Luwak coffee is known as the rarest and most expensive coffee in the world. It is definitely unique and only available in very limited quantities from plantations on the isles of Java, Sumatra and Sulawesi along the Indonesian Archipelago. The coffee is so unique because the beans pass through the digestive tract of the Luwak cat (Civet) which lives naturally in the forests surrounding the coffee plantations. What makes Kopi Luwak so special is the selection of the ripest cherries by the civet and the natural fermentation of the beans during the digestive process. Enzymes act on the beans to soften the acidity and reduce the earthy tones while building the body and the deep unique flavor of the coffee beans.
