaggia Classic is a stylish old-school Italian espresso maker. It can pull a really delicious, creamy shot of espresso, but the machine does not have a PID—therefore its results aren't very consistent. While the machine is pretty, it doesn't have the well-thought design features of the Breville, like a sensor drip tray and a space for the tamper, nor does it come with a milk pitcher. Its plastic tamper is flimsy and won't effectively press down the espresso grounds. The Gaggia's steamer wand also doesn't consistently incorporate foam, and instead produces large bubbles on top.
CR’s take: This Cuisinart drip coffee maker with a stainless steel finish and glass carafe earns an Excellent rating for brew performance. It’s programmable and features a water filter, a permanent coffee filter, cleaning mode, a cleaning indicator, and auto-shutoff. The machine also allows you to adjust the strength of your brew. For the money, this model offers style and features that are hard to beat. If you can live without the built-in grinder of the Cuisinart Burr Grind & Brew above, you can save yourself some money and still enjoy Cuisinart quality for a lot less.
