Pump-driven
Pump-driven machines depend on an electric motor to generate the force needed to make espresso. They typically accept water from the mains supply, as is typical for commercial installations or a reservoir which has to be filled manually (common with household and smaller commercial espresso machines). The pumps used are typically solenoid-piston types that can generate high levels of pressure. Some pump-driven espresso machines come with a fixed flow regulator while others allow you to adjust the pre-infusion and/or brewing pressure.
The most popular type of machine, these are an excellent option for those looking to make high-quality coffee quickly and consistently. They are also simpler to clean and maintain than other types of equipment however, they require some electrical power and a space near an outlet.
They come in two basic varieties: semi-automatic and super-automatic. Semi-automatics let you control the amount of time the shot is pulled by using the manual switch or programmable function. In addition, you are able to adjust 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 however, they require a constant flow pressurized liquid.
A vibrating pump on the other hand, is able to start quite quietly. However, it may sound like a scream when water is added to the machine. Both types have pros and cons and you should pick one that is suitable for your needs.
Pump-driven machines are available in a range of sizes and price ranges. The most expensive machines are typically super-automatic, and include multiple boilers that separate the water for brewing and steaming. They also have heat exchangers that can be set to different temperatures to allow for an array of flavors. This extra functionality is great for busy baristas at home, but it increases their price. The middle option is a semi-automatic which can be very affordable but doesn't offer the same consistency and flexibility as other options.
Steam-driven
Steam-driven machines utilize an easy system to make an intense 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 happens in a Moka stovetop. These machines are still in use today because of their cost-effectiveness and small size. However, these models do not have the ability to produce the 9 bars of pressure required for true espresso. These models are suitable for those just starting out making espresso at home or those who don't worry about making the perfect espresso.
The earliest example of a steam-driven device is the compensatory siphon balancing machine in 1878 created by German engineer H. Eicke. The steam produced by this device pushes boiling water through a filter containing ground beans. It is then depressurized with the help of heat of an open flame spirit burner. This makes a strong shot, but it isn't up to the high standard of consistency that a lot of espresso enthusiasts prefer.
Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. His design allowed him to lower the temperature of the boiler. This allows for a more consistent temperature and pressure control. Bezzera also had the piston-based device, which helped to make this machine semi-automatic. The only issue was that it took the barista a while to grind, measure and tamp the beans by hand.
This led to the development of a pump-driven espresso machine. Contrary to older steam-driven machines, which were heated with an open flame, this type of machine has an electric pump that is capable of generating the high levels of pressure needed for brewing espresso. The machines can take water from a cold line which is a common feature in commercial facilities. Or they can use an additional water tank that has to be filled manually.
They also have two temperature settings that are controlled by a push button. One button activates the brew thermostat while the other switches on the steam thermostat. This kind of machine can produce consistent shots at a fraction of what it costs compared to older steam-driven models.
Semi-automatic
For those who are seeking a simple method to make espresso without a lot of hassle the semi-automatic machine is the answer. It can eliminate barista training by automating the process of grinding, tamping, and extraction to give consistent results. But it doesn't take care of everything for you. You'll still have to grind the beans and then 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 machines because they like the feeling of being more involved in the process of making coffee. These machines also have a lower price tag than their fully-automatic counterparts, and tend to be more reliable too.
These espresso machines are often found in shops that are not specialty and in the homes of coffee drinkers who want to spend more for convenience. They feature dual boilers so that the brewing water and steam are kept separate, while one is heating up while the other is used to make the beverage you prefer. Some have even an integrated grinder, which can be a big time-saver for the user.
The espresso grinder built into the machine is often limited in its settings, which can be frustrating for those who want to customize the process of brewing their own espresso. An alternative is to use a semi-automatic espresso machine with an external grinder to have complete control over the size of the grind and the amount.
If you are interested in a semiautomatic espresso machine be sure to choose one that has a low-noise, high-quality electric pump, and a PID temperature control that allows precise temperature regulation. The PID is typically found in top-quality toasters and immersion circulators. It aids in stabilizing the brewing process by analyzing the temperature fluctuations throughout the heating process.
A decent semi-automatic espresso maker will also have an efficient steam wand to produce microfoam, as well as the capability to switch between steaming and brewing modes quickly (if it does not include dual boilers). With all these options, a top-quality semi-automatic espresso maker can be an excellent choice for those looking to get rid of the hassle and expense of learning how to make high-quality coffee but have fun experimenting with the process.
Manual
Manual espresso machines operate with levers that push pressurized coffee grounds through a bed. This produces highly concentrated shots. These machines are traditionally less expensive than semi-automatic and fully automatic counterparts, which makes them popular for those who appreciate a fine cup of coffee.
Manual espresso machines require more attention and skill from the operator to maximize their capabilities. You'll also have to select the correct grinder and make sure that the brew proportion is right.
While some people may be able to find the process of learning operating a machine manual difficult, for those with the right set of skills, it can be worth the effort. Our expert barista in-house at CHOICE, Adrian Lini, says that if you have the right tools and the determination to learn the basics, a manual espresso maker can provide the ultimate espresso experience.
In machine espresso , espresso machines that are operated by hand have improved in both appearance and function with more advanced 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 create graphs of flow rates which can help users to understand how varying variables during extraction can affect the overall outcome.
There are two types of manual espresso machine: direct and spring-piston. Direct levers have springs inside their group heads that helps to increase the pressure when making espresso. They're more expensive than spring-assisted machines however, they are still easier to use.
Springs piston machines are limited to the steam valve within their group head. They are simpler to use however they do not provide as much control over the making process. The best machine for you will be based on your budget and personal preferences. Whatever you choose, a manually operated espresso machine will require a few essentials such as a portable filter, a coffee mill, and kettle.
