A Good Housekeeping 2022 Espresso Machine winner, this cutting-edge machine uses a smart dosing system to weigh and dispense the ideal amount of ground coffee per shot. It also includes a milk frother that performed well in our tests.
The Basics
Espresso machines are a great accessory for any office or home. They can be used to prepare numerous drinks, including lattes and cappuccinos. They work by pushing hot water through ground coffee under pressure. This produces an intense shot of coffee that is extremely delicious. It also has a very high level of caffeine that can be an extremely effective stimulant.
They are available in a broad variety of sizes, ranging from compact models for home use to larger models to serve commercial needs. They are available in both semi-automatic and manual models. Manual machines require the user to control the flow of water and pressure, while semi-automatic models feature an inbuilt pump that handles this for you. Some semi-automatic machines include a grinder, while others don't. The kind of machine you select will depend on your budget and personal preferences.
Manual espresso machines work by allowing the user to use a handle to push water through the grounds that are placed in a filter basket. This kind of machine, also known as a caffettiera or macchinetta is the most sought-after design of espresso maker. It has a bottom chamber which holds the water, and a top chamber that houses the filter made of metal. When it's heated, the steam from the water is pushed through the grounds, and finally into the top chamber. There, the brewed espresso is ready to serve.
Variety
There are different types of espresso machines that are available based on your preferences. There are semi-automatic, manual and fully automated espresso machines. Each machine has its own unique method of making espresso shots and other drinks like cappuccinos and lattes.
The first machines were not fully automated, requiring the user to manually operate a lever that created the pressure required for a shot espresso. Although they are still available but they aren't as common because they require a lot of effort and can be exhausting to operate. Modern espresso machines utilize a variety of mechanisms to create pressure such as push, screw and see-saw designs. This allows the user to manage the pre-infusion process and the volume of water more precisely than the lever machine.
A pump-driven espresso machine is similar to the stovetop moka pot, however, it utilizes an electric pump instead of steam to press the grounds. They are equipped with a boiler, which brings the water to a boil and a pump pushes it through a group head into the coffee. They are the most well-known kinds of espresso machines, and are usually less expensive than other varieties.
Semi-automatic espresso machines combine the best aspects of both pumps-driven and manual espresso machines. They let the user grind and tamp the beans however, a motor regulates the pressure to ensure consistency during extraction. They also have a separate compartment which warms and froths milk and some are equipped with an integrated grinder.
Functions
Commercial espresso machines can make a broad variety of coffees, including espressos, with the click of one button. They use pre-packaged pods which are precisely dosed and packed to make one cup of espresso or coffee. These sleek machines remove the need for grinding, dosing and tamping, making them an ideal choice for busy offices. But, because they lack steam functions, you'll need separate milk frothers to make lattes and cappuccinos.
Many cafes in Europe utilized steam machines to boost production and reduce brewing times. But these early machines were heated with an open flame, resulting in inconsistent temperature and pressure. Angelo Moriondo, an Italian inventor from Turin is credited with developing the first machine to brew coffee without steam.
The most commonly used type of espresso machine today is a pump-driven system. These machines have a porta-filter that the ground beans of espresso are packed. When the valve is switched to the espresso position, the espresso is extracted from the water under 15 atmospheres of pressure coming from the vessel that heats. When the brew cycle is complete, the portafilter is removed and the drip tray emptied for cleaning.
Automatic espresso machines automate semi-automatic systems, controlling the extraction time based upon internal or volumetric timers. They also eliminate the barista's capability to tamp and grind coffee, which can impact the quality of the finished product.
Maintenance
Espresso machines might not be the most attractive equipment in a café, but they're extremely important. The way you maintain the espresso machine will impact the quality and taste of your drinks.
Clean espresso machines guarantee that the taste of your coffee won't be ruined and your customers will enjoy a pleasant experience. Regularly scheduled cleanings can extend the lifespan of your espresso machine.
Make use of a damp cloth and clean the baskets and portafilters once every shift to remove any residue or oils. During this time backflush the gasket in the portafilter (the seal between the portafilter's head and the group head) by inserting a nylon brush inside the gasket, and moving it around to dislodge any buildup. Rinse out the gasket and then repeat the process until the water runs clear.
Every week or when required, mix espresso machine cleaner into a container of water following the instructions of the manufacturer. Then soak portafilters and baskets in the cleaning solution for a night. If your espresso machine is equipped with a steam wand or screen, remove them from the collection using a screwdriver. Separately soak espresso coffee machine in the cleaning liquid.
