Kopi Luwak is an island that produces coffee fruit, but there is a kind of cat on the island that likes coffee fruit very much, so people kill cats, but they can't kill them clean. There are always coffee fruits eaten by cats. There was a coffee plantation owner who once did not collect enough coffee beans, so he found undigested coffee beans in the cat's droppings, collected them and washed them. Later, the man who collected the coffee beans told him that his coffee beans were of the best quality, and asked him how he planted them, saying that he would still collect the coffee beans. He later said that they were picked out from the cat's feces because they went through all the special chemical processes of the cat's digestion process. So Kopi Luwak became popular.

In Indonesia, Kopi Luwak is called Kopi Luwak,kopi, which means coffee, and luwak means civet. Kopi Luwak (kopi luwak) is a kind of kopi tahi. Tahi means excrement in Indonesian. Yes, it means Xiang. The essence of Xiang coffee (kopi tahi) lies in three points. 1. Feed animal coffee beans, coffee beans through the digestive tract, will react with stomach acid and protease. Proteins and other substances that cause bitterness in coffee beans are partially digested. two。 The coffee beans stayed in the stomach and intestines for more than ten hours, the warmth and moisture began to germinate, and the flavor of the coffee beans changed. 3. Wild animals will choose mature and delicious coffee beans to eat. According to this principle, it is not so important what kind of animal is used to produce coffee beans. As long as coffee beans are metabolized in the body for a long time, digestive juices are suitable, and feces are pure and easy to collect, why stick to Maoxiang? all kinds of taste can impact your taste. As a result, there is coffee like shit.

People who enjoy the most expensive coffee in the world will soon be able to sip coffee without having to worry: researchers have devised a way to tell these people whether the coffee they buy is real or fake.

The luxury drink in question, Kopi Luwak (Kopi Luwak), is named after the Indonesian word for coffee and the Asian civet (coconut cat), a cat-like animal involved in the production of coffee.

After the civet eats the ripe fruit of the coffee plant (pictured), it digests the outer pulp and then excretes the whole coffee beans. the feces are collected, washed (thankfully), fermented, dried and roasted-a time-consuming process that ends up costing the drink about $330 to $500 per kilogram.

Such a profitable product is bound to have a lot of counterfeiters, indeed, the market is full of fakes. So in a new study, the researchers used chemical analysis to study four different coffee mixtures: real Kopi Luwak, regular coffee, and the 1:1 mixture of both. And other textured coffee beans-producers have treated these beans chemically, trying to simulate mammalian excrement.

Coffee contains hundreds of natural organic compounds, a small part of which enabled the team to distinguish Kopi Luwak from other coffees. The researchers published the report in the Journal of Agricultural and Food Chemistry. In particular, Kopi Luwak contains higher concentrations of malic acid and citric acid, as well as a higher ratio of cellulose to pyroglutamic acid.

While trained experts and odor detector "electronic noses" can also distinguish real Kopi Luwak from other coffee, the study clearly identified chemicals that show real coffee bean properties for the first time, the researchers said. In addition, the technology even feels sensitive enough to distinguish pure Kopi Luwak from coffee mixed with different percentages of other coffee impurities-which is somewhat reassuring when you enjoy a $15 cup of coffee in the morning.
