History[ edit ] The origin of kopi luwak is closely connected with the history of coffee production in Indonesia. In the early 18th century the Dutch established the cash-crop coffee plantations in their colony in the Dutch East Indies islands of Java and Sumatra, including Arabica coffee introduced from Yemen.

During the era of Cultuurstelsel —70the Dutch prohibited the native farmers and plantation workers from picking coffee fruits for their own use.

Still, the native farmers wanted to have a taste of the famed coffee beverage. Soon, the natives learned that certain species of musang or luwak Asian palm civet consumed the coffee fruits, yet they left the coffee seeds undigested in their droppings.

The natives collected these luwaks' coffee seed droppings, then cleaned, roasted and ground them to make their own coffee beverage. It digests the fruit and expels the beans, which our farm people collect, wash, and roast, a real delicacy.

Something about the natural fermentation that occurs in the luak's stomach seems to make the difference. For Javanese, this is the best of all coffees—our Kopi luak.

Luwak is a local name of the Asian palm civet in Sumatra.

Civets also eat small vertebrates, insects, ripe fruits and seeds. Selection occurs as the civets choose which cherries to eat — i. Digestive mechanisms may improve the flavor profile of the coffee beans that have been eaten.

The civet eats the cherries for the fleshy pulp, then in the digestive tract, fermentation occurs. The civet's protease enzymes seep into the beans, making shorter peptides and more free amino acids.

On farms, civets are either caged or allowed to roam within defined boundaries.

After spending about a day and a half in the civet's digestive tract the beans are then defecated in clumps, having kept their shape and still covered with some of the fleshy berry's inner layers.

Despite being in contact with faeces and pathogenic organisms, the beans contain negligible amounts of the enteric pathogenic organisms associated with feces.

Moreover, the "cherry" or endocarp surrounding the bean is not completely digested by the luwak, and after being collected, the farmer performs thorough washing and removes the endocarp. Sumatra is the world's largest regional producer of kopi luwak.

Sumatran civet coffee beans are mostly an early arabica variety cultivated in the Indonesian archipelago since the 17th century. Tagalog kape alamid comes from civets fed on a mixture of coffee beans and is sold in the Batangas region along with gift shops near airports in the Philippines.

Vietnam has two farms with wild civets in Dak Lak, while in Mindanao island of the Philippines, has two farms with in Davao City and Iligan City wild civets. But the archipelago of Indonesia where the famous kopi luwak was first discovered and produced is leading in supplying the world market for almost three centuries, where many small-scale civet farms are proliferating in the countryside.

Defecated luwak coffee berries, East Java Several studies have examined the process in which the animal's stomach acids and enzymes digest the beans' covering and ferment the beans. These secretions carry proteolytic enzymes which break down the beans' proteins, yielding shorter peptides and more free amino acids.

The proteins also undergo non-enzymatic Maillard browning reactions in the later roasting process.We're hoping to rely on our loyal readers rather than erratic ads. To support Open Culture's continued operation, please consider making a donation.

Rogers State University was the first university in Oklahoma – and one of the first in the nation – to offer bachelor’s and associate degrees entirely via the Internet. "Smith conceived of the process of increasing production as 'division of labor' into more and more steps, with each laborer specializing in a smaller slice of the process.
