Pump-driven
Pump-driven machines rely on an electric pump for the force required to brew espresso. These machines either accept water directly from the mains, as is typical in commercial installations, or have a reservoir that must be manually filled (common for espresso machines used in homes and smaller commercial espresso machines). Pumps are typically solenoid pistons, which can produce high pressure. Some espresso machines with pump-driven systems have fixed flow rates, while others let you adjust the pre-infusion or brewing pressure.
These are the most popular machines and are perfect for anyone looking for an steady, high-quality cup coffee. These machines are easier to clean and maintain than other types, but they require electricity and a place near an outlet.
There are two basic types: semi-automatics and super-automatics. Semi-automatics allow you to control the amount of time the shot is pulled for with an electronic switch or a programmable function. In addition, you are able to control the grind setting and make sure that the coffee is tamper-proof. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter but they require constant flow of pressurized liquid.
A vibrating pump, on other hand, starts out quite quietly. However, it could sound like a scream when water is added to the machine. Both have pros and cons, and you must pick one that best suits your needs.
Pump-driven machines also come in a range of sizes and price. The most expensive models are usually super-automatic, and come with multiple boilers to separate the water used to steam and brew. These models come with heat exchangers which can be set at various temperatures to allow a variation in the flavor. This extra functionality is great for the busy barista at home, but it can increase their price. Semi-automatics are a great middle option. They can be affordable however they don't have the same consistency and versatility of other alternatives.
Steam-driven
Steam-driven machines use an easy method to create a powerful espresso. In an airtight container, hot water is steamed to create pressure, which is then absorbed into the coffee grounds. This is similar to what happens in a stovetop moka pot and these machines are still used today for their affordability and small size. However, these machines do not have the ability to produce the 9 bars of pressure required for true espresso. This makes them best for those who are just beginning to learn about making espresso at home or aren't concerned with making the perfect espresso.
A very early example of a steam-driven device is the 1878 compensation siphon balancer designed by German engineer H. Eicke. Steam is produced by this machine, which is used to push boiling beans through filters. The water is then depressurized using heat from an open flame. This process produces a very strong shot, but it isn't up to the standard of consistency that many espresso lovers would prefer.
Luigi Bezzera patented improvements in 1901, which led to the next breakthrough. The design of his invention allowed him to lower the temperature of the boiler. This allows for a more constant temperature and pressure control. Bezzera also had a piston-based device that made the machine semi-automatic. The only problem was that it required the barista to grind, measure and tamp the beans manually.
This led to the development of an espresso machine that is driven by a pump. This type of espresso machine, unlike the older steam-driven ones that were heated by an open flame, has an electric pump that is capable producing the high levels of pressure needed for the brewing of espresso. These machines can either accept water directly from the cold water line typical in commercial facilities, or they can use a separate tank that is filled with water manually.
The machines also come with two temperature settings that can be controlled via a push button. One of these buttons switch on the temperature of the brew, while the other one controls the steam temperature. This type of machine can make consistent shots at less than what it costs as compared to steam-driven models.
Semi-automatic
Semi-automatic machines are the ideal choice for those who want to make espresso quickly and efficiently. It takes away the need for 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 need to grind the beans and tamp them in the portafilter prior to the water is forced through them.
Many coffee lovers, both professional and amateur, prefer to use semi-automatic coffee makers for this reason, as they like the feeling of being more involved in the process of making coffee. They also come with an affordable price compared to their fully automated counterparts, and they are also known to be more reliable as well.
These espresso machines are typically located in shops that are not specialty shops and at the homes of casual coffee drinkers who are willing spend more for convenience. They come with dual boilers to ensure that the brewing water and steam are kept separate, while one is heating up and the other is being used to prepare the beverage you prefer. Some models even come with an integrated grinder, which could be a major time-saver for the user.
However the built-in grinder typically has a limited number of settings that can be quite frustrating for those interested in tinkering with the espresso-brewing process to create their own personal favorites. It is best to combine a semi-automatic espresso machine with an external grinding to have complete control over the grind size.
If you're looking to purchase a semi-automatic espresso machine, ensure that you select one with a high-quality electric pump with low-noise, and precise temperature regulation through the PID controller. The PID is typically used in high-end toasters and immersion circulators. It helps stabilize the brewing system by monitoring the temperature fluctuations throughout the heating cycle.
A high-quality semi-automatic espresso machine should also have an efficient steam wand to create microfoam, and the capability to switch between steaming and brewing modes quickly (if it doesn't have dual boilers). With all these features, a quality semi-automatic espresso maker is an ideal choice for those who wish to avoid the hassle and expense of learning how to make cafe-quality drinks but still appreciate some flexibility with the process.
Manual
Manual espresso machines utilize levers to push pressurized water across a bed of finely ground coffee, resulting in extremely concentrated shots. These machines are less expensive than fully automated or semi-automatic machines and are therefore popular with coffee enthusiasts.
Contrary to automated espresso machines, which are designed with user-friendliness in mind, manual espresso makers require more knowledge and attention by the operator to get the most of their potential. Choosing the right grinder, ensuring that the brew ratio is in order and knowing how to properly dose and make sure your grounds are tamping properly are some of the things you'll need to know prior to using a manual machine.
While some find the process of learning manual machines difficult and frustrating but those with the right knowledge are able to make it worth the effort. Our expert barista in-house at CHOICE, Adrian Lini, says that if you have the right tools and the patience to learn the basics, a manual espresso maker can provide the ultimate espresso experience.
In recent years, the hand-operated espresso machine has changed in its form and function. It now includes more sophisticated features, like digital pressure gauges that allow users to monitor the pressure during extraction. Charles who works at Flair Espresso, explains that these machines can also be paired with Bluetooth devices to digitally draw graphs of flow rate, helping users understand how changing different variables during extraction can impact the overall result.
There are two types of manual espresso machine: direct and spring-piston. Direct levers have a spring in their group heads to increase pressure during brewing. They're more expensive than spring-assisted units, but they're still simpler to operate.
Springs piston machines on the other hand, don't have anything in their group heads except the steam valve. They're much easier to use than direct lever machines, but don't offer as much control over the process of brewing. The right machine for you will be based on your budget and personal taste. Whatever you decide to go with, an espresso machine that is manual will require a few necessary equipment, such as kettles, coffee grinder, and a portafilter with an adjustable dispersion screen made of metal.
