Espresso Machines - Which One is Right For Your Home?
The top espresso machines are easy to operate, simple to clean, and able to create rich and balanced shots. But how do you know which one is the best machine for your home?
This Breville model with its fast-heating thermocoil design and digital ease of use is ideal for someone who doesn't have the time to learn barista skills but still wants to make great coffee at home.
Pump-driven
Pump-driven machines use an electric pump to supply the force needed to make espresso. These machines typically take water from the mains supply, as is typical for commercial installations or a reservoir that must be filled manually (common with smaller and household commercial espresso machines). The pumps that are used are usually solenoid-piston types that can generate high levels of pressure. Some espresso machines driven by pumps have a fixed flow regulation while others allow you to adjust the pre-infusion and/or the brewing pressure.
The most popular type of machine, they are a good choice for anyone who wants to make coffee of high quality quickly and consistently. These machines are simpler to clean and maintain than other models, however they do require electrical power and a space near an outlet.
There are two basic types that are semi-automatics as well as super-automatics. Semi-automatics allow you to control the length of time that the shot is pulled for with an electronic switch or a programmed function. In addition, you can control the grind setting and make sure that the coffee is tamper-proof. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter and more reliable but require a continuous flow of pressurized water.
In contrast, a vibration pump can start off quiet but it can soon sound like a scream when the machine has to be supplied with water. Both have advantages and disadvantages and you should choose the one that suits your lifestyle best.
Pump-driven machines also come in a variety of sizes and price. The most expensive models are typically super-automatic and have multiple boilers that separate the water used to steam and brew. These models have heat exchangers which can be set at different temperatures to allow for a variation in the flavor. This feature is ideal for the busy barista at home, but it increases their price. The middle option is a semi-automatic which is a great value but doesn't offer the same consistency and flexibility as other alternatives.
Steam-driven
Steam-driven machines employ a simple mechanism to produce an intense espresso. Inside an airtight tank steam is heated to create pressure, which is then transferred to the coffee grounds for brewing.
espresso machine with milk frother is similar to the process used inside a stovetop Moka pot. These machines are in use today due to their cost-effectiveness and their compactness. However, these machines aren't able to produce the 9 bars of pressure required for true espresso. These models are ideal for those who are just beginning making espresso at home or those who don't worry about making the perfect espresso.
A very early example of a steam-driven machine is the 1878 compensation siphon balancer created by German engineer H. Eicke. The steam generated by this device pushes boiling water through a filter of ground beans. It is then depressurized by the heat from an open flame spirit burner. This process produces a powerful shot but does not meet the standards of consistency that many espresso drinkers prefer.
Luigi Bezzera patented improvements in 1901 which led to the next breakthrough. The design of his invention allowed him to reduce the temperature of the boiler. This enables more stable temperature and pressure control. Bezzera also included the piston-based device, which made the machine semi-automatic. The only problem was that it required the barista a while to grind, measure and tamp the beans manually.
This led to the creation of a pump-driven espresso machine. Unlike the older steam-driven machines that were heated by an open flame, the new kind of machine is equipped with an electric pump that is capable of generating the high pressure required for the brewing of espresso. The machines can take water from a cold line, which is common in commercial installations. They can also use an individual water tank that has to be filled manually.
The machines also come with two temperature settings that can be controlled by one button. One button activates the brew thermostat, while the other switch on the steam thermostat. This kind of machine is more accurate than older steam-driven machines and can provide consistent shots at less than the cost of more expensive models.
Semi-automatic
Semi-automatic machines are the best option for those looking to make espresso quickly and easily. It eliminates barista training by automatizing the process of grinding, tamping and extraction to ensure consistent results. It does not complete all the work for you. You still have to grind the beans, then tamp them down in the portafilter, then push the water through.
This is the reason that many coffee lovers prefer semi-automatic machines, since they like the feeling of being more in control during the brewing process. They also come with an affordable price compared to their fully automated counterparts, and they tend to be more reliable as well.
These espresso machines are typically found in non-specialty shops and in the homes of coffee drinkers who are willing spend more money for convenience. Dual boilers permit the steam and brewing to be kept separate. One is used to heat while the other is used to make your preferred beverage. Some even have an integrated grinder, which can be a big time-saver for the user.
However, the built-in grinder often has a limited number of settings, which can be frustrating for those inclined to play around with the process of making espresso to create their own personal favorite. It is better to pair a semi automatic espresso machine with an external grind for total control over the grind size.
If you're interested in an espresso machine that is semi-automatic, look for one with an extremely quiet electric pump, and a temperature controller that allows precise temperature regulation. The PID is an element of technology that's usually used in immersion circulators as well as high-end toaster ovens. It can help stabilize a brewing kettle by analyzing the temperature fluctuations throughout the heating process.
Furthermore, a high-quality semi-automatic machine must have a powerful enough steam wand that can create microfoam. It should also be capable of switching between steaming and brewing modes with ease (if it does not have dual boilers). A semi-automatic machine with all of these features is an excellent choice for those who don't want to learn how to make high-quality cafe drinks however nonetheless want to play.
Manual
Manual espresso machines employ levers to push pressurized water over a bed of finely ground coffee, resulting in extremely concentrated shots. They are less expensive than semi-automatic or fully automatic machines which is why they are popular with coffee drinkers.
Manual espresso machines require more attention and skill from the operator in order to maximize their potential. Making the right choice in a grinder, ensuring that the brew ratio is right and knowing how to properly dose and make sure your grounds are tamping properly are some of the things you'll need to know before making use of a manual machine.
While some find the process of learning manual machines difficult and frustrating for those who have the right knowledge are able to make it worth the effort. CHOICE's in-house expert barista, Adrian Lini, says that if you have the right equipment and patience to learn, a manual espresso maker will give you the best espresso experience.
In recent times, the hand-operated espresso machine has changed in its design and function. It now comes with more sophisticated features, such as digital pressure gauges that allow users to monitor pressure during extraction. Charles, who works for Flair Espresso, says that these machines can be connected with Bluetooth devices to digitally create graphs of flow rates. This allows users to understand how changing variables in extraction can impact the final result.
There are two main kinds of manual espresso machines: direct and spring piston. Direct levers have a spring inside their group heads, which helps increase pressure while brewing. They're more expensive than spring-assisted machines but they're still simpler to use.

Springs piston machines are limited to the steam valve inside their group head. They're easier to use than direct lever machines however they don't offer as much control over the process of brewing. The ideal machine for you will be based on your budget and personal preferences. Whatever you decide to go with a manual espresso machine will require a few key components that include an able filter as well as a coffee mill and kettle.
