The top espresso machines are easy to operate, simple to clean, and able to create rich and balanced shots. How do you choose the best espresso machine for your home?
This Breville model is ideal for those who don't wish to learn barista skills but still want to enjoy great coffee at home.
Pump-driven
Pump-driven machines utilize an electric pump to supply the force required for espresso brewing. These machines typically take water from a mains supply, which is common in commercial installations or a reservoir which has to be filled manually (common with household and smaller commercial espresso machines). The pumps that are used are usually solenoid-piston types that can generate high levels of pressure. Certain espresso machines that are driven by pump systems have a fixed flow rate, while others let you adjust the pre-infusion or brewing temperature.
The most well-known type of machine, these are a good option for those looking to make coffee of high quality quickly and consistently. They are also simpler to maintain and clean than other kinds of machines, but do require some electricity and a location near an outlet.
There are two main types: semi-automatics and super-automatics. Semi-automatics let you regulate how long the shot is pulled by using a manual switch or a programable function. You can also adjust the grind setting and tamp down the coffee. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter, however, they require constant flow of pressurized liquid.
In contrast, a vibration pump can start off quiet but it can soon sound like a scream when the machine has to be supplied with water. Both have pros and cons, and you should choose one that best suits your needs.
Pump-driven machines are also available in a range of sizes and prices. The most expensive models are usually super-automatic and feature multiple boilers that separate the water used for steaming and brewing. The heat exchangers of these models can be set to different temperatures, allowing for some variation in the flavor of the espresso. This extra functionality is great for the busy barista working at home, but it will increase the price. Semi-automatics are a good middle ground. They can be reasonably priced but they don't provide the same quality and flexibility of other options.
Steam-driven
A steam-driven machine employs an easy mechanism to make a strong espresso. In an airtight container, hot water is heated to create pressure which is then transferred to the coffee grounds. This is similar to the process that takes place in a stovetop Moka pot. These machines are still in use today because of their cost-effectiveness and compactness. These models aren't able to reach the 9 bar pressure needed to make a true espresso. These models are suitable for those who are just beginning making espresso at home, or who don't care about making the perfect espresso.
A very early example of a steam-driven machine is the 1878 compensation siphon balancing machine created by German engineer H. Eicke. Steam is produced by this machine, which is used to push boiling beans through an aerator. The water is then depressurized with heat from an open flame. This makes a strong shot, but it does not meet the standard of consistency that many coffee lovers like.
The next step forward was Luigi Bezzera's 1901 inventions. The design of his invention allowed him to lower the temperature of the boiler. This allows for a more consistent temperature and pressure control. Bezzera also added an engine-driven device that helped to make this machine semi-automatic. The only problem was that it took the barista to grind, measure and tamp the beans by hand.
This led to the creation of a pump-driven espresso machine. Contrary to older steam-driven machines, which were heated with an open flame, the new kind of machine has an electric pump that is capable of producing the high pressure required to make espresso. These machines can be able to take water from a cold line which is typical in commercial facilities. Or they can use an additional water tank that must be filled manually.
The machines also come with two temperature settings that are controlled by a button. One of these buttons switch on the temperature of the brew while the other switch on the steam temperature. This kind of machine can produce consistent shots at a fraction of what it costs as compared to steam-driven models.
Semi-automatic
If you're looking for an easy method of making espresso with less effort, the semi-automatic machine is the solution. It can eliminate barista training by automatizing the process of grinding, tamping, and extraction to give consistent results. However, it doesn't take care of everything for you. You'll have to grind the beans and tamp them in the portafilter before the water is being pushed through them.
This is why many coffee lovers prefer a semi-automatic machine, as they enjoy the feeling of being more in control during the brewing process. These machines also have less cost than their fully-automated counterparts, and they tend to be more reliable too.
These espresso machines are typically found in non-specialty coffee shops and at home of casual coffee drinkers who are willing to pay more for convenience. Dual boilers allow steam and brewing to remain 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 users much time.
The espresso grinder that comes with the machine is usually limited in its settings, which can frustrate those who want to modify the process of making their own espresso. It is recommended to combine a semi-automatic espresso machine with an external grind to have full control over the grind size.
If you're looking for a semiautomatic espresso machine be sure to choose one that has a low-noise, high-quality electric pump, and a PID temperature control that can provide precise temperature control. The PID is a piece of technology that's usually used in immersion circulators and high-end toaster ovens and helps stabilize a brewing boiler by analyzing the temperature fluctuations during the heating cycle.
A decent semi-automatic espresso maker must also come with a steam wand powerful enough to produce microfoam, as well as the ability to switch between brewing and steaming modes quickly (if it does not include dual boilers). A semi-automatic machine with all of these features could be an excellent option for those who don't wish to learn how to make drinks that are cafe-quality however still want to play around.
Manual
Manual espresso machines operate with levers that push coffee grounds pressurized through the bed. This results in highly concentrated shots. They are cheaper than fully automated or semi-automatic machines and are therefore popular with coffee drinkers.
Unlike automated espresso machines, which are designed with user-friendliness in mind, manual espresso makers require more expertise and focus by the operator to get the most of their potential. Choosing the right grinder, making sure that the brew ratio is correct, and understanding how to properly dose and tamp your grounds are just some of the things you'll need know before using a manual machine.
While some people may find the learning curve operating a machine manual frustrating, for those who have the right capabilities, it's well worth the effort. CHOICE's in-house expert barista, Adrian Lini, says that if you have the right tools and the patience to learn, a manual espresso maker can give you the best espresso experience.
In recent years, hand-operated espresso machines have grown in both form and function with more sophisticated features such as digital pressure gauges that let users monitor the pressure while extracting. Charles, who is employed by Flair Espresso, says that the machines can be paired with Bluetooth devices to digitally plot graphs for flow rate. This helps users understand how changing variables in extraction can affect the final outcome.
There are two types of manual espresso machine : direct and spring-piston. Direct levers have springs inside their group heads, which helps to increase the pressure when brewing. They're more expensive than spring-assisted units, but they're still simpler to operate.
Springs piston machines have only the steam valve in their group head. They're easier to use than direct lever machines however they do not provide as much control over the process of brewing. The ideal machine for you will depend on your budget and personal taste. Whatever you choose, a manually operated espresso machine will require a few essentials such as an able filter as well as a coffee mill and a kettle.
