The Basics

Espresso machines are a great addition to any office or home. They can be used for many different drinks, including lattes or cappuccinos. They work by forcing hot water through ground coffee under pressure. This results in a concentrated shot that is full of flavor. It also has a very high amount of caffeine that can be a very effective stimulant.

These machines are available in an extensive variety of sizes, ranging starting with small models for domestic use to larger ones to serve commercial needs. They are available in semi-automatic and manual versions. Manual machines require the user to regulate the flow of water and pressure and semi-automatic models include an integrated pump that can do this for you. Some semi-automatic models include a grinder, while others do not. The type of machine that you choose will be determined by your budget and personal preferences.

A manual espresso machine operates by allowing the user to move a handle to push water through the grounds that have been placed in a filter basket. This kind of machine is often called caffettiera or macchinetta and is the most popular type of espresso maker. It has a bottom chamber that holds the water, and a top chamber that houses an aluminum filter. When it is heated the steam from the water is pushed through the grounds, and finally into the top chamber, from where the espresso is ready to serve.

Varieties

Depending on your needs the options are endless. You can choose among a variety of espresso machines. There are semi-automatic, manual and fully automated espresso machines. Each machine has its own unique method of making espresso shots and other drinks such as lattes and cappuccinos.

The first machines were not fully automated, requiring the user to manually operate a lever that produced the pressure needed for a shot espresso. They are still in use, but they are less frequent due to the amount of effort required and the fatigue they can cause. Modern espresso machines produce pressure by using a variety of mechanisms such as screw, push and see-saw designs. This lets the user manage pre-infusion and water volume more precisely than the lever machine.

A pump-driven espresso machine is akin to the stovetop moka pot, but it uses an electric motor instead of steam to press the grounds. They are equipped with a boiler that warms the water until it reaches a boiling point and a pump pushes it through a group head to the coffee. They are the most sought-after type of espresso machine black Friday machines and are usually less expensive than other types.

Semi-automatic espresso machines bring together the best aspects of both pump-driven and manual espresso machines. They allow you to grind the beans and then tamp them, but a motor regulates the pressure for consistency. Some models have a separate compartment for heating and frothing milk.

Functions

Commercial espresso machines can make a broad variety of coffees, including espressos at the press of an button. They make use of pre-packaged pods that have been precisely dosed and packed to make one cup of coffee or espresso. These compact machines remove the need for a grinder, dosing and tamping, which makes them an ideal choice for busy offices. However, since they also lack steam functions, you'll need a separate milk frother to make cappuccinos and lattes.

Many cafes across Europe utilized steam machines to boost production and cut down on brewing times. The early machines were heated by an open flame which led to unbalanced pressure and temperature. The inventor Angelo Moriondo of Turin, Italy is believed to have invented the first machine capable of brewing espresso without using steam.

The most common kind of espresso machine available today is a pump-driven system. They use a portafilter to store the ground espresso beans. When the valve is turned to the espresso position it extracts the espresso by water that is under 15 atmospheres of pressure from a heating vessel. After the brew process is complete, the portafilter is taken out and then emptied to be cleaned.

Automated espresso machines automatize semi-automatic systems, by controlling the extraction time based upon internal or volumetric timers. They also remove the barista's capacity to tamp and grind coffee, which can impact the quality of the finished product.

Maintenance

Espresso machines are not the most beautiful part of the coffee shop, but they are incredibly important. How you maintain the espresso machine will impact the taste and quality of your drinks.

A clean espresso machine will ensure the flavor of your coffee isn't compromised and that your customers' experience is enjoyable. The regularity of cleanings can extend the life of your espresso machine.

Use a damp cloth to clean the baskets and portafilters once every shift to remove any residue or oil. During this time backflush the gasket of the portafilter (the seal between the portafilter's head and the group head) by inserting a nylon toothbrush into the gasket, and moving it around to remove any accumulation. Rinse the gasket in water and then run it through until the water runs clear.

Mix espresso machine cleaner and water in a container as per the instructions of the manufacturer at least once a week or as needed. Then soak the portafilters, grates, and baskets for a night in the cleaning solution. If your espresso machine is equipped with a steam wand and screen, remove them from the group using a screwdriver. In separate soaking, soak them in the cleaning solution.
