The reason why coffee powder does not expand-coffee powder can be brewed directly

The name American coffee comes from the habit of American soldiers in Europe during the war to mix hot water with small espresso coffee common in Europe. It is said that the Apollo spacecraft, the first manned moon landing, had a life-and-death failure on its way home. At that time, the ground staff comforted the three astronauts with one sentence: Come on! A nice hot American coffee awaits you.

Because Americans tend to make coffee more casually and simply, this method quickly became popular with American chains around the world. Typically, a cup of American coffee consists of two espresso shots mixed with 30 to 470ml of hot water. Because of the large amount of hot water added, American coffee will appear weak in appearance and taste. In addition, the aroma of coffee will be slightly damaged, and it will not last as long as traditional Italian coffee. Despite dilution with hot water, American coffee is still higher in caffeine than regular coffee. However, its calories are very low.

In the United States, Australia, and new Zealand, blending with hot water followed by espresso is sometimes called Long Black. Sometimes, some simple coffee machines are also called American coffee machines. Actually they're drip coffee machines.

Bentz Melitta, a German housewife, is credited for this worldwide popularity of follicular coffee brewing. She invented the coffee follicle method more than 100 years ago, rewriting the history of coffee drinking in Germany and the world. Before this invention, people used cloth bags to filter coffee grounds. However, the cloth filter bag is troublesome to clean, and the other is unsanitary after repeated use. The coffee grounds remaining in the gap of the bag are easy to destroy the original taste of coffee. On June 20, 1908, Melita registered her invention at the Royal Patent Office: a copper coffee filter cup with an arched bottom perforated with a water outlet, which was the world's first follicular coffee cup. Melita Benz founded Melita Inc. in her residence on a small budget and registered her signature Melitta as a trademark.

Like siphon coffee, with the rise of fine coffee culture, hand-brewed coffee also ushered in a new spring. This ancient way of brewing coffee miraculously took root and blossomed in the eastern land, especially in Japan, South Korea, China Taiwan and inland areas. Especially since the 1950s, Japanese people have almost become obsessed with coffee brewing. Follicular and drip coffee filter cups of various materials emerge one after another. A complete set of hand-brewed follicular coffee theory and operation technology has been established, which has been loved by more and more people. It is really the proverb of "the west is not bright and the east is bright".

◆ This time we use HARIO V60 three-person sharing pot and filter cup to make coffee for two people. The usual ratio of powder to coffee solution is 1:12~15, that is, 10 grams of coffee powder produces 120~150ml of coffee solution (usually 100ml, 200ml, etc. are marked on the sharing pot).
