Espresso Machines - Which One is Right For Your Home?
The most effective espresso machines will be easy to use, clean and provide balanced shots. What are the steps to choose the most efficient espresso machine for your home?
This Breville model is ideal for those who don't want to learn barista skills but still want to enjoy great coffee at home.
Pump-driven
Pump-driven machines rely on an electric pump to generate the force needed to brew 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). Pumps are usually solenoid pistons that can produce high pressure. Certain espresso machines that are driven by pump systems have a fixed flow rate, while others allow you to alter the pre-infusion or brewing pressure.
The most well-known type of machine, they are an excellent choice for anyone who wants to make coffee of high quality quickly and consistently. They are simpler to clean and maintain than other models, however they require electricity and a space near an outlet.
They come in two basic types: semi-automatic and super-automatic. Semi-automatics allow you to control the amount of time the shot is pulled by using either a manual switch or a feature that can be programmed. You can also control the grind setting, and tamp down the coffee. Certain semi-automatics feature rotary motors as well as others that vibrate. Rotary pumps are quieter however, they require constant flow of pressurized liquid.
A vibrating pump, on the contrary, begins with a quiet start. However, it can sound like a scream once water is added to the machine. Both have advantages and disadvantages and you should pick the one that fits your lifestyle the best.
Pump-driven machines are available in a range of sizes and price ranges. The most expensive machines are typically super-automatic, and have multiple boilers that separate the water for brewing and steaming. They also have heat exchangers which can be set at different temperatures to allow for variations in flavor. This additional feature makes them an ideal choice for the busy home barista however, it can increase their price. The middle option is a semi-automatic which is a great value but does not offer as much consistency and versatility as other options.
Steam-driven
Steam-driven machines use an easy system to make an intense espresso. Inside an airtight tank steam is heated to create pressure that is transferred to the coffee grounds for brewing. This is similar to the process used inside a stovetop Moka pot. These machines are still in use today because of their cost-effectiveness and compactness. These models are not able to reach the 9 bars of pressure required for a truly espresso. This makes them best for those who are just getting started with home brewing or aren't concerned about making the perfect espresso.
The balancer balancer compensation from 1878 developed by German engineer H. Coffeee is a early steam-driven machine. Steam is produced by this machine, which is used to push boiling beans through an aerator. The water is then depressurized with heat from an open flame. This method produces a strong shot, but doesn't meet the high standards of consistency that many espresso drinkers like.
The next step forward was Luigi Bezzera's 1901 patent improvements. His invention was able lower the temperature of the boiler, which allowed for more constant temperature and pressure control. Bezzera also included the piston-based device, which made the machine semi-automatic. The only issue 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. Unlike the older steam-driven machines, which were heated with an open flame, this type of machine has an electric pump that is capable of generating the high levels of pressure required for the brewing of espresso. The machines can take water directly from an existing cold water line which is common in commercial establishments or they can utilize an additional tank that is filled with water by hand.
They also have two temperature settings controlled via a push button. One of these buttons is activates the brew thermostat, and the other switches on the steam thermostat. This type of machine can make consistent shots at only a fraction of the price it costs compared to older steam-driven models.
Semi-automatic
If you're seeking a simple method of making espresso with less effort The semi-automatic machine could be the answer. It can eliminate barista training by automatizing the process of grinding, tamping and extraction to produce consistent results. However, it can't take care of everything for you. You'll must grind the beans and then tamp them in the portafilter prior to the water is pushed through them.
Many coffee lovers, both professional and amateur, prefer to use semi-automatic machines for this reason, as they like the feeling of being more involved in the brewing process. They also come with less cost than their fully-automated counterparts, and they are also known to be more reliable too.
These espresso machines are typically found in shops that are not specialty and at the homes of coffee drinkers who are willing to pay more for convenience. Dual boilers allow steam and brewing to remain separate. One is used for heating while the other is used to make your preferred beverage. Some have even a built-in grinder that could be a major time-saver for the user.
The espresso grinder that comes with the machine is usually limited in its settings, which can be a problem for those who want to modify the process of making their own espresso. It is better to use a semi-automatic espresso machine with an external grind for full control over the grind size.
If you're considering a semi-automatic espresso machine, ensure that you select one with a high-quality, low-noise electric pump and precision temperature regulation via a PID controller. The PID is typically found in high-end toaster and immersion circulators. It helps stabilize a brewing system by measuring temperature fluctuations during the heating process.
Furthermore, a high-quality semi-automatic machine needs to have a powerful enough steam wand that can create microfoam. It should also be able to switch between steaming and brewing modes quickly (if it doesn't include dual boilers). A semi-automatic machine with all these features can be an excellent option for those who don't wish to learn how to make high-quality cafe drinks however still want to have fun.
Manual
Manual espresso machines are operated with levers that push coffee grounds pressurized through the bed. This produces highly concentrated shots. They are generally less expensive than semi-automatic and fully automated counterparts, making them a favorite for those who appreciate a fine cup of coffee.
Manual espresso machines require more focus and experience from the operator in order to maximize their capabilities. It is also important to select the correct grinder and make sure that the brew percentage is correct.
While some people may find the learning curve operating a machine manual difficult but for those who have the right capabilities, it's worthwhile. Our expert barista in-house at CHOICE, Adrian Lini, says that if you've got the right tools and the patience to learn how to operate a manual espresso machine, it can give you the best espresso experience.
In recent times, espresso machines operated by hand have grown in both form and function with more sophisticated features like digital pressure gauges that allow users to monitor the pressure while extracting. Charles, who is employed by Flair Espresso, says that the machines can be paired with Bluetooth devices to draw graphs of flow rate. This allows users to understand how the changing variables during extraction can impact the final outcome.
There are two main types of manual espresso machines that are direct and spring piston. Direct levers are equipped with a spring in their group heads to increase the pressure when making. Although they are more expensive and more difficult to use than spring-assisted machines.
Springs piston machines only have the steam valve in their group head. They're much easier to use than direct lever machines but do not provide as much control over the brewing process. The ideal machine for you will be based on your budget and personal taste. Whatever you choose a manual espresso machine will require a few essentials, including an able filter as well as a coffee mill and kettle.
