A Good Housekeeping 2022 Espresso Machine winner, this innovative machine utilizes smart dosing technology to weigh and dispense the perfect amount of ground coffee for each shot. It also includes a milk frothing wand that excelled in our tests for producing steaming milk.
The Basics
Espresso machines are a wonderful addition for any home or office. They are able to make numerous drinks, including cappuccinos and lattes. They work by pushing hot water through ground coffee under high pressure. This produces a concentrated shot of coffee that is extremely flavorful. It also contains a high amount of caffeine that can be a very effective stimulant.
These kinds of machines come in a variety of sizes, from small models that are perfect for homes to larger ones specifically designed for commercial use. They are available in both semi-automatic as well as manual designs. Manual machines require the operator to manually manage the flow of water and pressure while semi-automatic models feature an inbuilt pump that handles this for you. Certain semi-automatic models feature grinders, whereas others do not. The type of machine that you choose will depend on your budget and personal preferences.
A manual espresso machine works by allowing the user to use a handle to push water through grounds that are placed in a filter basket. This type of machine is typically referred to a macchinetta or caffettiera, and it is the most popular type of espresso maker. It has an under-chamber that holds the water and the top chamber, which houses an aluminum filter. When it is heated the steam from the water is forced through the grounds before it is pumped into the top chamber, from where the brewed espresso is ready to serve.
Varieties
There are different types of espresso machines available based on your needs. There are semi-automatic, manual, and fully automatic espresso machines. Each has its own method of making an espresso shot as well as a variety of other beverages such as cappuccinos or lattes.
The first machines were not fully automated. They required the user to operate the lever to create the necessary pressure to take the shot. Although they are still available, they are not as common because they require a lot of effort and can be tiring to operate. Modern espresso machines produce pressure by using a variety of mechanisms which include screw, push and see-saw designs. This allows users to regulate pre-infusion, volume of water and pressure more precisely than a lever machine.
Pump-driven espresso machines are similar to stovetop mokapots, however, they use an electric pump to press the grounds of coffee, instead of steam. They are equipped with a boiler that heats the water to boiling and a pump presses it through a group head into the coffee. They are the most popular kinds of espresso machines and they are usually cheaper than other varieties.
Semi-automatic espresso machines incorporate the best features of both pump-driven and manual espresso machines. They allow the user to grind and tamp the beans, however, a motor regulates the pressure to ensure uniformity during extraction. Some have a separate chamber for heating and frothing milk.
Functions
Commercial espresso machines can make a wide variety of coffees, such as espressos at the press of an button. They use pre-packaged pods which have been precisely dosed and packaged to produce one cup of coffee or espresso. These sleek machines do away with the need for grinders, dosing or tamping, which makes them a popular choice for busy offices. Because they do not have steam functions, a separate milk maker is required to make cappuccinos as well as lattes.
Many cafes across Europe utilized steam machines to boost production and decrease brewing time. However, the early machines were heated over an open flame, resulting in inconsistent pressure and temperature. The inventor Angelo Moriondo of Turin, Italy is credited with creating the first machine that was capable of brewing espresso without steam.
The most popular type of machine today is the pump-driven espresso machine. These machines utilize a portafilter to store the ground espresso beans. When the valve switches to the espresso position and the espresso is extracted from the water under 15 atmospheres of pressure from an heating vessel. After the brew is completed, the portafilter is taken out and the portafilter is emptied for cleaning.
Automated espresso machines automatize semi-automatic systems, controlling the extraction times based on internal or volumetric timers. They also remove the barista's ability to tamp or grind coffee, which can impact the quality of the final product.
Maintenance
Espresso machines aren't the most elegant part of a coffee shop but they are vital. How an espresso machine is maintained can influence the taste of your drinks therefore it is essential to keep up with a routine that includes daily cleaning descaling, cleaning, and regular water filter changes.
A clean espresso machine ensures that the flavor of your coffee won't be affected and your clients will have a wonderful experience. Keeping up with commercial espresso machine of cleanings and maintenance can help increase the life span of your espresso machine, ensuring it can last for a long time.
Use a damp, clean cloth to clean the portafilters and baskets once every shift to remove any residue or oils. In this process, backflush the gasket in the portafilter (the seal between the portafilter and the group head) by inserting a brush made of nylon into the gasket, and moving it around to eliminate any accumulation. Rinse off the gasket then run it again until the water runs clear.
Mix espresso machine cleaner with water in a container according to the instructions of the manufacturer once a week, or whenever needed. Then soak portafilters and baskets in the cleaning solution overnight. If your espresso machine comes with a steam wand and screen, remove them from the collection using an screwdriver. Soak them separately in the cleaning liquid.
