Which country is known for producing a distinctive coffee variety called Kopi Luwak?

Kopi Luwak is a unique coffee variety that originates from Indonesia, making it well-known for its distinctive production method. The process involves coffee cherries being eaten and subsequently excreted by a civet, a small mammal native to the region. This process is believed to enhance the flavor profile of the beans due to the fermentation that occurs in the civet's digestive system. The beans are then collected, cleaned, and processed, resulting in a coffee that is often described as smooth with a rich flavor and low acidity. This unique method of production and the rarity of the beans contribute to Kopi Luwak's status as one of the most expensive coffees in the world, further highlighting Indonesia as the country associated with this remarkable coffee.
