It was invented by Alan Adler, a lecturer in mechanical engineering, who holds more than 40 patents in the United States and other countries. He is also a lecturer, electrical engineer, amateur physicist and toy enthusiast at Stanford University in the United States. As he was not satisfied with the coffee made at home, he began to look for a new way to make it. He identified the factors that affect the taste of coffee, such as time, temperature, and grinding, and developed a simple device to coordinate these factors. Since then, the Philharmonic pressure coffee was born!

The principle and usage of Philharmonic pressure coffee is very simple: a hard plastic tube, a filter cover, a rubber seal plug. The basic kit also includes a blender, a spoon and filter paper for a year, and a funnel to pour Philharmonic-pressed coffee bean powder into a plastic tube.

Overall, its structure is similar to that of a syringe. When in use, put ground coffee and hot water in its "syringe", then press the putter, and the coffee will flow into the container through the filter paper. It combines the immersion quenching method of the French filter pressure pot, the filter paper filtration of the follicular coffee, and the fast, pressure quenching principle of Italian coffee.

The brewed coffee has the richness of espresso, the purity of brewed coffee and the smooth taste of a French filter pot. By changing the size and pressing speed of coffee grinding particles, you can cook different flavors according to your own preferences.

Unlike the drip filter coffee machine, although the soaking time is very short, it can fully soak the coffee particles and exert soothing and gentle pressure during extraction. It draws lessons from the principle of the French press, but the coffee liquid is pressed out from the bottom of the apparatus through the filter paper, and the coffee particles are finer than those required by the French press, and the contact time between coffee and water is shorter but the pressure is greater, thus ensuring that the coffee drink is richer and softer without a hint of bitterness.

In addition to being fast, convenient and effective, its cleaning and maintenance method is surprisingly simple, and the cleaning time after use is only a few seconds. And it also has the advantages of short size, light weight and not easy to damage, so it is quite suitable to be used as a coffee brewing apparatus for going out.

The steps of making coffee beans under the pressure of Philharmonic:

Put the Philharmonic pressure special filter paper into the filter paper cover and wet the filter paper to better fit the cover.

Place the filter paper cover on the filter cartridge and stand on the sturdy cup

Grind the coffee bean powder with two special spoons into the filter cartridge.

Slowly pour 80 degrees hot water into the filter cartridge to scale 2

Stir gently for about 10 seconds

Wet rubber seal plug, insert the pressure rod into the filter cartridge and press it down gently for about 20s

One double espresso.

Can be made into American coffee (add hot water) and latte (add hot milk) according to your personal preference.

The cleaning process of Philharmonic Coffee is extremely simple, and the filter paper can even be reused 5 to 6 times. Take apart the Philharmonic, put it under the faucet and rinse directly. The whole process is only 20 seconds.
