Espresso Machines - Which One is Right For Your Home?
The best espresso machines are easy to use, simple to clean and can create well-balanced and rich shots. But how do you decide which one is the right one for your home?
This Breville model, with its quick-heating thermocoil design and digital ease of use is perfect for a person who doesn't have the time to learn barista skills, but would like to enjoy good coffee at home.
Pump-driven
Pump-driven machines depend on an electric motor to generate the force needed to make espresso. They typically accept water from a mains supply, which is common in commercial installations, or a reservoir that is filled manually (common with household and smaller commercial espresso machines). The pumps used are often solenoid-piston designs that can create high pressure. Some pump-driven espresso machines have a fixed flow control and others allow you to alter the pre-infusion or brewing pressure.
The most popular kind of machine, these are a good option for those who want to make high-quality coffee quickly and consistently. They are simpler to maintain and clean than other models, however they require electricity and space near an outlet.
They are available in two fundamental kinds: semi-automatic as well as super-automatic. Semi-automatics let you regulate the amount of time the shot is pulled with the manual switch or programmed function. You can also adjust the grind setting, and tamp down the coffee. Some semi-automatics are equipped with motors that are rotary and others are vibrating. Rotary pumps are quieter but they require constant flow of pressurized liquid.
In contrast, a vibrating pump starts off very quietly but it can soon sound like a scream once the machine has to be fed with water. 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 ones are usually super-automatic and feature multiple boilers that separate the water used for steaming and brewing. The heat exchangers in these models can be set to different temperatures, which allows for some variation in the flavor of the espresso. This extra feature makes them a great option for the busy barista at home however, it will raise the cost. Semi-automatics can be a good middle option. 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 method to create a powerful espresso. In an airtight container, hot water is steamed to create pressure that is then transferred into the coffee grounds. This is similar to what happens inside a stovetop moka pot and they are popular today due to their low cost and compact size. However, these models do not have the ability to reach 9 bars of pressure needed for a authentic espresso. This is why they are best for those who are just getting started with making espresso at home or aren't concerned with making the perfect cup of espresso.
A very early example of a steam-driven machine is the 1878 compensation siphon balancing machine designed by German engineer H. Eicke. Steam is produced by this machine, which is used to push boiling beans through filters. The water is depressurized using heat from an open flame. This process produces a powerful shot but does not meet the standards of consistency that a lot of espresso drinkers like.
Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. His design allowed him to lower the temperature of the boiler. This allows for a more consistent temperature and pressure control. Bezzera also included the piston device to make this machine semi-automatic. The only issue was that it took the barista a while to grind, measure and tamp the beans manually.
This led to the creation of a pump-driven espresso machine. This brand new espresso machine, unlike the steam-driven models of the past that were heated by an open flame, is equipped with an electric pump that is capable of generating high levels of pressure needed for brewing the espresso. The machines can take water directly from an existing cold water line common in commercial installations or use a separate tank filled with water by hand.
The machines also come with two temperature settings, which are controlled by the push of a button. One button activates the brew thermostat, and the other switch on the steam thermostat. This type of machine is more accurate than older steam-driven models and can produce consistent shots for a fraction of the cost of the more expensive models.
Semi-automatic
For those who are looking for an easy way to brew espresso without a lot of hassle The semi-automatic machine could be the answer. It takes away the need for barista training by automating the process of grinding, tamping, and extraction to produce consistent results. However, it doesn't do everything for you. You'll still need to grind the beans and then tamp them in the portafilter prior to the water is forced through them.
Many coffee lovers, both professional and amateur, prefer semi-automatic coffee makers because they enjoy being more involved in the brewing process. They are also less costly than fully-automatic counterparts 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 are willing spend more for convenience. Dual boilers allow steam and brewing to be kept separate. One is used for heating while the other is used to prepare your preferred beverage. Some have even a built-in grinder, which can be a huge 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 espresso-brewing process to make their own personal preferences. It is better to combine a semi-automatic espresso machine with an external grind to have complete control over the grind size.
If you're considering a semi-automatic espresso machine, ensure you choose one with a top-quality, low-noise electric pump and precision temperature regulation via the PID controller. The PID is usually used in high-end toasters and immersion circulators. It helps stabilize the brewing process by analyzing the temperature fluctuations throughout the heating cycle.
Additionally, a quality semi-automatic machine must be equipped with a strong enough steam wand that can create microfoam, and also be capable of switching between steaming and brewing modes quickly (if it doesn't include dual boilers). A semi-automatic model with all of these features is an ideal choice for those who don't want to learn how to make high-quality cafe drinks, but nonetheless want to play.
Manual
Manual espresso machines use levers to push pressurized water over a bed of finely ground coffee, producing extremely concentrated shots. These machines are traditionally less expensive than their semi-automatic and fully automatic counterparts, which makes them popular for those who appreciate a fine cup of coffee.
Unlike automated espresso machines, designed with ease of use in mind, manual espresso makers require more skill and focus from the operator in order to make the most of their potential. You'll also have to select the correct grinder and make sure that the brew proportion is right.
While Coffeee might find the learning curve involved operating a machine manual frustrating however, for those with the right capabilities, it's worth the effort. Our expert barista in-house at CHOICE, Adrian Lini, says that if you have the right equipment and ability to learn the basics, a manual espresso maker can give you the best espresso experience.
In recent times, espresso machines operated by hand have improved in both appearance and function, with more sophisticated features like digital pressure gauges that allow users to monitor the pressure during extraction. Charles who is employed by Flair Espresso, says that these machines can be used using Bluetooth devices to create graphs of flow rates. This allows users to understand how changing variables in extraction can impact the final result.
There are two types of manual espresso machines that are direct and spring-piston. Direct levers have a spring inside their group heads which help to increase the pressure when making espresso. They're more expensive than spring-assisted machines but they're still simpler to operate.
Springs piston machines, on the other hand, have nothing in their group heads except the steam valve. They're easier to use than direct lever machines but don't provide as much control over the process of brewing. The right machine for you will depend on your budget and personal preferences. Whatever you decide to go with an espresso machine that is manual will require a few basic accessories, such as kettles, a coffee grinder and a portafilter equipped with the option of removing a dispersion filter made of metal.
