Espresso Machines - Which One is Right For Your Home?
The top espresso machines are simple to use, simple to clean and can make powerful and balanced shots. But how do you know which one is the right one for your home?
This Breville model, with its quick-heating thermocoil design, and digital convenience is perfect for anyone who doesn't have the time to learn barista skills, but would like to enjoy excellent coffee at home.
Pump-driven
Pump-driven machines use an electric pump to provide the force required for espresso brewing. They either take water directly from the mains, which is typical in commercial installations, or they have a reservoir that must be manually filled (common for home espresso machines and smaller commercial espresso machine). Pumps are usually solenoid piston types, which can generate high 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.
These are the most popular machines, and are perfect for anyone who wants a consistent, high-quality cup of coffee. They can also be easier to maintain and clean than other kinds of machines, but do require a certain amount of electrical power and a space near an outlet.
They come in two basic kinds: semi-automatic as well as super-automatic. Semi-automatics let you control the length of time that the shot is pulled for with a manual switch or a programable function. You can also adjust the grind setting, and tamp down the coffee. Some semi-automatics are equipped with motors that rotate as well as others that vibrate. Rotary pumps are quieter and more reliable but require a continuous flow of pressurized water.
In contrast, a vibrating pump starts off very quietly but can start to sound like a scream when the machine has to be supplied with water. Both types have their pros and cons, and you should choose the one that best suits your needs best.
Pump-driven machines are available in a variety of sizes and price ranges. The most expensive models are usually super-automatic, and come with multiple boilers that separate the water used for steaming and brewing. These models have heat exchangers that can be set to different temperatures to allow for a variation in the flavor. This is a great feature for the busy barista at home, but it will increase the price. The middle ground is a semi-automatic, which is a great value but doesn't provide the same consistency and flexibility as other alternatives.
Steam-driven
Steam-driven machines employ a simple system to produce an intense espresso. In an airtight container, hot water is steamed to create pressure, which is then transferred into the coffee grounds. This is similar to the process used in a stovetop Moka pot. These machines are being used today due to their low cost and their compactness. machines espresso machines are not capable of reaching the 9 bar pressure needed for true espresso. This is why they are best for those just getting started with homebrewing or don't have a problem about making the perfect espresso.
The 1878 compensation siphon balancer developed by German engineer H. Eicke is a early steam-driven machine. Steam is produced by this machine, which carries boiling beans through an aerator. The water is then depressurized using heat from an open flame. This process produces a powerful shot, but it doesn't meet the high standards of consistency that many espresso drinkers prefer.
Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. His invention allowed him to lower the temperature of the boiler. This enables more stable temperature and pressure control. Bezzera also included a piston-based device that helped to make this machine semi-automatic. The only issue was that it took the barista a while to grind, measure and tamp the beans by hand.
This led to the development of an espresso machine that is driven by a pump. In contrast to the steam-driven machines of the past that were heated by an open flame, this new type of machine uses an electric pump capable of generating the high pressure needed for brewing espresso. These machines can be able to take water from a cold line, which is typical in commercial facilities. They can also use a separate water tank that has to be filled manually.
The machines also come with two temperature settings that are controlled by a push button. One of these buttons switches on the brew temperature, while the other switch on the steam temperature. This type of machine can make consistent shots at a fraction of what it costs when compared to steam-driven models.
Semi-automatic
If you're seeking a simple method of making espresso with less effort, the semi-automatic machine is the solution. It eliminates barista training by automating the process of grinding, tamping, and extraction to produce consistently good results. It does not complete all the work for you. You still have grind the beans, then tamp them down in the portafilter, then push the water through.
Many coffee lovers, both professional and amateur, prefer to use semi-automatic coffee makers for this reason, as they enjoy being more involved in the brewing process. They also come with a lower price tag than their fully-automatic counterparts, and tend to be more reliable, too.
These espresso machines are typically found in coffee shops that are not specialty and in the homes of casual coffee drinkers who are willing to spend more money to enjoy convenience. They come with dual boilers to ensure that the brewing water and steam are separated while one is heating up and the other is used to create the beverage you prefer. Some have even a built-in grinder that could be a major time-saver for the user.
However the built-in grinder usually has a limited number of settings, which can be frustrating for those interested in tinkering with the process of brewing espresso to create their own personal favorites. It is best to combine a semi-automatic espresso machine with an external grinding to have total control over the grind size.
If you are interested in a semiautomatic espresso machine make sure you choose one with a low-noise, high-quality electric pump, and a PID temperature control that permits precise temperature control. PID controllers are typically found in high-end toaster and immersion circulators. It assists in stabilizing the brewing process by analyzing variations in temperature during the heating process.
A decent semi-automatic espresso maker should also have a steam wand that is powerful enough to produce microfoam, as well as the capability to switch between brewing and steaming modes quickly (if it does not have two boilers). With all of these features, a quality semi-automatic espresso maker could be a great option for those looking to save the time and money of learning to make cafe-quality drinks but still have fun experimenting with the process.
Manual
Manual espresso machines utilize levers to push pressurized water through a bed of finely ground coffee to produce extremely concentrated shots. They are typically less expensive than semi-automatic and fully automatic counterparts, making them popular among discerning coffee lovers.
Contrary to automated espresso machines, designed with ease of use in mind manual espresso makers require more expertise and focus from the operator to make the most of their potential. You'll also need to choose the correct grinder and ensure that the brew percentage is correct.
While some people find the learning curve of the manual espresso machine to be challenging and difficult but those with the right skills can make it worthwhile effort. Adrian Lini, CHOICE's expert barista says that if one has the patience and the right tools, a manual machine can produce the best espresso.
In recent years, the hand-operated coffee machine has evolved in both its appearance and function. It now comes with more advanced features, such as digital pressure gauges, which allow users to monitor pressure during extraction. Charles, who works at Flair Espresso, explains that these machines can also be connected with bluetooth devices to digitally create graphs of flow rates to help users understand how changing various variables during extraction can affect the final outcome.
There are two types of manual espresso machines: direct and spring-piston. Direct levers are equipped with springs in their group heads to help increase the pressure when making. They're more expensive than spring-assisted machines however, they are still easier to operate.
Springs piston machines On the other hand, have nothing in their group heads, aside from the steam valve. They are more user-friendly but don't offer the same degree of control over the brewing process. The ideal machine for you will be based on your budget and personal preferences. Whatever you decide on a manual espresso machine will require a few basic components such as the ability to carry a filter around as well as a coffee mill and a kettle.
