Espresso Machines – Which One is Right For Your Home? Coffeee are easy to use, simple to clean and able to make well-balanced and rich shots. How do you pick the best espresso machine for your home? This Breville model, with its quick-heating thermocoil design and digital convenience is perfect for a person who doesn't have the time to learn barista skills but wants good coffee at home. Pump-driven Pump-driven machines use an electric pump to provide the force needed to prepare espresso. These machines either accept water directly from the mains, which is typical in commercial installations, or they have a reservoir which must be manually filled (common for home espresso machines and smaller commercial espresso machines). Pumps are usually solenoid pistons that can produce high pressure. Some pump-driven espresso machines have a fixed flow regulation, while others let you adjust the pre-infusion and/or the brewing pressure. The most popular kind of machine, these are a great option for those looking to make coffee of high quality quickly and consistently. These machines are simpler to maintain and clean than other types, but they require electricity and space near an outlet. They come in two basic varieties: semi-automatic and super-automatic. Semi-automatics let you control how long the shot is pulled by using the manual switch or programable function. You can also alter the grind setting, and then tamp down the coffee. Certain semi-automatics feature rotary motors and others are vibrating. Rotary pumps are quieter, however, they require a constant flow of pressurized liquid. A vibrating pump, on the contrary, begins quite quietly. However, it can sound like a scream when water is added to the machine. Both types have their advantages and disadvantages and you should pick the one that suits your lifestyle best. Pump-driven machines come in a range of sizes and price ranges. The most expensive machines are usually super-automatic, and have multiple boilers that separate the water for brewing as well as steaming. The heat exchangers on these machines can be set to various temperatures, allowing for some variations in the flavor of the espresso. This is a great feature for the busy barista working at home, but it increases their price. Semi-automatics are a good middle place. They aren't expensive but they don't provide the same consistency and versatility of other alternatives. Steam-driven Steam-driven machines use a simple system to produce a powerful espresso. In a sealed airtight container hot water is steamed to create pressure which is then transferred into the coffee grounds. This is similar to what happens inside the stovetop moka kettle and these machines are being used for their value and small size. These machines aren't able to reach the 9 bar pressure needed to make a true espresso. These models are ideal for those who are just beginning with homebrewing, or who don't care about making the perfect espresso. One of the earliest examples of a steam-driven machine is the 1878 compensation siphon balancer created by German engineer H. Eicke. Steam is created by this machine, which is used to push boiling beans through a filter. The water is depressurized using heat from an open flame. This produces a powerful shot, however it isn't up to the standard of consistency that many espresso lovers would prefer. Luigi Bezzera patented improvements in 1901 that led to the next breakthrough. The design was able to lower the temperature of the boiler, which allows for more consistent temperature and pressure control. Bezzera added a piston device to help make this machine semi-automatic. The only problem was the barista needed to grind, measure, and tamp beans manually. This led to the development of a pump-driven espresso machine. Contrary to older steam-driven machines, which were heated with an open flame, this new type of machine uses an electric pump that is capable of producing the high pressure required for the brewing of espresso. These machines can either accept water directly from the cold water line typical in commercial facilities, or they can use an additional tank that is filled with water by hand. The machines also come with two temperature settings that can be controlled by 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 make consistent shots for a fraction of the cost of the more expensive models. Semi-automatic For those who are seeking a simple way to brew espresso with less hassle the semi-automatic machine is the answer. It eliminates the need for barista-level education by automatizing the grinding extraction, and tamping processes to ensure consistent results. However, it doesn't do everything for you. You'll still need to grind the beans and tamp them in the portafilter prior to the water is being pushed through them. This is the reason that many amateur and professional coffee drinkers choose a semi-automatic machine, as they feel the satisfaction of having more control during the brewing process. They are also less expensive than their fully-automatic equivalents and tend to be more reliable. Espresso machines are usually located in shops that are not specialty shops and at the homes of coffee drinkers who are willing pay more for convenience. Dual boilers allow the steam and brewing to be kept separate. One is used for heating while the other is used to make your favorite beverage. Some models even come with a built-in grinder, which can be a huge time saver for the user. However the built-in grinder typically has a limited number 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 preferences. The best solution is to pair a semi-automatic espresso machine with an external grinder for full control over the size of the grind and the amount. If you're considering an espresso machine that is semi-automatic, make sure to look for one with a top-quality electric pump with low-noise, and precise temperature control via a PID controller. PID is a piece of technology that's typically used in immersion circulators as well as high-end toaster ovens. It can help stabilize a brewing boiler by measuring the temperature variations during the heating process. A good semi-automatic espresso machine should also have a steam wand that is powerful enough to create microfoam, and the capability to switch between steaming and brewing modes quickly (if it doesn't include dual boilers). A semi-automatic model with all of these features is an excellent option for those who don't want to learn how to make cafe-quality drinks however, they still want to have fun. Manual Manual espresso machines use levers to push pressurized water over a bed of finely ground coffee, resulting in highly concentrated shots. These machines are less expensive than semi-automatic or fully automatic machines and are therefore popular with coffee lovers. Manual espresso machines require more attention and expertise from the operator in order to maximize their potential. You'll also need to choose the right grinder and ensure that the brew percentage is correct. Although some people find the process of learning the manual espresso machine to be frustrating and difficult, those with the right skills can make it worth the effort. Our expert barista in-house at CHOICE, Adrian Lini, says that if you've got the right equipment and determination to learn how to operate a manual espresso machine, it can provide the ultimate espresso experience. In recent times, espresso machines operated by hand have seen a rise in both design and function with more sophisticated features like digital pressure gauges that let users monitor the pressure during extraction. Charles who works for Flair Espresso, says that these machines can be connected with Bluetooth devices to draw graphs of flow rate. This helps users understand how changing variables during extraction can impact the final outcome. There are two types of manual espresso machines which are spring-piston and direct. Direct levers have a spring inside their group heads that helps to increase the pressure when making coffee. Although they cost more, they can be easier to use than spring-assisted machines. Springs piston machines are limited to the steam valve within their group head. They are easier to use but don't offer as much control over the making process. The ideal machine for you will be based on your budget and personal taste. Whatever you decide to go with a manual-operated espresso machine will require a few key components, including an able filter and a coffee mill and kettle.
