Espresso Machines - Which One is Right For Your Home?

The top espresso machines are easy to use, easy to clean and able to make powerful and balanced shots. How do you pick the  best espresso machine  for your home?

This Breville model is ideal for those who don't want to learn barista skills, but still want great coffee at home.

Pump-driven

Pump-driven machines make use of an electric pump to deliver the force needed to prepare espresso. They either take water directly from the mains, which is common in commercial installations, or contain a reservoir that has to be manually filled (common for household espresso machines and smaller commercial espresso machine). The pumps used are often solenoid-piston models that can produce high levels of pressure. Some espresso machines with pump-driven systems have a fixed flow rate, while others allow you to adjust the pre-infusion pressure or brewing pressure.

The most well-known type of machine, they are a great option for those who want to make high-quality coffee quickly and consistently. These machines are simpler to clean and maintain than other types, but they require electricity and a place near an outlet.

They are available in two basic types: semi-automatic and super-automatic. Semi-automatics let you control the length of time that the shot is pulled by using a manual switch or a programmable function. Additionally, you can adjust the grind setting and to tamp the coffee. Certain semi-automatics feature motors that are rotary as well as others that vibrate. Rotary pumps are quieter and more consistent but require a continuous flow of pressurized water.

In contrast, a vibrating pump begins very quietly but can start to sound like a scream once the machine has to be fed water. Both have pros and cons, and you should choose the one that fits your lifestyle the best.

Pump-driven machines are also available in a variety of sizes and price. The most expensive machines are typically super-automatic, and include multiple boilers that separate the water for brewing and steaming. The heat exchangers in these models can be set to various temperatures, allowing for some variation in the taste of the espresso. This extra functionality is great for busy baristas at home, but it will increase the price. The middle option is a semi-automatic which can be affordable but doesn't offer the same level of consistency and versatility as other alternatives.

Steam-driven

Steam-driven machines use a simple system to produce an espresso that is powerful. Inside an airtight tank hot water is steamed to create pressure which is transferred into the coffee grounds for brewing. This is similar to the process that occurs inside a stovetop moka pot and these machines are still used today for their affordability and small size. However, these models do not have the ability to achieve the 9 bar pressure needed for authentic espresso. This is why they are best for those just getting started with homebrewing or don't have a problem with making the perfect cup of espresso.


One of the earliest examples of a steam-driven machine is the 1878 compensation siphon balancer developed by German engineer H. Eicke. The steam produced by this device pushes boiling water through a filter of ground beans, which is then depressurized with the help of heat of an open flame spirit burner. This process produces a powerful shot, but it doesn't meet the standards of consistency that a lot of espresso enthusiasts prefer.

The next breakthrough came with Luigi Bezzera's 1901 inventions. The design of his invention allowed him to reduce the temperature of the boiler. This allows for a more stable temperature and pressure control. Bezzera included an engine piston to make this machine semi-automatic. The only problem was the barista had to grind, measure, and tamp beans manually.

This led to the creation of a pump-driven espresso machine. This type of espresso machine, in contrast to those older steam-driven machines, which were heated by an open flame, features an electric pump capable of generating high levels of pressure required for brewing the espresso. These machines can accept water from a cold line which is common in commercial installations. Or they can use an individual water tank that has to be filled manually.

These machines also feature two temperature settings that can be controlled via a push button. One of these buttons switch on the brew temperature, while the other one controls the steam temperature. This type of machine is more precise than older steam-driven models and can provide consistent shots at a fraction of the cost of the more expensive models.

Semi-automatic

If you're looking for a method to make espresso with less hassle the semi-automatic machine is the solution. It can eliminate barista training by automatizing the process of grinding, tamping, and extraction to produce consistent results. It does not do all the work for you. You'll still need to grind the beans, then tamp them down in the portafilter, then push the water through.

This is why many amateur and professional coffee drinkers prefer semi-automatic machines, since they feel the satisfaction of being more in control of the process of making coffee. They also come with less cost than their fully automated counterparts, and they are also known to be more reliable as well.

These types of espresso machines are commonly found in coffee shops that are not specialty and at home of casual coffee lovers who are willing to spend more money for convenience. Dual boilers permit the steam and brewing process to be kept separate. One is used for heating, while the other is used to prepare your preferred beverage. Some models come with an integrated grinder which can save the user much time.

However, the built-in grinder often has a limited number of settings which can be a hassle for those who are more inclined to play around with the espresso-brewing process to make their own personal favorite. It is better to use a semi-automatic espresso machine with an external grinding to ensure full control over the grind size.

If you're considering a semi-automatic espresso machine, ensure that you select one with a top-quality electric pump with low-noise, and precise temperature regulation through a PID controller. The PID is usually found in high-end toaster and immersion circulators. It aids in stabilizing the brewing system by monitoring temperature fluctuations during the heating cycle.

A high-quality semi-automatic espresso machine will also have a steam wand powerful enough to produce microfoam, as well as the ability to switch between steaming and brewing modes quickly (if it doesn't include dual boilers). With all of these features, a quality semi-automatic espresso maker is a great option for those who wish to avoid the hassle and expense of learning to make high-quality coffee but appreciate some flexibility with the process.

Manual

Manual espresso machines utilize levers to push pressurized water across a bed of finely ground coffee to produce extremely concentrated shots. They are less expensive than semi-automatic or fully automatic machines, which makes them popular with coffee drinkers.

Manual espresso machines require more attention and skill from the operator to maximize their capabilities. Selecting the right grinder, ensuring that the brew ratio is correct and knowing how to dose and make sure your grounds are tamping properly are some of the things you'll need know before using a manual espresso machine.

While some might find the learning curve operating a machine manual difficult but for those with the right skills, it can be worth the effort. Adrian Lini, CHOICE's expert barista, says that if one has the patience and the right tools manual machines will make the finest espresso.

In recent times, espresso machines operated by hand have seen a rise in both design and function, with more sophisticated features like digital pressure gauges that allow users to track the pressure of extraction. Charles, who works at Flair Espresso, explains that these machines can also be connected with Bluetooth devices to digitally create graphs of flow rates, helping users to understand how varying variables during extraction can affect the overall outcome.

There are two kinds of manual espresso machine which are spring-piston and direct. Direct levers are equipped with a spring in their group heads, which helps increase the pressure when the brewing process. They're more expensive than spring-assisted machines, but can still be easier to use.

Springs piston machines on the other hand, have nothing in their group heads other than the steam valve. They're easier to use than direct lever machines however they don't provide as much control over the process of brewing. Choosing the right type of machine is based on your preferences and your budget. Whichever one you choose, a manual espresso machine will require a few necessary equipment, such as kettles, coffee grinder, and a portafilter with the option of removing a dispersion filter made of metal.
