How Kopi Luwak Coffee Is Made: Process and Facts

Ever wondered how coffee beans that pass through an animal’s digestive system end up being sold for hundreds of dollars per pound? Kopi Luwak—also known as civet coffee or colloquially as “cat poop coffee”—is one of the most expensive and controversial coffees in the world. Originating in Indonesia, this coffee is famous not just for its price, but for how it’s made: inside the stomach of a civet.

Kopi Luwak is made from coffee beans that have been eaten, fermented in the civet’s digestive tract, and excreted. The beans are then collected, cleaned, and roasted. The entire process, from ingestion to cup, involves multiple steps that contribute to its unique flavor—but also raise serious ethical and quality concerns.

What Is Kopi Luwak?

Kopi Luwak, or civet coffee, is a type of coffee produced from beans that have passed through the digestive system of the Asian palm civet, locally called luwak in Indonesia. These beans are eaten as part of the civet’s natural diet when it consumes ripe coffee cherries. The animal’s digestive enzymes partially break down the coffee fruit but leave the inner bean intact. The beans are then excreted, collected, cleaned, and roasted.

How Civet Coffee Is Made: Step-by-Step

The traditional production of Kopi Luwak follows a multi-stage process:

1. Civets selectively eat ripe, red coffee cherries.
2. The beans inside the cherries pass through the civet’s digestive tract, where gastric acids and enzymes ferment the beans, breaking down proteins.
3. The beans are excreted in the civet’s feces, still encased in a silver skin.
4. Workers manually collect and sort the feces to extract the undigested beans.
5. The beans are washed to remove any remaining waste material.
6. The beans are dried in the sun.
7. The outer silver skin is removed.
8. The beans are roasted to become drinkable coffee.

This unique fermentation process inside the civet’s gut is said to reduce bitterness and develop a smoother, richer cup profile. However, nearly all of these steps happen outside human control when the beans are collected from wild animals.

The Science Behind the Flavor

The key to Kopi Luwak’s distinctive taste lies in the partial digestion of the coffee bean. Enzymes in the civet’s stomach break down proteins in the bean, which are one of the main sources of bitterness in regular coffee. This leads to a cup that tasters often describe as smoother, less acidic, and more syrupy. According to coffee expert Chris Rubin, the brew has a “rich, syrupy thickness” with a “chocolatey” profile and a long, clean finish. Others, however, compare it to “bathwater with petrified dinosaur droppings.”

Controversies and Ethical Issues

While wild civets naturally select the ripest beans, the high demand for Kopi Luwak has led to widespread unethical practices. Most of the Kopi Luwak sold today comes from caged civets, often kept in filthy, cramped conditions and force-fed a diet of coffee cherries. These animals frequently suffer injuries, disease, and early death. Additionally, it’s estimated that up to 85% of Kopi Luwak on the market is fake, with regular coffee falsely labeled as civet coffee to command premium prices.

Beyond animal welfare, the flavor benefits of wild civet digestion are largely lost in factory farming scenarios. The beans from caged civets are considered inferior, both ethically and in cup quality.

Production Facts and Rarity

It takes roughly 150 grams of beans to be harvested from one kilogram of civet droppings. During roasting, another 20% of those beans are typically lost. This makes the yield extremely low. Global annual production of genuine Kopi Luwak is estimated to be no more than 400 kilograms. Each 50-gram pack can cost over 800 RMB (approximately $100 USD), yielding just 4–5 cups of coffee. At that rate, a single cup can cost around 200 RMB (about $30 USD).

In 2010, during the Shanghai Expo, a 12-gram cup of Kopi Luwak from the Bohor Coffee Group was sold for 380 RMB. In the UK, a single cup may go for £50. In the U.S., prices for a kilogram of beans can reach $1,200, with the global market price typically hovering near $1,000.

How to Brew Kopi Luwak

To brew Kopi Luwak, experts recommend avoiding milk or sugar to fully experience its unique profile. A siphon (vacuum pot) is the preferred brewing method:

• Use 17 grams (about 2 scoops) of Kopi Luwak coffee grounds.
• Add 160–180 ml of pure water.
• Heat water to 96°C.
• Set the siphon to a pressure of 9–10 atm.
• Allow the coffee to brew for 1 minute and 45 seconds to 2 minutes.
• Cool the lower chamber quickly with a damp cloth to stop extraction.

The coffee should produce a rich layer of golden crema. Due to its intense processing, it is not recommended to rebrew the grounds.

Frequently Asked Questions

What is Kopi Luwak coffee?

Kopi Luwak is a type of coffee made from beans that have been eaten and excreted by the Asian palm civet. The beans ferment in the civet’s digestive system, which is believed to change their flavor profile. The beans are then collected, cleaned, and roasted for consumption.

Why is Kopi Luwak so expensive?

Kopi Luwak is expensive due to its rarity, labor-intensive production process, and the limited number of beans that can be harvested from civet droppings. Only about 150 grams of usable beans are collected per kilogram of feces, and annual global production is under 400 kilograms.

Is Kopi Luwak coffee safe to drink?

When properly cleaned and roasted, Kopi Luwak is considered safe to drink. However, concerns about hygiene and ethics, especially regarding the treatment of captive civets, have led to widespread controversy and skepticism about its production.

Does civet coffee really taste better?

Opinions vary widely. Some experts describe Kopi Luwak as smooth, syrupy, and low in bitterness with chocolatey notes. Others find it unpleasant, comparing it to dirty water or rotting matter. Much of the positive reputation is attributed to its unique backstory rather than universally agreed-upon flavor quality.

Is wild civet coffee better than farmed?

Yes. Wild civets selectively eat ripe coffee cherries, contributing to better flavor and ethical production. Farmed civets are often force-fed and kept in poor conditions, and their beans are generally of lower quality and considered less authentic.

How is Kopi Luwak processed after collection?

After collection from civet feces, the beans are washed, the outer silver skin is removed, and the beans are sun-dried. Once dried, the beans are roasted using standard coffee roasting methods before being brewed like other specialty coffees.
