Espresso Machines – Which One is Right For Your Home? The best espresso machines are easy to use, simple to clean, and able to make well-balanced and rich shots. But how do you determine which one is the perfect machine for your home? This Breville model with its rapid-heating thermocoil design and digital convenience is ideal for someone who doesn't wish to learn barista skills but still wants to make great coffee at home. Pump-driven Pump-driven machines depend on an electric motor to generate the force needed to make espresso. These machines either accept water directly from the mains, as is the norm in commercial installations, or they contain a reservoir that has to be filled manually (common for espresso machines used in homes and smaller commercial espresso machine). The pumps used are typically solenoid-piston models 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. These are the most sought-after machines and are perfect for anyone who wants a steady, high-quality cup coffee. They are also easier to clean and maintain than other types of machines however, they require some electrical power and space near an outlet. There are two main 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 by using either a manual switch, or a programmable feature. Additionally, you can control the grind setting and to tamp the coffee. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter, however they require a constant flow pressurized liquid. A vibrating pump on the contrary, begins very quietly. However, it may sound like a scream once water is added to the machine. Both have pros and cons, and you should choose one that suits your lifestyle. Pump-driven machines are available in a variety of sizes and price ranges. The most expensive machines are typically super-automatic, and have multiple boilers that separate the water for brewing as well as steaming. These models have heat exchangers that can be set at different temperatures to allow for a variation in the flavor. This additional feature makes them a good choice for the busy barista at home however, it will increase the cost. The middle of the road is a semi-automatic which can be affordable but doesn't offer as much consistency and versatility as other options. Steam-driven A steam-driven machine uses a simple mechanism to produce an intense espresso. In a container that is airtight, hot water is steamed to create pressure which is then transferred into the coffee grounds. This is similar to the process that takes place inside a stovetop Moka pot. These machines are still in use today due to their affordability and their compactness. However, these machines don't have the capacity to produce the 9 bars of pressure required for true espresso. These models are best for those just starting out with homebrewing or those who don't worry about making the perfect espresso. One of the earliest examples of a steam-driven machine is the 1878 compensation siphon balancer designed by German engineer H. Eicke. Steam is produced by this machine, which is used to push boiling beans through an aerator. The water is then released by heating from an open flame. This technique produces a robust shot, but doesn't provide the quality of consistency that a lot of espresso drinkers like. Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. espresso coffee maker Coffeee allowed him to lower the temperature of the boiler. This enables more constant temperature and pressure control. Bezzera also had the piston-based device, which helped make the machine semi-automatic. The only issue was that the barista had to grind, measure, and tamp beans manually. This led to the creation of a pump-driven espresso machine. This new type of espresso machine, in contrast to the older steam-driven ones that were heated by an open flame, is equipped with an electric pump that is capable producing the high levels of pressure needed for the brewing of espresso. These machines can accept water directly from the cold water line common in commercial installations or they can utilize a separate tank that is filled with water manually. They also have two temperature settings that are controlled via a push button. One button activates the brew thermostat while another switch is for the steam thermostat. This kind of machine is more precise than older steam-driven machines, and can provide consistent shots at a fraction of the cost of more expensive models. Semi-automatic Semi-automatic machines are the best choice for those who want to brew their espresso quickly and efficiently. It eliminates the need for barista-level education by automatizing the grinding, tamping and extraction process to ensure consistent results. It doesn't do all the work for you. You'll still need to grind the beans, tamp them down in the portafilter and then push the water through. This is why many professional and amateur coffee lovers prefer semi-automatic coffee makers, because they feel the satisfaction of being in control of the process of making coffee. 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 commonly located in non-specialty coffee shops and in homes of casual coffee lovers who are willing to spend more for convenience. They have dual boilers, which means that the brewing water and steam are separated while one is heating up while the other is being used to prepare your beverage of choice. Some have even a built-in grinder that can be a big time-saver for the user. However the built-in grinder typically has a limited selection of settings that can be quite frustrating for those who are more than interested in playing around with the espresso-brewing process to make their own personal favorite. An alternative is to combine a semi-automatic espresso maker with an external grinder for complete control over the grind size and the amount. If you're looking for an espresso machine that is semi-automatic, look for one with a low-noise, high-quality electric pump, and a PID temperature control that allows precise temperature regulation. PID is a piece of technology that's commonly found in immersion circulators and high-end toaster ovens and helps stabilize a brewing kettle by measuring the temperature variations throughout the heating process. Furthermore, a high-quality semi-automatic machine needs to be equipped with a strong enough steam wand to create microfoam and be capable of switching between steaming and brewing modes quickly (if it doesn't have dual boilers). A semi-automatic machine with all these features can be an excellent choice for those who don't want to learn how to make drinks that are cafe-quality, but still want to have fun. Manual Manual espresso machines employ levers to push pressurized water across a bed of finely ground coffee, producing highly concentrated shots. These machines are less expensive than semi-automatic or fully automated machines which is why they are popular with coffee drinkers. Contrary to automated espresso machines, that are designed with ease-of-use in mind, manual espresso makers require more knowledge and focus by the operator to get the most of their potential. Selecting the right grinder, making sure that the brew ratio is in order, and understanding how to dose and tamp your grounds are just some of the things you'll need to know before using a manual machine. Although some people find the process of learning the manual espresso machine to be challenging and difficult for those who have the right skills can make it worth the 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 times, espresso machines operated by hand have improved in both appearance and function with more advanced features such as digital pressure gauges that let users monitor the pressure during extraction. Charles who is employed by Flair Espresso, says that these machines can be connected using Bluetooth devices to plot graphs for flow rate. This aids users in understanding how changing variables in extraction can affect the final result. There are two types of manual espresso machines that are direct and spring-piston. Direct levers include a spring in their group heads to help boost pressure during making. They're more expensive than spring-assisted machines, but can still be easier to operate. Springs piston machines On the other hand, don't have anything in their group heads except the steam valve. They're easier to use than direct lever machines however they do not provide as much control over the process of brewing. The choice of the best machine is dependent on your preferences and your budget. Whichever one you choose, an espresso machine that is manual will require a few necessary equipment, such as kettles, coffee grinder, and a portafilter with the option of removing a dispersion filter made of metal.
