A buyer’s guide to espresso machines

The best home espresso machines have an advanced brewing process and handy accessories like double portafilter baskets for double shot drinks and milk frothers for cappuccinos and lattes These automatic machines don’t come cheap and you can expect to pay at least $600 for something that whips up legit cafe-caliber espresso drinks. The machine itself has an amazingly small footprint, and puts out adequate pressure for brewing single/double espresso shots and for properly steaming milk.

The De’Longhi Dedica Deluxe Espresso Machine is a 6″ appliance that lets you choose between 1 or 2 shots of espresso, has a 3-in-1 filter holder that can take single shots, double shots, and easy serve espresso pods which can heat up to ideal brewing temperature with Thermoblock technology. The machine is super easy to use: just choose either a single or double shot, select your coffee grounds, fill the milk and water reservoir and choose your brew.

Moka pots differ from espresso machines in that they brew under substantially lower pressure – 1.5 bars (21 psi) rather than 9 bars (130 psi) – and use hotter water – a mix of boiling water and steam at above 100 °C (212 °F), rather than 92-96 °C (198-205 °F) of espresso machines, similar to early steam brewing machines. Although the water for brewing remains at a lower range than that required for steaming milk, it is still too hot for proper coffee extraction without first cooling; thus this type of machine requires a cooling flush of 4-6 seconds prior to the first espresso pull. Some home pump espresso machines use a single chamber both to heat water to brewing temperature and to boil water for steaming milk.

Notably, the Breville Barista Touch and Bambino also have ThermoJet heaters” that made the machines surprisingly quick to heat and transition between pulling a shot and steaming milk—some drink preparations took barely over a minute from start to finish. Espresso machines are designed and built to perform close-tolerance operations, using highly pressurized hot water/steam, and finely milled, precision-ground coffee beans. Unfortunately, many modern steam-powered espresso machines still have inconsistent pressure, which can result in substandard shots.

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. But ultra-fine grounds proved to be a little problematic on most of the espresso machines we tested anyway, producing slow extractions that resulted in muddy, incomplete shots. The Barista touchscreen is easy to use and displays timers for grinding and brewing, to help you refine your shot.

Owing to its PID control, which helps regulate the water temperature, and Breville’s speedy ThermoJet” heater, it maintains a consistent temperature for multiple shots and requires almost no wait time when switching over to the steam wand after pulling a shot. The Breville Bambino Plus was the easiest to use of all the machines we tested, and its consistent shots and capacity to efficiently steam finely textured milk make it the most powerful, dependable, and fun machine we tested under $900. Super-automatic machines (also called fully automatic) do everything for you: measuring and grinding the beans, pulling the shot, and frothing the milk.

For $600, the machine’s formidable grinder pulverizes espresso beans, smart technology doses grounds directly into its portafilter basket, plus its sturdy frother steams milk well and makes thick foam. During the process, I made and sampled scores of espresso shots, double shots, lattes, cappuccinos and pitchers of steamed milk. The coffee pours out of the machine from the same nozzles as the espresso – except instead of two shots, you get a small cup.

The machine has one element that can provide two different temperatures, one lower temperature for brewing, and a higher one for steaming and providing hot water. Single boiler espresso machines use just one boiler for heating both the water for the espresso shot and the steam wand. The pre-infusion feature allows you to push a small quantity of water into the coffee to kick-off the brewing process, allowing the grounds to degas before full pressure is applied.

Purge and wipe off the steam want following every use, and run a shot of water through your machine after each brewing session. It can use pods or ground coffee in a patented dual function filter holder and features separate thermostats that allow for both water and steam pressure to be controlled for a great cup of espresso every time. Espresso requires pressurized water to be sent through finely-ground coffee beans to create concentrated shots.

What if we told you that there was nothing stopping you from pulling shots and steaming milk just like the baristas at your local coffee stop? Because when to cut the shot (brew time) is a critical variable, which is often adjusted shot-by-shot, semi-automatic machines are often preferred over automatics, though some machines are automatic. These machines automatically grind the coffee, tamp it, and extract the espresso shot.

Machines that have pumps, sensors, valves, and grinders to automate the brewing process are generally referred to as automatic. 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. The term dual boiler is used narrowly for machines with two separate boilers, and more broadly for what are more properly called dual heater (DH) machines, citation needed featuring a boiler for brewing and a separate thermoblock (TB) for heating brew water to steaming temperature – opposite to HX machines, where the boiler is at steaming temperature and is cooled to brewing temperature.

Some machines use a single boiler kept at steaming temperature, but water for brewing is passed through a heat exchanger , taking some heat from the steam without rising to the same temperature. Some baristas pull espresso shots directly into a pre-heated demitasse cup or shot glass, to maintain a higher temperature of the espresso. Alternatively, you can program this via glass touchscreen, along with steam pressure, water temperature (adjustable to the tenth of a degree) and shot timers.

There are no crank start mechanisms or chokes to contend with on manual espresso machines, but because they don’t maintain constant water pressure on their own, users must push water through the coffee manually, which can vary the quality of the final product. It’s super-easy: tap to make espresso, tap to foam milk, tap to change the brew temperature, or choose a pressure profile made for you by competition baristas.
