Qianjie-introduction to the production of cold extract coffee

The earliest documented cold-extracted coffee originated in the Netherlands. In the 17th century, the Netherlands became very powerful at sea, with the best crew and shipbuilding skills in the world, even surpassing the status of maritime overlord England. At that time, Dutch colonists dominated world trade for a long time.

In order to solve the problem that the crew sailed for a long time on the sea to drink coffee, they invented a strange way of brewing: after soaking the coffee powder in cold water for more than 20 hours, the taste of the coffee was extracted, and in this way the concentrated original solution of coffee was produced. The original solution contains more caffeine, and the taste is good. It does not need to be heated, and the shelf life can be extended. It is greatly convenient for the seafarers and businessmen at sea.

At that time, the people on board still liked to boil the extracted solution with water and drink it, but sometimes they drank the original solution directly for convenience. As a result of the repeated expansion of colonial hegemony, the Netherlands established the East India Company, which is the first multinational company in history. The company has long monopolized Asian trade, taking the easternmost side of the trade to Japan, and this method of making coffee was introduced to Japan.

While Japan has a tradition of making cold tea since ancient times, this method of cold brewing coffee does not seem to be new when it comes to a new place. The Japanese invented Kyoto-drip method of coffee brewing in combination with their own way of making cold tea. Now some minority cafes still use Kyoto-drip method to make cold extracted coffee, which has become one of the items that coffee lovers must experience.

Cold coffee is suitable for personal taste preference, and the way of making it is relatively broad.
