Consider owning an automatic espresso machine if you are a passionate coffee lover. You can make high-quality coffee drinks with these appliances in minutes. But have you ever wondered how automatic espresso machine works? This blog post will explore the mechanics behind these fascinating devices so that you can appreciate them even more.
How Automatic Espresso Machine Works | Let’s Take a Look
We must break down their main components and processes to understand how automatic espresso machines work. The first component is the water reservoir, where the machine stores the water for brewing coffee.
Most automatic espresso machines come with a removable tank that you can refill as needed, while others have direct plumbed-in connections for a steady water supply. The water must be clean and filtered to ensure the best taste.
The machine will pump water through a heating element to heat it to the right temperature for brewing. There are three types of heating elements: boilers, Thermo blocks, and coils.
Portafilters, small metal baskets that hold coffee, mix water with ground coffee.
The portafilter is attached to a group head, a metal block with valves that control the water flow. When the user selects a coffee drink, like espresso, cappuccino, or latte, the computer opens the valves to allow water to flow.
But how does the machine know which beverage to make? Here’s where the computer and user interface come in. Most automatic espresso machines have a screen or a set of buttons that display the available beverages and allow the user to select their preferences.
The computer will use this information to adjust the amount of water, coffee, and milk for each drink.
The final component of an automatic espresso machine is the milk frothing system, which is optional but essential for milk-based beverages. Depending on the machine’s features, the system can be a steam wand, a frothing chamber, or an automatic milk carafe.
The milk frothing system will suck in cold milk and heat it while blending it with steam to create a rich, creamy foam. The frothed milk can be added to the coffee or served independently. Now you completely know about how automatic espresso machine works.

How Do You Make Espresso With An Automatic Machine?
Making espresso with an automatic espresso machine is a relatively straightforward process. Follow these steps:
Step 1: Prepare the machine
Fill the reservoir with fresh, cold water and plug it in. Get it to the right temperature for brewing by heating it.

Step 3: Prepare the portafilter
The portafilter is the handle-like device that holds the coffee grounds. Remove it from the machine and clean it if necessary. Depending on your machine, you may have a single or double-shot portafilter. Choose the one that suits your preference.
Step 4: Dose and distribute the coffee
If your machine has a built-in grinder, you can usually set the desired coffee dose. If not, measure the appropriate amount of coffee using a scale. Distribute the coffee evenly in the portafilter and press it down firmly with a tamper. The coffee should be evenly distributed and leveled.
Step 5: Insert the portafilter
Place the portafilter back into the machine. Make sure it locks into place securely.
Step 6: Start the brewing process
Depending on your machine, there may be different buttons or settings to initiate the brewing process. Typically, there will be a button for a single shot and another for a double shot. Select your desired option.
Step 7: Collect the espresso
Position your cups or shot glasses under the machine’s spouts. The machine will begin extracting the espresso and flow into the cups. The brewing process usually takes around 20 to 30 seconds.
Step 8: Stop the extraction
Once you have collected the desired amount of espresso, stop the extraction by pressing the corresponding button or turning off the machine.
Step 9 Clean the portafilter
After brewing, remove the portafilter from the machine and discard the used coffee grounds. Rinse the portafilter and wipe it clean.
Step 10: Enjoy your espresso
Serve and enjoy your freshly brewed espresso immediately. You can drink it on its own or use it as a base for other espresso-based drinks.
