So, do you, who often make coffee, know the origin of this trickle extraction? This article takes you to discuss the history of hand-brewed coffee and all kinds of classic filter cups.
The origin of the filter cup
For a long time, people around the world made coffee in a simple and rough way: grind the beans and boil them in a kettle, then sift the dregs with linen or metal strainer and drink them directly. Limited to the level of production technology at that time, the filter can not make enough fine pores, so even the filtered coffee liquid often contains a lot of dregs.

Until the 20th century, a German woman named Amalie Auguste Melitta Bentz liked to brew coffee, but she found the coffee with a traditional filter bitter and bitter, and the coffee grounds left between her teeth affected the taste. As a result, Ms. Melita began to try new ways to make coffee, hoping to solve the problem of filter residue, and finally came up with an idea:
Punch the bottom of a copper jar into a container similar to a sieve, then put a piece of blotting paper on it, put it into the ground coffee powder, pour it into hot water, and the coffee liquid drips into the copper pot through the blotting paper.

Compared with linen cloth and metal strainer, this combination designed by Melita can not only filter the residue, but also retain the aroma of coffee, which is not only low cost, but also easy to use. The most important thing is that the percolated coffee liquid is clear and slag-free, and the taste has been greatly improved.
The evolution of filter cup
In June 1908, Melita registered her invention with the Royal German Patent Office: a copper coffee filter and filter paper with a water outlet at the bottom, which may be the world's first follicular coffee cup. At the same time, she founded The Melitta Company and began officially selling hand-punching tools.

Since its establishment, Melita has repeatedly studied and optimized the shape, size, filter holes, grooves and other details of the filter cup to meet the changes of the coffee era and the needs of consumers. Hand coffee utensils continue to bring forth the new, designing a series of new products, such as the trapezoidal filter cup that we are familiar with today is the best-selling representative of Melita at that time.
During the birth of Melita filter cup, many new types of hand flushing instruments were introduced. For example, the Chemex coffee maker, developed and designed by chemist Peter Schlumbohm in 1941, is both good-looking and practical.

In addition, some hand flushing devices made in Japan are also very popular. Japan's Hario company was founded in 1921, the original production of thermal insulation glass products. Because the water hole of the popular Melitta filter cup at that time was small and the flow rate was too slow, the coffee powder extracted from the latter part was basically soaked. So the Hario designer changed the filter cup to a conical cup with an angle of 60 °. It makes the water flow to the center and prolongs the contact time between the water and the coffee powder. At the bottom is a large single hole design to make the water flow more smoothly.

The cake cup Kalita Wave filter cup is also invented in Japan and is characterized by a flat-bottomed structure with 3 or 4 small holes to make the powder bed thinner and inclined to immersion extraction. The direct contact area between the filter paper and the filter cup is the smallest, even if the water flow accidentally rushes onto the filter paper, it will pass through the coffee powder layer to reach the sewer hole.

The spread of hand-made coffee
Although hand-brewed coffee was born in Germany, due to more processes and time-consuming, Italian coffee machine was later born, emphasizing the rapid rise of coffee culture, this kind of pure handmade follicle coffee did not become popular in European countries at that time. And it is the Japanese who really make hand-made coffee popular.

Since the 1950s, Japanese opponents have been obsessed with making coffee. The coffee filter cup appliances of various materials emerge one after another, which not only establishes a whole set of theory and operation technology of hand-brewed coffee, but also makes hand-brewing rise again with the third wave of coffee, which is loved by more and more people. and bring unprecedented prosperity.
