Espresso Machines - Which One is Right For Your Home?
The most effective espresso machines will be simple to use, clean and provide balanced shots. But how do you decide which one is the right machine for your home?
This Breville model with its rapid-heating thermocoil design, and digital convenience is ideal for someone who doesn't wish to learn barista skills, but would like to enjoy good coffee at home.
Pump-driven
Pump-driven machines depend on an electric motor for the force required to brew espresso. They can either draw water directly from the mains, which is typical in commercial installations, or they have a reservoir which must be manually filled (common for espresso machines used in homes and smaller commercial espresso machine). The pumps used are typically solenoid-piston designs that can create high levels of pressure. Some espresso machines driven by pumps have a fixed flow control and others allow you to adjust the pre-infusion and/or the brewing pressure.
The most popular kind of machine, these are a great option for those who want to make high-quality coffee quickly and consistently. They are also simpler to maintain and clean than other types of machines however, they require a certain amount of electricity and a location near an outlet.
There are two basic types of semi-automatics and super-automatics. Semi-automatics allow you to control how long the shot is pulled for with an electronic switch or a programable function. In addition, you are able to adjust the grind setting and to tamp the coffee. Certain semi-automatics feature motors that are rotary and others are vibrating. Rotary pumps are quieter and more consistent however they require a constant flow of pressurized water.
In contrast, a vibrating pump starts off very quietly but can eventually sound like a scream once the machine needs to be fed water. Both have pros and cons, and you should pick the one that best suits your lifestyle the best.
Pump-driven machines also come in a variety of sizes and costs. The most expensive ones are usually super-automatic, and come with multiple boilers to separate the water used for steaming and brewing. These models have heat exchangers that can be set to different temperatures to allow for an array of flavors. This additional feature makes them a great option for the busy barista at home, it does raise the cost. The middle option is a semi-automatic which can be very affordable but does not offer the same level of consistency and versatility as other alternatives.
Steam-driven
A steam-driven machine employs an easy mechanism to make an espresso that is strong. In a sealed airtight container hot water is heated to create pressure, which is then absorbed into the coffee grounds. This is similar to what happens in the stovetop moka kettle and they are being used for their value and small size. These machines aren't able to reach the 9 bars of pressure required to make a true espresso. This makes them best for those who are just beginning to learn about homebrewing or don't have a problem with making the perfect espresso.
The earliest example of a steam-driven machine is the compensatory siphon balancing machine in 1878 developed by German engineer H. Eicke. The steam produced by this device pushes boiling water through a filter containing ground beans, which are 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 a lot of espresso enthusiasts prefer.
The next advancement came with Luigi Bezzera's 1901 patent improvements. His invention was able lower the temperature of the boiler, which allowed for more consistent 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 had to grind, measure, and tamp beans manually.
This led to the creation of a pump-driven espresso machine. This new type of espresso machine, as opposed to the older steam-driven ones, which were heated by an open flame, features an electric pump that is capable producing the high levels of pressure required for the brewing of espresso. The machines can take water directly from the cold water line which is common in commercial establishments or they can utilize an additional tank that is filled with water by hand.
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 switch on the steam temperature. This type of machine is more precise than older steam-driven models and can produce consistent shots for only a fraction of the price of more expensive models.
Semi-automatic
Semi-automatic machines are the best option for those who want to make espresso quickly and easily. It eliminates the need for barista-level education by automatizing the grinding tamping and extraction process to produce consistent results. It does not do all the work for you. You'll still need grind the beans, tamp them down in the portafilter and then push the water through.
stovetop espresso maker and professional coffee-lovers prefer semi-automatic coffee makers for this reason, as they enjoy the feeling of being more involved in the brewing process. They are also less expensive than their fully-automatic equivalents and tend to be more reliable.
These types of espresso machines are usually found in non-specialty coffee shops and in the homes of coffee enthusiasts who are willing to spend more money to enjoy convenience. They come with dual boilers to ensure that the steam and brewing water are separated while one is heating while the other is used to create the beverage you prefer. Some even have a built-in grinder that can be a big time-saver for the user.
The espresso grinder that comes with the machine is often restricted in its settings, which can frustrate those who wish to alter the process of brewing their own espresso. The best solution is to pair a semi-automatic espresso machine with an external grinder for complete control over the size of the grind and dosage.
If you're interested in an espresso machine semiautomatic, look for one with the lowest noise, a high-quality electric pump, and a temperature controller that allows precise temperature regulation. The PID is a piece of technology usually found in immersion circulators and high-end toaster ovens. It helps stabilize a brewing kettle by analyzing the temperature fluctuations during the heating process.
Additionally, a quality semi-automatic machine must have a sufficient steam wand to create microfoam and be able to switch between steaming and brewing modes quickly (if it does not include dual boilers). With all these features, a high-quality semi-automatic espresso maker can be an excellent choice for those looking to save the time and money of learning to make cafe-quality drinks but still enjoy some degree of tinkering with the process.
Manual
Manual espresso machines employ levers to push pressurized water through a bed of finely ground coffee, producing extremely concentrated shots. They are less expensive than fully automated or semi-automatic machines and are therefore popular with coffee enthusiasts.
Unlike automated espresso machines, that are designed with ease-of-use in mind manual espresso makers require more knowledge and attention from the operator in order to make the most of their potential. You'll also need to choose the correct grinder and ensure that the brew percentage is right.
While some find the process of learning a manual machine frustrating and difficult but those with the right knowledge can make it worth the effort. Adrian Lini, CHOICE's expert barista, says that if you have the patience and the right equipment manual machines can make the best espresso.
In recent years, espresso machines that are operated by hand have grown in both form and function with more sophisticated features such as digital pressure gauges that let users monitor the pressure during extraction. Charles, who works for Flair Espresso, says that these machines can be used with Bluetooth devices to plot graphs for flow rate. This helps users understand how changing variables in extraction can impact the final outcome.
There are two main types of manual espresso machines: direct and spring piston. Direct levers include springs inside their group heads which help to increase the pressure when making espresso. They're more expensive than spring-assisted machines, but can still be easier to operate.
Springs piston machines On the contrary, have nothing in their group heads other than the steam valve. They are more user-friendly but do not offer the same degree of control over the brewing process. The ideal machine for you will depend on your budget and your personal preferences. Whatever you decide to go with a manual espresso machine will require a few essentials that include a portable filter as well as a coffee mill and kettle.
