What are the main nutrients of coffee beans?

Coffee was planted in large numbers by Arabs in the 12th and 3rd centuries, and the world's first coffee shop was born in Damascus in the Middle East in the 16th century (1530). In just a few years, there were different numbers of coffee shops in more than 200 cities throughout the empire, from the ancient Constantinople to the Caucasus, from the Persian Gulf to Budapest, and the roads connecting these cities across the desert wilderness were dotted with mobile coffee tents to serve a steady stream of business travelers and troops. Coffee also spread to Europe in the same century, when coffee was taken to western countries with the Turks on a western expedition to Austria. Unexpectedly, it soon captured the hearts of Europeans. According to records, a packet of samples sent from Venice to the Netherlands in 1596 was the earliest coffee bean seen by Europeans north of the Alps. Legend has it that coffee was so rare in Western Europe that at first there was a joke that German housewives used chicken soup to make coffee. According to scholars' speculation, in the booming import and export trade of seasoning raw materials at the end of the 16th century, many coffee beans from the east began to enter Europe through Venice with developed economy and trade.

However, it was not until 1683 that the first coffee shop in Europe was opened by a Polish in Vienna, Austria. Businessmen who are proficient in Eastern European and Turkish languages, led by the brilliant Armenian businessman Johannes Diodato, not only acted as translators and guides for Austria in wartime, but also engaged in the hugely profitable coffee trade on both sides of the line of fire, meeting the needs of their own cafes, while also solving the urgent shortage of raw materials for many aristocratic and wealthy citizens' family salons. Won the attention of the upper echelons. A few years later, the coffee industry, which can be seen everywhere in the streets and alleys, developed rapidly. Most of these cafes were opened by his fellow villagers or Turks from other parts of the Ottoman Turkish Empire, naturally with a strong Middle Eastern flavor. Many street corners float out of the coffee hot smell of the narrow shop, you can also see the Istanbul coffee shop unique wall bench, open firewood coffee stove Most of the guests come from vendors, craftsmen and craftsmen who make a living in a nearby market.

Today, people are familiar with, or imagine elegant, comfortable, pure European-style cafes with an open social salon atmosphere, will have to wait for about 50 years, until the Enlightenment era of the general awakening of civic consciousness. before it really began to take to the center of life in Vienna and other Western cities.

Technically, it's just a small, simple coffee shop. At that time, people in the middle and upper classes were still intoxicated in the closed private coffee circle in their homes, and the free citizen class, which was keen on the initial economic success, had not yet become a force to influence the social and political society.
