What Is Kopi Luwak and Why Is It So Controversial?

You’ve heard the rumors — coffee made from beans eaten and excreted by animals, said to be smooth, sweet, and worth a small fortune. But is it really that good? Or just a story wrapped around a very unusual farming practice? This is the reality behind Kopi Luwak, the controversial ‘cat poop coffee’ that has fascinated and horrified coffee lovers worldwide for decades.

Kopi Luwak is made from coffee beans eaten and passed through the digestive system of the Asian palm civet (locally called luwak or musang), mainly in Indonesia. The beans are then collected, cleaned, and roasted. While some claim exceptional sweetness and reduced bitterness, experts and industry bodies widely criticize its actual cup quality.

What Exactly Is Kopi Luwak?

Kopi Luwak, also known as civet coffee, originates from Indonesia. The name comes from the Indonesian word ‘kopi’ (coffee) and ‘luwak’ (a local term for the Asian palm civet, a small, tree-dwelling mammal). Also called musang in parts of Sumatra, this animal eats ripe coffee cherries, digests the fruit pulp, but cannot break down the hard coffee bean inside. The bean exits the civet’s digestive tract intact, having undergone unique fermentation inside the animal.

These excreted beans are collected, thoroughly washed, and processed using either washed or natural methods before roasting. The end product is a very limited quantity of coffee that, due to the unusual production process and scarcity, commands extremely high prices.

How Does Digestion Change the Coffee Beans?

When a civet eats coffee cherries, its stomach acids and enzymes partially ferment the beans. This process reportedly breaks down proteins in the bean, which are a major source of bitterness in normal coffee. The breakdown leads to an increase in free amino acids and shorter peptides. The result, according to some tasters, is a smoother, less bitter cup with a distinctive richness — often described as syrupy, chocolatey, and long-lasting on the palate.

The civet’s digestive system is believed to selectively consume only the ripest, sweetest coffee cherries, which could also influence the final flavor profile. However, this selection process is only possible with wild civets — behavior that changes when the animals are caged and fed cultivated beans.

The Controversy Around Civet Coffee

The specialty coffee industry has long been skeptical of Kopi Luwak. The Specialty Coffee Association of America (SCAA) has stated that “the consensus in the industry is that it tastes bad.” One SCAA expert commented that its appeal lies in the story, not cup quality. According to SCAA standards, Kopi Luwak often scores lower than other commercial coffees — sometimes two points below accepted minimums — due to muted acidity and flat flavor.

Prominent coffee writers have been equally critical. Tim Carman of The Washington Post described his experience with American-sold Kopi Luwak as reminiscent of “Folger’s coffee... like bathing in the water of a petrified dinosaur turd.” He couldn’t finish the cup.

Wild vs. Farmed Civet Coffee

Originally, Kopi Luwak was produced from beans collected in the wild, where civets freely chose the ripest coffee cherries. This natural selection was believed to enhance cup quality. However, due to high market demand and profitability, most Kopi Luwak today comes from caged civets fed a controlled diet of coffee cherries.

Farmed civets often suffer in poor conditions, and the beans they produce are considered inferior in flavor. The natural fermentation benefits are lost when civets can’t choose their fruit, and the beans lack the complexity associated with wild-foraged examples. Still, both versions remain extremely rare and expensive.

What Does Kopi Luwak Taste Like?

Coffee expert Christopher Rubin once described high-quality Kopi Luwak as having “rich and intense aroma, incredibly thick body, almost syrupy, with a chocolatey mouthfeel and a long, pure aftertaste.” Such descriptions match what some wild-collected examples have delivered — a low-acidity, smooth, and rounded cup.

However, these positive tasting notes are not consistent, especially among industrially produced or farmed Kopi Luwak. Most experts agree that its reputation far exceeds its actual sensory qualities.

Where Does Kopi Luwak Come From?

Kopi Luwak originates in Indonesia, particularly on the island of Sumatra, where the local name ‘kopi musang’ is used. The Asian palm civet is native to much of Southeast Asia, including India, Bangladesh, Nepal, Bhutan, and parts of China, but only the Sumatran and other Indonesian civets are associated with producing this coffee.

The beans are collected from civet droppings, cleaned, and processed using traditional methods. Originally, Indonesian farmers adopted the processing techniques — including washing and drying — from standard washed or natural coffee methods, but the initial fermentation occurs inside the animal.

Frequently Asked Questions

What is Kopi Luwak coffee?

Kopi Luwak, or civet coffee, is made from coffee beans that have been eaten and excreted by the Asian palm civet, a small mammal native to Southeast Asia. The beans ferment in the civet’s digestive system, which is said to alter their flavor profile, then are collected, cleaned, and roasted.

Why is Kopi Luwak so expensive?

Kopi Luwak is expensive due to the unusual production process, limited supply, and the labor-intensive collection of beans from civet feces. The rarity and the story behind it also contribute to its high market price.

Does civet coffee really taste better?

Many experts, including the SCAA, argue that Kopi Luwak does not taste better than other high-quality coffees. Some tasters report a smooth, low-acid cup, but blind tastings and professional evaluations often rate it poorly for lacking acidity, complexity, and desirable flavor traits.

Is wild civet coffee better than farmed?

Yes. Wild civets selectively eat ripe coffee cherries, which may improve flavor. Farmed civets are typically caged and fed a controlled diet, which results in less flavorful and lower-quality beans, despite still being marketed as Kopi Luwak.

How are the coffee beans collected?

Coffee beans are collected from the feces of civets. Workers clean the beans thoroughly to remove any contamination, then process them using standard coffee washing or natural drying methods before roasting.

Is Kopi Luwak still popular today?

Kopi Luwak remains a novelty in the coffee world. While it garners attention for its unique backstory, it is not favored by specialty coffee professionals and is generally avoided by serious coffee enthusiasts.
