Genuine Wild Luwak Coffee Arabica Aceh Gayo is arabica coffee harvested from the feces of civet animals that live in the wild. Civets are known to have a very keen sense of smell, so they only eat ripe coffee cherries. The coffee undergoes fermentation in the civet's stomach, as the civet only takes in the sweet glucose and the beans are not destroyed in its digestive system. The beans come out with the civet's feces and it takes patience to collect them and this is one of the reasons why civet coffee is expensive.
