6th century AD: Gela people chew coffee fruit and kate grass.
9th to 11th centuries: Persian physicians used coffee as medicine.
1400-1470: Coffee godfathers Chadilli and Dabbani promote "Kash" and kava beverages. At this time people were still brewing the coffee pulp and even discarding the coffee core (bean).
A hot drink called "kax" has suddenly become popular in the ports of Mocha and Aden in Yemen. This kind of drink is to pick the red coffee fruit, use only the pulp part after drying, and discard the coffee beans in it, and then put the dried coffee pulp into a ceramic plate, roast it with a slow fire, mash it, and then use it with Boil in hot water and drink hot. The pulp still contains 1% caffeine, it also has a refreshing effect, and the flavor is far sweeter and delicious than chewing on the coffee fruit leaves, and soon spread throughout the Arabian Peninsula.
Later started to fry with fire (coffee beans and pulp together).
The earliest coffee roasting may have been that Ethiopian or Yemenis inadvertently used coffee branches and leaves to make a fire. They found that the aroma of roasted coffee fruit was fascinating, so they buried the "fire" of roasted coffee.
In Syria in 1500, due to the development of metallurgical technology, people invented the roasting technology and added the grinding process, and finally it was possible to grind beans.
The hand-cranked bean grinder was invented, but the precision is not high, and it can only be coarsely ground.
So in the 16th century Turkey, people separated coffee grounds and coffee for the first time. At first it was through gauze (flannel). But the problem with flannel is obvious: Because of the grease in the coffee, the grease can stay on the gauze, and after repeated use, the gauze will smell bad.
In Vienna in the 17th century, coffee was first drunk with milk and served with croissants.
In 1906, Ms. Merita Banz of Germany made the world's first hand-washing filter cup with ink-absorbing paper, and this model is still in use today.
Later, with the development of science and technology, in Italy, engineers invented a way to quickly extract coffee, which is our current "espresso".
Americano was made by Europeans adding water to espresso in order to sell coffee to Americans.
The concept of specialty coffee was proposed by Onam, the "mother of specialty coffee" in 1974.
