Do you know what is the most expensive coffee?

Speaking of the world's most expensive coffee, it has an inelegant-sounding name-Kopi Luwak (Kopi Luwak). Its price is several times more than the top Jamaican Blue Mountain coffee, at the same time, Kopi Luwak is also the world's least produced coffee, can be said to be the king of coffee, one of the world's top luxury goods.

This kind of coffee comes from the Indonesian island of Sumatra, where coffee trees grow for a long time. There is a local civet named Luwak, which likes to eat pulpy coffee fruit. And Luwak is a natural expert at choosing coffee fruits.

They are used to foraging at night, with a keen sense of smell, looking for those jujube mature coffee fruits to eat, other immature never eat, so the coffee beans excreted by it are all selected products. The coffee fruit that is eaten goes through the digestive system of Luwak, only the pulp on the outside of the fruit is digested, and the hard coffee beans cannot be digested, so they are excreted with the feces. After Luwak digestion and fermentation, some proteins in coffee beans are broken down into small molecules, which enhances the aroma of coffee during grinding. In addition, it can filter out some specific proteins, thus reducing the bitterness of the coffee.
