It is not the latest or most intelligent model. There are already some marks of time on its metal casing, but in the eyes of my family, it is the most indispensable and vibrant member of the entire household. It has witnessed countless of our hurried mornings and accompanied many lazy weekend afternoons.

Morning Light and Preheating: A gentle Prelude to the Day

Usually, the father is the first person in the family to “talk” to him. When the first ray of sunlight filtered through the blinds and cast dappled shadows on the kitchen floor, Father would walk up to it and press the round power switch. With a soft “beep”, the indicator light of the coffee machine shone like an awakened eye, giving off a warm orange glow. Immediately after, a low and steady preheating sound came from inside the machine, and the water tank began to vibrate slightly, as if making the final preparations for a wonderful performance. This sound is more reassuring to us than any alarm clock. It seems to be saying: Everything is ready and a wonderful day is about to begin.

Mother is the “Director of water quality and bean products” at home. She always carefully fills the water tank of the coffee machine with filtered fresh soft water. “Good water brings out the soul of good coffee,” she often says. Then, she opened the sealed can containing coffee beans from different regions around the world. With a pleasant “whooshing” sound, the dark brown beans poured down like a waterfall into the bean bin at the top of the coffee machine. At that moment, the dry aroma of beans took the lead and quietly spread in the air, like the prelude to the opening of a symphony.

Grinding and Pressing: Awaken the sleeping elves

The true symphony begins when the “Grind” key is pressed. The father’s finger dropped, and the grinding wheel inside the coffee machine started up with a sound. The “buzzing” sound instantly filled the entire kitchen. This voice was powerful and forceful, as if it were a awakened lion. At the same time, a more intense and unrestrained aroma of coffee exploded and spread out. It was no longer the subtle dry aroma of beans, but a powdery scent with an oily texture and countless flavors. At this time, the child would always run into the kitchen, frown his nose and take a deep breath, saying, “I smell chocolate and nuts!”

After grinding, Father would take out the filter handle filled with coffee grounds. The freshly ground coffee powder is as fine as the wet sand on the beach, presenting a uniform caramel color. He gently smoothed it out with his fingers, then picked up the heavy metal powder press and pressed it down steadily and evenly. With a soft “click”, the coffee grounds were compacted into a smooth and flat “powder compact”. This process is filled with concentration and piety, like the most crucial step for a craftsman before completing a work. Finally, he skillfully inserted the filter handle into the coffee machine’s brewing head. With a crisp “click” of the lock, we knew that the curtain of the stage had officially risen.

Extraction and Steam: The Solo Moment of the Coffee Machine

Next up is the solo moment that belongs to this coffee machine completely.

Father pressed the extraction button marked “One cup”. In an instant, the powerful water pump started to work, and the 92-degree Celsius hot water, under a pressure of about 9 bar, penetrated the tight coffee powder cake. Everyone’s eyes will unconsciously focus on the area beneath the brewing head. At first, there was a few seconds of silence. Then, the first drop of dark coffee liquid struggled to stick its head out. After that, it merged into a fine stream and then turned into a shiny, viscous amber waterfall, trickling down into the preheated ceramic cup below.

This scene is never tiresome no matter how many times you look at it. The liquid that flowed out was not merely brown. Under the light, its edges glowed with a golden amber luster, and its core was a deep ochre. The most charming part is the layer of Crema that gradually accumulates and rolls on the liquid surface, like caramel-colored cream and as smooth as velvet. It carries the most charming flavor and aroma of coffee. As the coffee flowed out, there was a rhythmic “tick-tock” sound, like a lively percussion piece.

Almost at the same time, Father would turn on the steam knob on the side of the coffee machine. Another magic began – dry and powerful steam gushed out from the steam stick, making a sharp and forceful “hissing” sound. He inserted the milk jar containing iced milk, found the right Angle, and made the milk form a rapidly rotating vortex inside the jar. When milk mixes with steam, it makes a “sizzling” emulsification sound, its volume gradually expands and its temperature gradually rises. In no more than twenty or thirty seconds, a VAT of cold full-fat milk magically transformed into a VAT of high-quality milk foam that was smooth, warm and shimmering with a silky luster.

Fusion and sharing: The taste of home thus takes shape

When the rich flavor of espresso meets the smoothness of milk, it marks the final chapter of our family’s exclusive coffee ritual. Father would slowly pour the whipped milk foam into that cup of Espresso, which was as refined as essence, watching the brown and white collide and blend with each other. Sometimes, he would try to shake the milk jar and draw a simple heart or a leaf on the surface of the coffee. When the finished product is served on the table, it is no longer merely a cup of coffee, but more like a work of art infused with love and the morning light.

Our family sat around the dining table, each holding their own cup in their hands. I prefer lattes, my mother likes cappuccinos, and my father is loyal to his pure double espresso. In the air, the aroma of coffee and milk interweave, accompanied by the sound of relaxed conversations. What a nice day today. Where do you want to go for a walk this afternoon? What would you like to have for dinner tonight? … These ordinary family words, catalyzed by this cup of coffee, become particularly warm and touching.

For us, this coffee machine has long transcended its function as an household appliance. It is a warm symbol and an anchor point for a family. In its own way, it participates in and shapes our lives. It witnessed the father’s concentration, the mother’s meticulousness and the child’s growth. It connects every ordinary day with its fragrance, and together the sounds of grinding, extraction and our laughter, it composes a concerto named “Home”.

There are countless flavors of home. In our hearts, the most profound and irreplaceable thing is the rich and warm aroma of coffee that began with this coffee machine. What it brews is not just a drink, but the happy times we spent together.

This is not merely a production method, but also an immersive sensory experience. Now, let’s embark on this adventure to explore the origin of flavors.

Act One: Get to Know Your Stage – Components of the Hand-Press Coffee Machine
Before we start, let’s get to know each component of the hand coffee press as if it were an old friend

The main body of the fuselage: It is usually cylindrical and contains a piston pressure system inside.

Pressure rod: The core component that provides pressure, driving water to pass through the coffee grounds by pressing down.

Coffee powder bowl and filter basket: Containers for holding coffee powder, usually equipped with filter paper or a metal filter screen.

Brewing head: The place where hot water and coffee powder mix.

Base/coffee cup holder: A platform that supports the body and holds coffee cups.

Core principle: By manually pressing down the pressure rod, pressure (usually up to 5-9 bar) is generated in a closed space, forcing hot water to evenly penetrate the coffee powder cake in a short time and efficiently extract the oil and flavor substances within.

Act Two: Preparations – The Beginning of the Sense of Ceremony
Step One: Grind the coffee beans
This is the first step that determines success or failure. For hand-press coffee machines, we recommend medium to fine grinding, with a granular texture similar to that of white granulated sugar. Grinding too coarsely can lead to insufficient pressure, causing the coffee liquid to flow too fast and resulting in a sour and insipid taste. Grinding the details will make the pressing extremely difficult and it is easy to over-extract, resulting in a bitter taste.

Step Two: Preheat the machine
This is a step that is easily overlooked but of vital importance. Thoroughly rinse all components of the machine with hot water, especially the brewing head and the powder bowl. This can prevent the machine from absorbing the heat of the coffee powder cake during extraction and ensure a stable extraction water temperature.

Step 3: Weigh and powder
Use an electronic scale to weigh 15 to 18 grams of coffee grounds (corresponding to single or double espresso). Pour the coffee powder into the powder bowl and gently shake it left and right to evenly distribute it. Never slap hard.

Step Four: Evenly fill and press
Use a powder press, perpendicular to the surface of the powder bowl, and apply pressure steadily and evenly downward with the strength of your wrist. Make sure the surface of the powder compact is smooth and flat, without any tilt. Just press it flat in one go; there’s no need to press it repeatedly.

Act Three: The Art of Extraction – The Critical Moment of Pressing Mellow Aroma
Step 5: Water injection and assembly
Pour hot water at 90-96°C into the main body of the machine to the designated mark. Then, tighten the filter basket assembly containing coffee powder onto the machine body. Please complete the entire process as quickly as possible to minimize heat loss.

Step 6: Press down steadily and feel patiently
Place the machine above the coffee cup. Hold the machine body steadily with one hand and grasp the pressure rod with the other.

Initial stage: Gently and slowly press down about 1-2 centimeters to allow the hot water to fully soak all the coffee grounds. This process is called “pre-soaking” and lasts for about 5-10 seconds.

The main stage: After that, start to press down the pressure rod with a steady and uniform speed and force. The ideal downward pressing process should last for 20 to 30 seconds, ultimately resulting in approximately 30 to 45 milliliters of espresso.

Listening and Feeling: During the downward pressure process, you will hear a slight “hissing” sound, which is a sign that the pressure is being established. The resistance you feel in your arm should be continuous and firm. If the downward pressure is too easy, it indicates that the grinding degree is too coarse. If it is extremely laborious, it indicates that the grinding degree may be too fine.

Act Four: Cleaning and Maintenance – For the Next Perfect Encounter
After extraction is complete, please immediately knock out the coffee powder cake and rinse all components with hot water. Thorough cleaning not only ensures the service life of the machine, but also prevents residual coffee oil (which can deteriorate and spoil) from contaminating the flavor of your next cup of coffee.
