Kopi luwak, or civet coffee, is one of the world’s most expensive and low-production varieties of coffee. It is made from the beans of coffee berries which have been eaten by the Asian Palm Civet, then passed through its digestive tract. A civet eats the berries for their fleshy pulp. In its stomach, enzymes seep into the beans, making shorter peptides and more free amino acids. Passing through a civet’s intestines the beans are then defecated, keeping their shape. After gathering, thorough washing, sun drying, light roasting and brewing, these beans yield an aromatic coffee with much less bitterness, widely noted as the most expensive coffee in the world.
Since the flavor of coffee owes much to its proteins, there is a hypothesis that this shift in the numbers and kinds of proteins in beans after being swallowed by civets brings forth their unique flavor. The proteins are also involved in non-enzymatic Maillard browning reactions brought about later by roasting. Moreover, while inside a civet the beans begin to germinate by malting which also lowers their bitterness. Kopi luwak is produced mainly on the islands of Sumatra, Java, Bali and Sulawesi in the Indonesian Archipelago, and also in the Philippines, and also in East Timor. Weasel coffee is a loose English translation of its name cà phê Chồn in Vietnam, where popular, chemically simulated versions are also produced.
The origin of Kopi Luwak is closely connected with the history of Coffee production in Indonesia. In early 18th century The Dutch established the cash-crop plantations in their colony in Dutch East Indies islands of Java and Sumatra, including Arabica coffee introduced from Yemen. During the era of Cultuurstelsel (1830—1870), the Dutch prohibited the native farmers and plantation workers to pick coffee fruits for their own use. Yet the native farmers desired to have a taste of the famed coffee beverage. Soon the natives learned that certain species of musang or luwak (Asian Palm Civet) consumed these coffee fruits, yet they left the coffee seeds undigested in their droppings. The natives collect these Luwak’s dropping coffee seeds; clean, roast and grind it to make coffee beverage.
Kopi luwak is a name for many specific cultivars and blends of arabica, robusta, liberica, excelsa or other beans eaten by civets, hence the taste can vary greatly. Nonetheless, kopi luwak coffees have a shared aroma profile and flavor characteristics, along with their lack of bitterness. Kopi luwak tastes unlike heavy roasted coffees, since roasting levels range only from cinnamon color to medium, with little or no caramelization of sugars within the beans as happens with heavy roasting. Moreover, kopi luwaks which have very smooth profiles are most often given a lighter roast. Iced kopi luwak brews may bring out some flavors not found in other coffees.
