Pump-driven
Pump-driven machines make use of an electric pump to supply the force required for espresso brewing. They either take water directly from the mains, which is typical in commercial installations, or have a reservoir that must be manually filled (common for household espresso machines and smaller commercial espresso machines). The pumps that are used are usually solenoid-piston models that can produce high pressure. Certain espresso machines that are driven by pump systems have a fixed flow rate, while others allow you to adjust the pre-infusion pressure or brewing pressure.
These are the most sought-after machines and are perfect for anyone looking for a consistent, high-quality cup of coffee. They are also easier to maintain and clean than other types of equipment however they do require an amount of electrical power and a space near an outlet.
They come in two basic varieties: semi-automatic and super-automatic. Semi-automatics allow you to control the amount of time the shot is pulled by using the manual switch or programmable function. You can also control the grind setting, and tamp down the coffee. Certain semi-automatics feature rotary motors, while others vibrate. Rotary pumps are quieter, however they require constant flow of pressurized liquid.
A vibrating pump on the contrary, begins with a quiet start. However, it can sound like a scream when water is added to the machine. Both have pros and cons and you must pick one that is suitable for your needs.
Pump-driven machines come in a variety of sizes and price ranges. The most expensive models are usually super-automatic, and come with multiple boilers to separate the water used for steaming and brewing. The heat exchangers in these models can be set to different temperatures, which can result in some variation in the taste of the espresso. While this extra functionality makes them an ideal choice for busy baristas at home however, it can increase the cost. Semi-automatics are a good middle option. They aren't expensive, but they don't offer the same level of consistency and versatility of other alternatives.
Steam-driven
Steam-driven machines use an easy method to create an espresso that is powerful. Inside an airtight tank steam is heated to create pressure, which is then transferred to the coffee grounds for brewing. This is similar to what happens inside the stovetop moka kettle and they are being used for their value and small size. However, these machines don't have the capacity to produce the 9 bars of pressure needed for true espresso. This makes them best for those just beginning to learn about homebrewing or don't have a problem about making the perfect espresso.
The 1878 compensation siphon balancer designed by German engineer H. Eicke is a very early steam-driven machine. Steam is produced by this machine, which pushes boiling beans through a filter. The water is then depressurized using heat from an open flame. This technique produces a robust shot, but it doesn't meet the high standards of consistency that a lot of espresso enthusiasts prefer.
The next breakthrough came with Luigi Bezzera's 1901 inventions. The design was able to lower the temperature of the boiler, which allowed for more stable pressure and temperature control. Bezzera also included a piston device to help make this machine semi-automatic. The only problem was the barista had to grind, measure, and tamp beans manually.
This led to the development of the pump-driven espresso machine. This new type of espresso machine, unlike those older steam-driven machines, which were heated by an open flame, is equipped with an electric pump capable producing the high pressure levels required for brewing the espresso. These machines can 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.
These machines also feature two temperature settings that can be controlled by a button. One of these buttons turns on the temperature of the brew, while the other switch on the steam temperature. This type of machine is more accurate than older steam-driven models and can produce consistent shots for a fraction of the cost of more expensive models.
Semi-automatic
For those who are seeking a simple method of making espresso without a lot of hassle, the semi-automatic machine is the solution. It takes away the need for barista training by automating the process of grinding, tamping, and extraction to produce consistent results. It doesn't do all the work for you. You'll still need to grind the beans, tamp them down in the portafilter and then push the water through.
Many coffee lovers, both professional and amateur prefer a semi-automatic machine because they like the feeling of being more involved in the process of making coffee. They also come with a lower price tag than their fully automated counterparts, and tend to be more reliable, as well.
These types of espresso machines are commonly located in non-specialty coffee shops and in homes of casual coffee drinkers who are willing to pay more money for convenience. Dual boilers permit the steam and brewing to be kept separate. One is used to heat while the other is used to prepare your favorite beverage. Some models even come with a built-in grinder, which could be a major time-saver for the user.
The espresso grinder that comes with the machine is often limited in its settings, which can frustrate those who want to modify the process of making their own espresso. The best solution is to combine a semi-automatic espresso maker with an external grinder to have full control over the size of the grinder and the amount.
If you're looking to purchase an espresso machine that is semi-automatic, ensure you choose one with a top-quality, low-noise electric pump and precise temperature regulation through the PID controller. The PID is a piece of technology that's typically used in immersion circulators as well as high-end toaster ovens. It helps stabilize a brewing boiler by measuring the temperature variations throughout the heating process.
A decent semi-automatic espresso maker should also have a steam wand that is powerful enough to make microfoam and the capability to switch between steaming and brewing modes quickly (if it doesn't have dual boilers). A semi-automatic model with all of these features is an excellent choice for those who don't want to learn how to make cafe-quality drinks however, they still want to have fun.
Manual
Manual espresso machines are operated with levers that push coffee grounds pressurized through a bed. This results in extremely concentrated shots. They are cheaper than fully automated or semi-automatic machines, which makes them popular with coffee enthusiasts.
Manual espresso machines require greater attention and expertise from the operator to maximize their potential. Selecting the right grinder, ensuring that the brew ratio is right, and understanding how to properly dose and tap your grounds are some of the things you'll need to know before using a manual machine.
Although some people find the process of learning the manual espresso machine to be frustrating and difficult for those who have the right knowledge can make it worthwhile effort. The expert barista at CHOICE, Adrian Lini, says that if you have the right equipment and patience to learn the basics, a manual espresso maker will give you the best espresso experience.
In recent years, the hand-operated espresso machine has evolved in both its form and function. It now has more sophisticated features, such as digital pressure gauges that allow users to monitor pressure during extraction. Charles, who is employed at Flair Espresso, explains that these machines can also be used with Bluetooth devices to digitally create graphs of flow rates, helping users understand how changing different variables during extraction can impact the overall result.
There are two types of manual espresso machines which are spring-piston and direct. Direct levers feature a spring inside their group heads which help increase pressure while making coffee. They're more expensive than spring-assisted units, but can still be easier to use.
Springs piston machines only have the steam valve inside their group head. They are easier to use however they do not provide as much control of the making process. The ideal machine for you will be based on your budget and personal preferences. Whatever you decide to go with a manual-operated espresso machine will require a few essentials that include an able filter, a coffee mill, and kettle.
