The top espresso machines are simple to use, simple to clean and can create rich and balanced shots. How do you pick the most efficient espresso machine for your home?
This Breville model with its fast-heating thermocoil design and digital ease of use is perfect for anyone who doesn't have the time to learn barista skills but wants great coffee at home.
Pump-driven
Pump-driven machines make use of an electric pump to provide the force needed to make espresso. These machines typically take water from a mains supply, common with commercial installations, or a reservoir that must be filled manually (common with smaller commercial espresso machines). Pumps are typically solenoid piston types, which can produce high pressure. Some espresso machines driven by pumps come with a fixed flow regulator and others allow you to alter the pre-infusion or the brewing pressure.
These are the most popular machines and are perfect for those who want an consistent, high-quality cup of coffee. These machines are simpler to clean and maintain than other types, but they require electricity and a place near an outlet.
They are available in two basic types: semi-automatic and super-automatic. Semi-automatics let you control the length of time that the shot is pulled for by using a manual switch or a programmed function. Additionally, you can adjust the grind setting and to tamp the coffee. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter however, they require constant flow of pressurized liquid.
A vibrating pump starts off very quietly but can eventually sound like a scream if the machine needs to be fed water. Both have pros and cons and you should choose the one that best suits your needs best.
Pump-driven machines are also available in a variety of sizes and price. The most expensive machines are typically super-automatic, and include multiple boilers that separate the water for brewing as well as steaming. These models have heat exchangers that can be set at different temperatures to provide variations in flavor. While this extra functionality makes them a great option for the busy barista at home, it does increase their price. Semi-automatics can be a good middle option. They can be reasonably priced but they don't provide the same quality and flexibility of other alternatives.
Steam-driven
Steam-driven machines utilize an easy system to make an espresso that is powerful. In an airtight container, steam is heated to create pressure, which is transferred to the coffee grounds to make espresso. This is similar to what happens in the stovetop moka kettle and these machines are still popular today due to their low cost and small size. These models aren't capable of achieving the 9 bars of pressure required for true espresso. These models are best for those just starting out with homebrewing, or who don't care about making the perfect espresso.
The earliest example of a steam-driven device is the compensatory siphon balancing machine in 1878 developed by German engineer H. Eicke. small espresso machine Coffeee is produced by this machine, which carries boiling beans through filters. The water is depressurized using heat from an open flame. This makes a robust shot, however it doesn't meet the high standard of consistency that many espresso lovers prefer.
Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. His invention was able lower the temperature of the boiler, which allows for more stable pressure and temperature control. Bezzera also added the piston-based device, which helped to make this machine semi-automatic. The only problem was that it took the barista to grind, measure and tamp the beans manually.
This led to the development of a pump-driven espresso machine. This type of espresso machine, unlike those older steam-driven machines that were heated by an open flame, features an electric pump capable of producing high levels of pressure required to make espresso. The machines can take water directly from an existing cold water line which is common in commercial establishments, or they can use a separate tank that is filled with water by hand.
These machines also have two temperature settings that are controlled by the push of a button. One of these buttons turns on the temperature of the brew while the other switch on the steam temperature. This kind of machine is able to provide consistent shots for less than what it costs when compared to steam-driven models.
Semi-automatic
Semi-automatic machines are the best option for those who want to brew their espresso quickly and easily. It takes away the need for barista training by automating the process of grinding, tamping, and extraction to ensure consistently good results. It doesn't do all the work for you. You still need grind the beans, then tamp them down in the portafilter, and then push the water through.
Many amateur and professional coffee-lovers prefer to use semi-automatic coffee makers because they like 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 espresso machines are often located in shops that are not specialty shops and in the homes of coffee drinkers who want to pay more for convenience. They come with dual boilers to ensure that the steam and brewing water are separated while one is heating up and the other is used to make the beverage you prefer. Some models even come with an integrated grinder, which can be a big 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. It is best to use a semi-automatic espresso machine with an external grinder to have complete control over the size of the grinder.
If you're looking for an espresso machine semiautomatic make sure you choose one with a low-noise, high-quality electric pump, and a PID temperature controller that allows precise temperature regulation. The PID is typically found in high-end toaster and immersion circulators. It assists in stabilizing the brewing system by monitoring temperature fluctuations during the heating cycle.
Furthermore, a high-quality semi-automatic machine should have a powerful enough steam wand that can create microfoam, and also be able to switch between brewing and steaming modes quickly (if it does not have two boilers). A semi-automatic model with all these features can be an excellent option for those who don't want to learn how to make high-quality cafe drinks however nonetheless want to play.
Manual
Manual espresso machines are operated with levers that push pressurized coffee grounds through a bed. This results in highly concentrated shots. These machines are less expensive than semi-automatic or fully automated machines which is why they are popular with coffee drinkers.
Manual espresso machines require more focus and expertise by the operator to maximize their capabilities. Choosing the right grinder, ensuring that the brew ratio is in order, and understanding how to properly dose and make sure your grounds are tamping properly are some of the things you'll need be aware of before using a manual machine.
While some find the learning curve of manual machines challenging and difficult but those with the right knowledge can make it worthwhile effort. Adrian Lini, CHOICE's expert barista, believes that if one has the patience and the right tools, a manual machine can make the best espresso.
In recent years, the hand-operated espresso machine has evolved in both its form and function. It now has more advanced features, like digital pressure gauges, which allow users to monitor pressure during extraction. Charles, who works at Flair Espresso, explains that these machines can also be used by Bluetooth devices to draw graphs of flow rate to help users understand how changing various variables during extraction can impact the overall result.
There are two main types of manual espresso machines: direct and spring piston. Direct levers are equipped with springs in their group heads, which helps boost pressure during brewing. Although they cost more but they are also easier to use than spring-assisted machines.
Springs piston machines, on the other hand, don't have anything in their group heads other than the steam valve. They are easier to use but do not offer the same degree of control over the brewing process. The choice of the best machine is based on your personal preferences and budget. Whichever you choose a manual espresso machine will require a few basic accessories, including kettles, coffee grinder, and a portafilter with the option of removing a dispersion filter made of metal.
