All the knowledge of drip coffee

The rise of the boutique coffee market has undoubtedly led the public's attention to shift to a more diversified way of brewing coffee. Among them, the most important thing that can not be ignored is trickling coffee, which appeared at the beginning of coffee culture.

Speaking of which,

Babies must have a lot of questions.

What is dripping coffee?

Are all hand-brewed coffee filtered?

Does Philharmonic pressure belong to drip coffee?

Don't worry, and let the editor speak slowly.

Drip coffee

(the gift of natural gravity)

Pour water into a filter containing ground coffee powder, extract oil and aromatic substances, and under the action of gravity, the liquid flows slowly through the filter, while the coffee residue is left in the coffee brewing process in the filter. What distinguishes drip coffee from Italian coffee is that the process of water passing through coffee powder is only caused by gravity, and there is no artificial increase in external force.

The housewife opened and hung up and rewrote the filter history.

In the 19th century, people used to make coffee in three ways:

① 's most traditional immersion brewing is that the coffee powder is mixed with water, and the coffee liquid is poured out or drunk directly after sitting. The coffee made by this method contains more fine coffee powder, which will not only form an astringent feeling in the mouth, but also plug in the teeth and is not easy to clean.

② from 1810 to 1814, British-American Sir Thompson Benjamin (Benjamin Thompson) jointly developed an electric coffee maker (Percolator) with Count Rumford and an American scientist, which recycled hot water to brew coffee pressed powder. Because the water in the pot was constantly heated, extracted, and cooled, the coffee was extremely bitter after being over-extracted. Although the disadvantages of the three methods are obvious, under the conditions of science and technology at that time, people can only use this method all the time.

③ uses cloth bags to filter coffee grounds, although this method avoids the main shortcomings of soaking, but it is tedious to clean, and after many times of use, the residue left in the gap in the cloth bag will also affect the flavor of coffee.

It was not until 1908 that a German housewife, Melitta Bentz, had a whim to drill a hole under the copper pot, put on the children's blotting paper, poured in the coffee powder to filter, and invented the prototype of today's trickling filter cup. In the same year, she applied for a patent and founded Melita Company, whose main single-hole filter cup was also very popular and was affectionately known as the "Melita Cup". Today, the century-old Melita company is run by its grandchildren, and its business has expanded to sell filter paper, coffee and coffee utensils.

Due to the single-hole design of the "Merita Cup", the flow rate of coffee powder is slow when filtering. Therefore, this device is very suitable for medium-deep roasting and coarse coffee grinding. Therefore, this pure manual bubble method quickly took root in the oriental land, such as Japan, China, Taiwan and other places. In the history of coffee highlighted by male chauvinism, Benz Melita's invention undoubtedly adds color to this chapter.

The first dripping coffee machine

Wigomat

In 1954, the German Gottlob Widmann also invented the world's first electric coffee drip filter Wigomat, and applied for a patent. By the 1970s, all kinds of trickling filtration machines based on Wigomat principle gradually appeared on the market, but Wigomat was still very popular. The typical advantage of filter paper type drip filter cup is that it is convenient to clean, while the electric coffee drip filter has obviously improved in controlling water temperature. The advent of both undoubtedly accelerated the decline of the electric coffee maker after solving its disadvantages. And decline is bound to be accompanied by a new birth, and the development of drip coffee has so far given rise to more diversified ways.
