Pump-driven machines make use of an electric pump to supply the force required for espresso brewing. They typically accept water from the mains supply, which is common in commercial installations or a reservoir that must be filled manually (common with smaller and household commercial espresso machines). The pumps that are used are usually solenoid-piston models that can produce high levels of pressure. Some espresso machines driven by pumps come with a fixed flow regulator and others allow you to alter the pre-infusion or brewing pressure.
The most popular kind of machine, these are a good choice for anyone who wants to make coffee of high quality quickly and consistently. They are also easier to clean and maintain than other types of equipment however they do require some electricity and a location 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 either a manual switch, or a programmable feature. In addition, you can control the grind setting and to tamp the coffee. Some semi-automatics are equipped with rotary motors as well as others that vibrate. Rotary pumps are quieter, but they require a constant flow of pressurized liquid.
A vibrating pump on the contrary, begins very quietly. However, it can sound like a scream once water is added to the machine. Both have pros and cons, and you should select the one that best suits your lifestyle the best.
Pump-driven machines are available in a range of sizes and price ranges. The most expensive machines are usually super-automatic, and include multiple boilers that separate the water for brewing as well as steaming. These models have heat exchangers which can be set at different temperatures to allow for variations in flavor. This additional feature makes them a good choice for the busy home barista however, it will raise the cost. Semi-automatics can be a good middle ground. They aren't expensive but they don't provide the same level of consistency and versatility of other alternatives.
Steam-driven
Steam-driven machines employ an easy mechanism to make an espresso that is strong. Within an airtight tank, hot water is steamed to create pressure which is transferred into the coffee grounds for brewing. This is similar to the process that takes place inside a stovetop Moka pot. These machines are being used today due to their affordability and compactness. However, these models do not have the ability to reach 9 bars of pressure needed for true espresso. These models are best for those who are just beginning making espresso at home, or who don't care about making the perfect espresso.
The earliest example of a steam-driven machine is the 1878 compensation siphon balancing machine created by German engineer H. Eicke. The steam produced by this device is pushed through a filter of ground beans. It is then depressurized with the help of heat of an open flame spirit burner. This technique produces a robust shot but does not meet the standards of consistency that many espresso drinkers like.
Luigi Bezzera patented improvements in 1901, which led to the next breakthrough. His invention was able lower the temperature of the boiler, which allows for more constant pressure and temperature control. Bezzera also added an engine-driven device that helped to make this machine semi-automatic. The only problem was the barista needed to grind and measure beans manually.
This led to the development of a pump driven espresso machine. Contrary to older steam-driven machines that were heated by an open flame, the new kind of machine is equipped with an electric pump capable of producing the high pressure required to make espresso. These machines can accept water directly from the cold water line common in commercial installations or use a separate tank that is filled with water manually.
They also have two temperature settings controlled by a push button. One button activates the brew thermostat while the other switches on the steam thermostat. This type of machine is more precise than older steam-driven machines, and can provide consistent shots at a fraction of the cost of the more expensive models.
Semi-automatic
Semi-automatic machines are the best option for those who want to brew their espresso quickly and easily. It eliminates barista training by automating the process of grinding, tamping and extraction to ensure consistently good results. However, it doesn't complete the entire process for you: You still must grind the beans and then tamp them in the portafilter before the water is forced through them.
Many amateur and professional coffee-lovers prefer to use a semi-automatic machine because they enjoy the feeling of being more involved in the process of making coffee. They are also less costly than fully-automatic counterparts and tend to be more reliable.
These espresso machines are commonly located in non-specialty coffee shops and in the homes of coffee enthusiasts who are willing to spend more money to enjoy convenience. Dual boilers permit the steam and brewing process to be kept separate. One is used for heating, while the other is used to prepare your preferred beverage. Some models include an integrated grinder which can save users much time.
However the built-in grinder usually has a limited selection of settings which can be a hassle for those who are more than interested in playing around with the espresso-brewing process to create their own personal favorite. An alternative is to combine a semi-automatic espresso maker with an external grinder to get full control over the size of the grind and the amount.
If you're interested in a semi-automatic espresso machine, make sure to look for one with a top-quality electric pump with low-noise, and precise temperature regulation through a PID controller. The PID controller is an element of technology that's typically used in immersion circulators and high-end toaster ovens. It helps stabilize a brewing kettle by analyzing the temperature fluctuations during the heating process.
In addition, a good semi-automatic machine should have a powerful enough steam wand to create microfoam, and also be able to switch between brewing and steaming modes quickly (if it doesn't include dual boilers). A semi-automatic model with all of these features could be an excellent option for those who don't wish to learn how to make high-quality cafe drinks however, they still want to play around.
Manual
Manual espresso machines employ levers to push pressurized water across a bed of finely ground coffee, resulting in highly concentrated shots. These machines are traditionally less expensive than their semi-automatic and fully automatic counterparts, making them popular for those who appreciate a fine cup of coffee.
Unlike automated espresso machines, which are designed with user-friendliness in mind manual espresso makers require more skill 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 understanding how to properly dose and tamp your grounds are just some of the things you'll need to be aware of before using a manual machine.
While some find the process of learning a manual machine difficult and frustrating for those who have the right knowledge can make it worthwhile effort. Our expert barista in-house at CHOICE, Adrian Lini, says that if you've got the right tools and the patience to learn, a manual espresso maker can provide the ultimate espresso experience.
In recent years, the hand-operated coffee machine has evolved in both its appearance and function. It now includes more advanced features, including digital pressure gauges that allow users to monitor pressure during extraction. Charles, who is employed by Flair Espresso, says that these machines can be used with Bluetooth devices to digitally plot graphs for flow rate. This aids users in understanding how changing variables during extraction can affect the final result.
There are two major kinds of manual espresso machines: 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 in their group head. They are simpler to use however they do not provide as much control over the brewing process. The best type of machine is dependent on personal preference and your budget. Whatever you decide to go with an espresso machine that is manual will need a few essential accessories, including kettles, coffee grinder, and a portafilter with the option of removing a dispersion filter made of metal.
