Kopi luwak

The origin of kopi luwak is closely connected to the history of coffee production in Indonesia; Dutch colonialists established coffee plantations in Indonesia and imported beans from Yemen. In the 19th century, farmers in central Java started to brew and drink coffee from excreted beans collected at their plantations. == Production ==

Kopi luwak is brewed from coffee beans that traversed the gastrointestinal tract of an Asian palm civet, and were thus subjected to a combination of acidic, enzymatic, and fermentation treatment. During digestion, digestive enzymes and gastric juices permeate through the endocarp of coffee cherries and break down storage proteins, yielding shorter peptides. This alters the composition of amino acids and impacts the aroma of the coffee. In the roasting process, the proteins undergo a non-enzymatic Maillard reaction. The palm civet is thought to select the ripest and most flawless coffee cherries. This selection influences the flavour of the coffee, as does the digestive process. The beans begin to germinate by malting, which reduces their bitterness. When performed in nature, or in the wild, these two mechanisms achieve the same goal as selective picking and the wet or washed process of coffee milling: 1) harvesting optimally ripe cherries and 2) mechanically and chemically removing the pulp and skin from the cherry, leaving mainly the seed. Traditionally, excreted coffee beans were collected directly in plantations and forests. As the international demand for kopi luwak increased, some producers turned to caged production methods to increase yields. It is produced in Indonesia, East Timor, the Philippines, Thailand, Vietnam and Ethiopia. == Taste ==

The taste of kopi luwak varies with the type and origin of the excreted beans, processing, roasting, aging, and brewing. The ability of the civet to select its berries, and other aspects of the civet's diet and health, like stress levels, may also influence the processing and, hence taste. Within the coffee industry, kopi luwak is widely regarded as a gimmick or novelty item. The Specialty Coffee Association of America (SCAA) states that there is a "general consensus within the industry...it just tastes bad". A coffee professional compared the same beans with and without the kopi luwak process using a rigorous coffee cupping evaluation. He concluded: "It was apparent that luwak coffee sold for the story, not superior quality...Using the SCAA cupping scale, the luwak scored two points below the lowest of the other three coffees. It would appear that the luwak processing diminishes good acidity and flavor and adds smoothness to the body, which is what many people seem to note as a positive to the coffee." Professional coffee tasters were able to distinguish kopi luwak from other coffee samples, but remarked that it tasted "thin". Some critics claim more generally that kopi luwak is simply bad coffee, purchased for novelty rather than taste. A food writer reviewed kopi luwak available to American consumers and concluded, "It tasted just like...Folgers. Stale. Lifeless. Petrified dinosaur droppings steeped in bathtub water. I couldn't finish it." A comparative chemical study revealed that civet-processed Robusta beans contained significantly higher total fat elevated levels of caprylic methyl ester and capric acid methyl ester; these compounds are commonly used as flavouring agents and are associated with creamy, dairy-like notes. == Imitation ==

Several commercial processes attempt to replicate the digestive process of the civets without animal involvement. Researchers with the University of Florida have been issued with a patent for one such process. Brooklyn-based food startup Afineur has also developed a patented fermentation technology that reproduces some of the taste aspects of Kopi Luwak while improving coffee bean taste and nutritional profile. Vietnamese companies sell an imitation kopi luwak, made using an enzyme soak which they claim replicates the civet's digestive process. Imitation has several motivations. The high price of kopi luwak drives the search for a way to produce kopi luwak in large quantities. Kopi luwak production involves a great deal of labour, whether farmed or wild-gathered. The small production quantity and the labor involved in production contribute to the coffee's high cost. Imitation may be a response to the decrease in the civet population. == Animal welfare ==

Growing numbers of intensive civet "farms" have been established and are operated in Southeast Asia, confining tens of thousands of animals to live in battery cages and be force-fed. "The conditions are awful, much like battery chickens", said Chris Shepherd, deputy regional director of TRAFFIC in Southeast Asia. "The civets are taken from the wild and have to endure horrific conditions. They fight to stay together, but they are separated and have to bear a very poor diet in very small cages. There is a high mortality rate, and for some species of civet, there's a real conservation risk. It is spiraling out of control". == Price and availability ==

Kopi luwak is one of the most expensive coffees in the world, selling for between in 2010. The price paid to collectors in the Philippines is closer to US$20 per kilogram. Most customers are Asian, especially those originating from Japan, China, and South Korea. Some specialty coffee shops sell cups of brewed kopi luwak for US$35–80. ==Authenticity and fraud==

Investigations by PETA and the BBC found fraud to be rife in the kopi luwak industry, with producers willing to label coffee from caged civets with a "wild sourced" or similar label. Genuine kopi luwak from wild civets is difficult to purchase in Indonesia and proving it is not fake is very difficult – there is little enforcement regarding use of the name "kopi luwak", and there's even a local cheap coffee brand named "Luwak", which costs under US$3 per kilogram but is occasionally sold online under the guise of real kopi luwak == Variations ==

Coffee beans can be "seeded" with the same microbes as in civet gut to produce the same coffee flavor without having to deal with civet excrement. There are reports of a kopi luwak type process occurring naturally with muntjac and birds. Bat coffee is another variation that is in demand. Bats feed on the ripest coffee and fruits and spit out the seeds. These seeds are dried and processed to make coffee with a slight fruity flavor. ==In popular culture==

In the movie The Bucket List, billionaire health care magnate Edward Cole (played by Jack Nicholson) brings kopi luwak with him on all of his travels but is unaware of how the drink is produced. Carter Chambers (Morgan Freeman) explains how civets defecate kopi luwak coffee beans, and that the gastric juices of the defecated beans give kopi luwak its unique aroma. The Japanese manga series Beastars features an anthropomorphic civet character named Deshico that produces kopi luwak. == See also ==
