As a coffee lover, you must know charcoal coffee. Authentic charcoal coffee is usually baked with charcoal fire depth, black color, taste mellow, adding refining milk will have a other flavor. Today, one way degassing valve to share with you is not charcoal coffee, but carbon coffee.
It is said that carbon coffee is a cafe in the 60s of last century for the conditioning of the gastrointestinal and invented, when the cafe owner as usual bake coffee, eyes staring at burning coal, suddenly a chance, took a hot carbon put into coffee. The cafe owner tried it and felt the taste of the coffee was so good, so he pushed out highly, slowly the coffee was well known locally. The cafe owner began to improve the taste of coffee. He grinds the ordinary coffee, added four tablespoons of sugar and boiled water, and puts a piece of red charcoal into the coffee cup until the charcoal cools and then took it out.
Some people have analyzed the carbon coffee, found that carbon absorbed a part of caffeine, but also in a certain sour, burning red carbon also burned some of the sugar in the coffee, making carbon coffee taste unique.
Now, if you travel to Yogyakarta in Indonesia, you can try the carbon coffee there. The price of this coffee is 4,000 rupees, equivalent to RMB 2.07 yuan. I believe that so cheap and soothing coffee, you will never miss it.
