Pump-driven machines utilize an electric pump to provide the necessary force to prepare espresso. These machines typically either accept water from a mains supply, as is typical for commercial installations or a reservoir that must be filled manually (common with household and smaller commercial espresso machines). Pumps are usually solenoid piston types, which can produce high pressure. Some espresso machines with pump-driven systems have a fixed flow rate while others let you adjust the pre-infusion pressure or brewing pressure.
The most well-known type of machine, they are a great option for those looking to make coffee of high quality quickly and consistently. They are simpler to maintain and clean than other models, however they require electricity and a place near an outlet.
They come in two basic kinds: semi-automatic as well as super-automatic. Semi-automatics let you control how long the shot is pulled through the manual switch or programmed function. You can also alter the grind setting, and then tamp down the coffee. Some semi-automatics have motors that are rotary and others are vibrating. Rotary pumps are quieter and more consistent however they require a constant flow of pressurized water.
A vibrating pump, on contrary, begins quite quietly. However, it can sound like a scream when water is added to the machine. Both have pros and cons, and you should choose one that is suitable for your needs.
Pump-driven machines are available in a variety of sizes and price ranges. The most expensive models are typically super-automatic and have multiple boilers to separate the water used for steaming and brewing. The heat exchangers on these machines can be set to various temperatures, which allows for some variation in the flavor of the espresso. This extra functionality is great for busy baristas at home, but it can increase the cost of their products. The middle option is a semi-automatic which can be very affordable but doesn't offer the same consistency and flexibility as other alternatives.
Steam-driven
Steam-driven machines employ an easy mechanism to make an espresso that is strong. Within an airtight tank, steam is heated to create pressure which is then transferred to the coffee grounds to make espresso. This is similar to the process that occurs inside the stovetop moka kettle and these machines are used today for their affordability and small size. These models aren't able to reach the 9 bars of pressure required to make a true espresso. These models are ideal for those who are just beginning with homebrewing or those who don't worry about making the perfect espresso.
The balancer for compensation in 1878 designed by German engineer H. Eicke is a very early steam-driven device. Steam is produced by this machine, which is used to push boiling beans through a filter. The water is then depressurized using heat from an open flame. This makes a powerful shot, however it does not meet the standard of consistency that many espresso lovers would prefer.
Luigi Bezzera patented improvements in 1901 which led to the next breakthrough. His design was able to lower the temperature of the boiler, which allows for more consistent pressure and temperature control. Bezzera included an engine piston to make the machine semi-automatic. The only problem was that it required the barista time to grind, measure and tamp the beans manually.
This led to the development of a pump-driven espresso machine. Unlike the older steam-driven machines that were heated with an open flame, this new type of machine is equipped with an electric pump capable of producing the high levels of pressure required for the brewing of espresso. The machines can take water directly from an existing cold water line common in commercial installations, or they can use a separate tank filled with water manually.
They also have two temperature settings, which are controlled by one button. One of these buttons switches 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 make consistent shots for a fraction of the cost of more expensive models.
Semi-automatic
For those who are looking for an easy way to brew espresso with less effort, the semi-automatic machine is the answer. It removes the need for barista-level education by automatizing the grinding tamping and extraction process to produce consistently good results. However, it doesn't do everything for you: You still need to grind the beans and tamp them in the portafilter prior to the water is pushed through them.
This is the reason why many coffee drinkers choose a semi-automatic machine, as they enjoy the feeling of being more in control during the brewing process. They also come with an affordable price compared to their fully-automatic counterparts, and tend to be more reliable too.
These types of espresso machines are usually found in non-specialty coffee shops and in homes of coffee enthusiasts who are willing to spend more money for convenience. Dual boilers permit the steam and brewing to remain separate. One is used for heating, while the other is used to prepare your preferred beverage. Some models even come with a built-in grinder that can be a big time-saver for the user.
However the built-in grinder typically has a limited number of settings which can be a hassle for those who are more inclined to play around with the process of brewing espresso to create their own personal favorite. It is better to use a semi-automatic espresso machine with an external grind to have complete control over the size of the grinder.
If you're interested in a semiautomatic espresso machine make sure you choose one with an extremely quiet electric pump and a PID temperature controller that can provide precise temperature control. The PID is usually found in top-quality toasters and immersion circulators. It aids in stabilizing a brewing system by measuring the temperature fluctuations throughout the heating cycle.
In addition, a good semi-automatic machine should have a sufficient steam wand to produce microfoam. It should also be capable of switching between steaming and brewing modes quickly (if it does not have two boilers). With all these features, a high-quality semi-automatic espresso maker could be an ideal choice for those who want to save the time and money of learning how to make cafe-quality drinks but still appreciate some flexibility with the process.
Manual
Manual espresso machines are operated by levers that push coffee grounds pressurized through the bed. This results in extremely concentrated shots. These machines are less expensive than semi-automatic or fully automatic machines, which makes them popular with coffee enthusiasts.
Manual espresso machines require more focus and experience by the operator to maximize 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 know prior to using a manual machine.
While some might be able to find the process of learning in operating a manual machine frustrating, for those who have the right skills, it can be worthwhile. CHOICE's in-house expert barista, Adrian Lini, says that if you have the right equipment and ability to learn how to operate a manual espresso machine, it can give you the best espresso experience.
In recent years, the hand-operated coffee machine has changed in its appearance 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 paired with bluetooth devices to digitally create graphs of flow rates to help users understand how changing various variables during extraction can impact the final outcome.
There are two types of manual espresso machine which are spring-piston and direct. Direct levers have a spring in their group heads to increase the pressure when brewing. Although they cost more and more difficult to use than spring-assisted machines.
Springs piston machines on the contrary, have nothing in their group heads except the steam valve. They are easier to use but do not offer as much control over the making process. The right machine for you will depend on your budget and personal preferences. Whatever you decide to go with a manual espresso machine will require a few key components such as the ability to carry a filter around as well as a coffee mill and kettle.
