The coffee extracted by "Philharmonic pressure" has pure liquid and high concentration.

AeroPress is a new coffee making appliance launched by AEROBIE in 2006. Its inventor, Alan Adler, is a lecturer in mechanical engineering at Stanford University in the United States. It has more than 40 patents in the United States and other countries. "

"Love pressure" is easy to use. Put coffee particles in the pressure bucket, soak in water for 10 seconds, then gently press down the pressure bar in 20 seconds for a total of only 30 seconds. a cup of coffee with a delicate, rich, supple and delicious taste is made, unlike a dripping 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 pressure bar 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 higher, thus ensuring that the coffee drink is almost free of coffee powder. It uses the extraction method of an Italian espresso machine, but a layer of filter paper is added to the powder bowl, resulting in lower water temperature and lower pressure, resulting in a simpler structure and a much lower cost. but the extracted coffee tastes richer and softer without bitterness.
