Espresso Machines - Which One is Right For Your Home?
The top espresso machines are easy to operate, simple to clean and can make powerful and balanced shots. How do you choose the best espresso machine for your home?
This Breville model is ideal for those who don't want to learn barista techniques, but still want to enjoy great coffee at home.
Pump-driven
Pump-driven machines make use of an electric pump to deliver the force required to make espresso. These machines typically take water from a mains supply, as is typical for commercial installations or a reservoir that is filled manually (common with smaller commercial espresso machines). Pumps are typically solenoid pistons, which can produce high pressure. Some espresso machines with pump-driven systems have a fixed flow rate, while others allow you to alter the pre-infusion pressure or brewing pressure.
These are the most popular machines and are perfect for anyone who wants a consistently high-quality, consistent cup of coffee. They are simpler to clean and maintain than other models, however they require electricity and a space near an outlet.
They are available in two basic varieties: semi-automatic and super-automatic. Semi-automatics allow you to control the amount of time the shot is pulled using either a manual switch, or a feature that can be programmed. You can also alter the grind setting and tamp down the coffee. Some semi-automatics have motors that rotate as well as others that vibrate. Rotary pumps are quieter and more consistent but require a constant stream of pressurized water.
In contrast, a vibration pump begins very quietly but can eventually sound like a scream when the machine is fed with water. Both have pros and cons and you should pick one that best suits your needs.
Pump-driven machines are available in a range of sizes and price ranges. The most expensive ones are usually super-automatic and feature multiple boilers that separate the water used to steam and brew. These models have heat exchangers that can be set at different temperatures to provide variations in flavor. This feature is ideal for the busy barista working at home, but it increases the cost of their products. Semi-automatics are a great middle place. They can be affordable, but they don't offer 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, hot water is heated in order to create pressure which is then transferred into the coffee grounds. This is similar to what happens in a stovetop moka pot and they are popular today due to their low cost and small size. However, these models don't have the capacity to reach 9 bars of pressure needed for a authentic espresso. These models are ideal for those just starting out with home brewing, 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 developed by German engineer H. Eicke. The steam produced by this device is pushed through a filter containing ground beans, which are then depressurized by the heat from an open flame spirit burner. This method produces a strong shot, but doesn't meet the standards of consistency that many espresso enthusiasts prefer.
Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. His invention was able lower the temperature of the boiler, which allowed for more consistent pressure and temperature control. Bezzera also included an engine-driven device that helped make the machine semi-automatic. The only problem was the barista needed to grind, measure, and tamp beans manually.
This led to the creation of a pump-driven espresso machine. Contrary to older steam-driven machines that were heated by an open flame, this new type of machine has an electric pump capable of producing the high pressure needed for brewing espresso. These machines can accept water from a cold line which is a common feature in commercial installations. best coffee espresso machine have the option of using a separate water tank that must be filled manually.
These machines also have two temperature settings that can be controlled by one button. One button activates the brew thermostat, while the other switches on the steam thermostat. This kind of machine is more precise than older steam-driven machines, and can make consistent shots for a fraction of the cost of the more expensive models.
Semi-automatic
Semi-automatic machines are a great option for those looking to make espresso quickly and efficiently. It takes away the need for barista training by automating the process of grinding, tamping and extraction to ensure consistent results. It doesn't do all the work for you. You still have grind the beans, then tamp them down in the portafilter and then push the water through.
This is why many professional and amateur coffee drinkers choose a semi-automatic machine, as they enjoy the feeling of having more control of the process of making coffee. They are also less costly than fully automated counterparts and are generally more reliable.
These types of espresso machines are usually found in coffee shops that are not specialty and at home of casual coffee lovers who are willing to pay more money for convenience. They have dual boilers, which means that the brewing water and steam are kept separate, while one is heating up and the other is being used to make your drink of choice. Some have even a built-in grinder, which can be a huge time saver for the user.
The espresso grinder that comes with the machine is often restricted in its settings, which can be a problem for those who want to modify the process of brewing their own espresso. It is recommended to pair a semi automatic espresso machine with an external grind for complete control over the size of the grind.
If you're interested in a semiautomatic espresso machine make sure you choose one with an extremely quiet electric pump and a PID temperature control that allows precise temperature regulation. The PID is typically found in top-quality toasters and immersion circulators. It aids in stabilizing the brewing process by analyzing temperature fluctuations during the heating process.
In addition, a good semi-automatic machine should have a sufficient steam wand that can create microfoam. It should also be capable of switching between steaming and brewing modes quickly (if it doesn't have two boilers). With all these features, a quality semi-automatic espresso maker is a great option for those who want to get rid of the hassle and expense of learning how to make high-quality coffee but enjoy some degree of tinkering with the process.
Manual
Manual espresso machines are operated by levers which push the coffee grounds through the bed. This produces highly concentrated shots. They are less expensive than fully automated or semi-automatic machines and are therefore popular with coffee lovers.
Manual espresso machines require more attention and skill from the operator to maximize their capabilities. Making the right choice in a grinder, ensuring that the brew ratio is correct, and understanding how to dose and tap your grounds are some of the things you'll need to know before making use of a manual machine.
Although some may be able to find the process of learning in operating a manual machine difficult however, for those who have the right skills, it can be well worth the effort. CHOICE's in-house expert barista, Adrian Lini, says that if you've got the right equipment and ability to learn how to operate a manual espresso machine, it can provide the ultimate espresso experience.
In recent years, the hand-operated espresso machine has changed in its appearance and function. It now has more sophisticated features, like digital pressure gauges, which allow users to monitor the pressure during extraction. Charles who works for Flair Espresso, says that these machines can be connected with Bluetooth devices to plot graphs for flow rate. This allows users to understand how the changing variables during extraction can affect the final result.
There are two types of manual espresso machines that are direct and spring piston. Direct levers have a spring in their group heads, which helps increase pressure during brewing. Although they are more expensive but they are also easier to use than spring-assisted machines.
Springs piston machines are limited to the steam valve within their group head. They're easier to use than direct lever machines however they don't offer as much control over the brewing process. The ideal machine for you will be based on your budget and personal preferences. Whatever you decide to go with, a manually operated espresso machine will require a few key components that include the ability to carry a filter around, a coffee mill, and kettle.
