Five Machines Espresso Machines Lessons From Professionals
espresso makers - Which One is Right For Your Home?
The best espresso machines are easy to use, clean, and produce balanced shots. But how do you determine which one is the right machine for your home?
This Breville model is perfect for those who don't wish to learn barista skills but still want great 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, common with commercial installations or a reservoir that has to be filled manually (common with household and smaller commercial espresso machines). Pumps are typically solenoid pistons that can generate high pressure. Some espresso machines driven by pumps have a fixed flow control and others allow you to adjust the pre-infusion and/or brewing pressure.
The most popular type of machine, they are a great option for those who want to make quality coffee quickly and consistently. These machines are easier to maintain and clean than other types, but they do require electrical power and a place near an outlet.
They come in two basic types: semi-automatic and super-automatic. Semi-automatics let you regulate the length of time that the shot is pulled by using either a manual switch or a feature that can be programmed. In addition, you are able to control the grind setting and make sure that the coffee is tamper-proof. Certain semi-automatics feature motors that are rotary and others are vibrating. Rotary pumps are quieter, but they require a constant flow of pressurized liquid.
In contrast, a vibration pump can start off quiet but it can soon sound like a scream when the machine is fed with water. Both have pros and cons, and you should pick one that suits your lifestyle.
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 to separate the water used for steaming and brewing. The heat exchangers in these models can be set to different temperatures, which can result in some variation in the flavor of the espresso. This extra feature makes them an ideal choice for the busy barista at home, it does increase the cost. Semi-automatics are a good middle option. They aren't expensive but they don't provide the same level of consistency and versatility of other options.
Steam-driven
Steam-driven machines employ an easy mechanism to make a strong espresso. In an airtight container, hot water is steamed to create pressure which is then transferred to the coffee grounds to make espresso. This is similar to the process that occurs inside the stovetop moka kettle and these machines are still used today for their affordability and compact size. However, these models do not have the ability to reach 9 bars of pressure required for authentic espresso. This makes them best for those just getting started with making espresso at home or aren't concerned about making the perfect cup of espresso.
The balancer balancer compensation from 1878 developed by German engineer H. Eicke is a early steam-driven machine. Steam is produced by this machine, which pushes boiling beans through filters. The water is then depressurized with heat from an open flame. This process produces a powerful shot, but it doesn't provide the quality of consistency that many espresso enthusiasts prefer.
The next breakthrough came with Luigi Bezzera's 1901 patented improvements. His invention allowed him to lower the temperature in the boiler. This allows for a more stable temperature and pressure control. Bezzera also included the piston device to make the machine semi-automatic. The only problem was the barista needed to grind and measure beans manually.
This led to the development of a pump-driven espresso machine. This brand new espresso machine, unlike those older steam-driven machines, which were heated by an open flame, features an electric pump capable producing the high levels of pressure needed for the brewing of espresso. These machines can accept water from a cold line which is common in commercial establishments. They also have the option of using an additional water tank that must be filled manually.
The machines also come with two temperature settings controlled via a push button. One button activates the brew thermostat, while the other switch on the steam thermostat. This type of machine is more precise than older steam-driven machines and can make consistent shots for only a fraction of the price of the more expensive models.
Semi-automatic
For those who are looking for an easy way to brew espresso with less effort, the semi-automatic machine is the answer. It eliminates barista training by automating the process of grinding, tamping and extraction to ensure consistent results. But it doesn't complete the entire process for you. You'll still must grind the beans and then tamp them in the portafilter before the water is pushed through them.
Many coffee lovers, both professional and amateur, prefer semi-automatic coffee makers for this reason, as they enjoy being more involved in the brewing process. These machines are also cheaper than their fully-automatic equivalents and are generally more reliable.
These espresso machines are typically located in shops that are not specialty shops and at the homes of coffee drinkers who are willing to spend more for convenience. They feature dual boilers so that the steam and brewing water are kept separate, while one is heating up and the other is used to create the beverage you prefer. Some have even a built-in grinder, which can be a big time-saver for the user.
The built-in espresso grinder is often limited in its settings, which can be a problem for those who want to modify the process of brewing their own espresso. A better solution is to pair a semi-automatic espresso machine with an external grinder to have complete control over the size of the grinder and dosage.
If you're looking to purchase a semi-automatic espresso machine, ensure you choose one that has a high-quality, low-noise electric pump and precision temperature regulation via a PID controller. The PID is usually used in high-end toasters and immersion circulators. It assists in stabilizing a brewing system by measuring variations in temperature during the heating process.
A decent semi-automatic espresso maker should also have a steam wand powerful enough to make microfoam and the ability to switch between steaming and brewing modes quickly (if it doesn't have two boilers). With all these options, a top-quality semi-automatic espresso maker is an excellent choice for those who wish to get rid of the hassle and expense of learning how to make cafe-quality drinks but still appreciate some flexibility with the process.
Manual
Manual espresso machines operate with levers which push the coffee grounds through a bed. This results in extremely concentrated shots. They are generally less expensive than their semi-automatic and fully automatic counterparts, which makes them popular among discerning coffee lovers.
Manual espresso machines require greater attention and skill from the operator to maximize their capabilities. You'll also have to select the right grinder and ensure that the brew proportion is correct.
While some people find the learning curve of manual machines challenging and difficult, those with the right knowledge can make it worth the effort. Adrian Lini, CHOICE's expert barista says that if one has patience and the right tools, a manual machine can make the best espresso.
In recent years, the hand-operated coffee machine has improved in both its form and function. It now includes more sophisticated features, including digital pressure gauges, which allow users to monitor the pressure during extraction. Charles, who is employed by Flair Espresso, says that these machines can be used with Bluetooth devices to digitally draw graphs of flow rate. This allows users to understand how changing variables in extraction can impact the final result.
There are two main types of manual espresso machines that are direct and spring piston. Direct levers have a spring in their group heads to help boost pressure during making. While they are more expensive but they are also easier to use than spring-assisted machines.
Springs piston machines, on the other hand, have nothing in their group heads other than the steam valve. They're much easier to use than direct lever machines, but don't provide as much control over the brewing process. The right machine for you will be based on your budget and your personal preferences. Whichever one you choose a manual espresso machine will need a few essential accessories, such as kettles, a coffee grinder, and a portafilter with the option of removing a dispersion filter made of metal.
