This unique machine, a Good Housekeeping 2022 Espresso winner makes use of smart dosing to determine and disperse the right amount of coffee ground for each shot. It also has a milk froth that did well in our tests.

The Basics

Espresso machines are an excellent addition for any home or office. They can be used to create numerous drinks, including lattes and cappuccinos. They work by pushing hot water through ground coffee under high pressure. This creates a concentrated shot that is bursting with flavor. It also contains a high concentration of caffeine, which can be a powerful stimulant.

These machines are available in a wide range of sizes, from small models for home use to larger ones for commercial purposes. They are available in both manual and semi-automatic designs. Manual machines require the operator to control the flow of water and pressure while semi-automatic models come with an inbuilt pump that will do this for you. Certain semi-automatic models feature grinders, while others do not. The type of machine you select will be determined by your budget and personal preferences.

The manual espresso machine operates by turning a handle, which forces water through the grounds inside an evaporator. This type of machine is often called a macchinetta or caffettiera, and it is the most well-known type of espresso maker. It has an inner chamber that holds the water and an upper chamber with the filter made of metal. When it's heated, the steam from the water is forced through the grounds and into the top chamber, where the brewed espresso is ready to serve.

Varieties

There are various 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 method of making espresso shots and a variety of beverages like cappuccinos or lattes.

The first machines were not completely automated, requiring the user to operate the lever manually that created the pressure required to pull a shot of espresso. These machines are still available, but they are less common due to the effort required and the stress they can cause. Modern espresso machines employ various mechanisms to create pressure such as screw, push and see-saw designs. This allows users to manage pre-infusion, water volume and pressure more precisely than a lever machine.

Pump-driven professional espresso machine machines are similar to stovetop mokapots however, they use an electric pump to press the coffee grounds instead of steam. They are equipped with a boiler, which heats the water to boiling, and then a pump pushes it through a group head into the coffee. They are the most sought-after kinds of espresso machines, and are usually less expensive than other varieties.

Semi-automatic espresso machines bring together the best aspects of both pumps-driven and manual espresso machines. They allow the user to grind and tamp the beans however, a motor controls the pressure to ensure consistent extraction. Some have a separate chamber for heating and the frothing of milk.

Functions

Commercial espresso machines can produce a wide range of coffees, which includes espressos at the press of a button. They use pre-packaged coffee pods that are precisely dosed and then packed to make an espresso cup or coffee. These machines are streamlined and eliminate the need for grinders, dosing or tamping, which makes them popular for busy offices. However, as they lack steam functions, you'll require an additional milk frother in order to make cappuccinos and lattes.

Many cafes in Europe employed steam machines to increase production and speed up brewing. But the first machines were heated with an open flame, which resulted in inconsistent temperature and pressure. Inventor Angelo Moriondo of Turin, Italy is credited with establishing the first machine capable of making Mini Espresso Maker without using steam.

The most commonly used type is the pump-driven espresso machine. They have a porta-filter that the ground beans of espresso are inserted. When the valve is set to the espresso position, the espresso is extracted through water at 15 atmospheres of pressure coming from an heating vessel. After the brew is completed, the portafilter is removed and emptied to be cleaned.

Automatic espresso machines add automation to semi-automatic systems by controlling the extraction time based on volumetric or internal timers. They also eliminate the barista’s ability to grind or tamp coffee, which could affect the quality of the final product.

Maintenance

Espresso machines may not be the most glamorous equipment in a cafe, but they're extremely important. The way you maintain the espresso machine will impact the taste and quality of your drinks.

A clean espresso machine will ensure that the flavor of your coffee doesn't suffer and your customer's experience is great. A regular schedule of cleanings can prolong the life of your espresso machine.

Clean the portafilter and baskets at every shift, using a damp, clean cloth to remove the oils and residue left behind. During this time backflush the gasket in the portafilter (the seal between the portafilter and the group head) by inserting a nylon toothbrush into the gasket, and moving it around to dislodge any buildup. Rinse the gasket with water and run it through until the water is clear.

Mix espresso machine cleaner with water in a container according to the instructions of the manufacturer every week, or as required. Then soak the portafilters gratings, and baskets overnight in the cleaning solution. If your espresso maker has steam wands, remove the screen and wand from the group with the help of a screwdriver, and soak them separately in the cleaning solution.
