What Is Kopi Luwak Coffee and How Is It Made?

If you’ve ever heard someone joke about drinking ‘cat poop coffee,’ they were talking about Kopi Luwak—the world’s most infamous (and expensive) coffee. But behind the bizarre name lies a real agricultural oddity: coffee beans that have passed through the digestive system of a wild or captive animal. The big questions are: What actually makes it different? Is it worth the hype? And how on earth is it made?

Kopi Luwak is made from coffee beans eaten and excreted by the Asian palm civet—also called a luwak. These beans are then collected, cleaned, and roasted. The key difference comes from partial fermentation inside the civet’s digestive tract, which alters protein structures and reduces bitterness. But most ‘Kopi Luwak’ on the market today isn’t made this way at all.

What Exactly Is Kopi Luwak?

Kopi Luwak, also known as civet coffee or cat poop coffee, originates in Indonesia. The name comes from the Indonesian word ‘Kopi’ (coffee) and ‘Luwak’ (a local name for the Asian palm civet). In some regions, locals call the animal ‘Musang,’ making the coffee also known as Kopi Musang. Essentially, it’s coffee made from beans that have been eaten, partially digested, and then excreted by this small, tree-dwelling mammal.

The process begins when civets—nocturnal, cat-like animals—select and consume ripe coffee cherries. They digest the fruit’s fleshy part but can’t break down the hard coffee beans inside. Those beans pass through the civet’s gastrointestinal tract, where gastric acids and enzymes alter their protein structure, before being excreted intact.

The Original Discovery and Historical Context

Kopi Luwak’s origin dates back to the early 18th century during Dutch colonial rule in Indonesia. The Dutch established large coffee plantations in Sumatra and Java but prohibited local workers from harvesting or consuming the coffee cherries. The locals noticed that civets were eating the ripest, sweetest coffee fruits and later excreting the beans undamaged. Curious, they collected, cleaned, and brewed those beans—and discovered a surprisingly smooth, less bitter cup.

Coffee expert Chris Rubin once described it as having ‘rich and intense aroma, with an incredibly thick, syrupy body and a chocolatey finish that lingers on the tongue.’ However, such praise is rare in modern specialty circles.

How Kopi Luwak Is Really Made (Step by Step)

Traditionally, the process involves:

• Natural Selection: Wild civets choose only the ripest, sweetest coffee cherries to eat.
• Digestive Fermentation: In the civet’s stomach, proteins in the coffee beans are partially broken down, reducing bitterness and altering flavor compounds.
• Excretion: The beans are expelled in the civet’s feces, still intact.
• Cleaning: The beans are carefully collected, washed, and separated from the manure.
• Drying & Roasting: The beans are dried (either naturally or mechanically) and then roasted like regular coffee beans.

This natural fermentation is said to create a smoother, fuller-bodied cup with lower acidity—but the reality today rarely matches this ideal.

The Dark Side: Factory Farming and Counterfeits

Originally a rare, wild product, Kopi Luwak became commercially viable only when farmers began capturing and force-feeding civets in captivity. Today, most ‘Kopi Luwak’ is not made from beans selected by wild civets, but from beans fed to civets kept in filthy, cramped cages. These animals often suffer severe stress, leading to self-harm and death.

Worse, around 85% of coffee sold as Kopi Luwak is fake. Many producers slap the label on ordinary beans to inflate prices. Even ‘authentic’ commercial Kopi Luwak is typically industrially produced, with no natural selection or ethical sourcing involved. The civets are usually given unsorted, low-quality beans, removing the key element of natural quality control.

What Does Kopi Luwak Actually Taste Like?

Opinions vary wildly. Some early tasters praised its syrupy body and reduced bitterness. Coffee consultant Chris Rubin highlighted its thick, chocolatey mouthfeel. But the Specialty Coffee Association of America (SCAA) has been far more critical, stating that industry consensus is the coffee simply doesn’t taste very good. SCAA notes that Kopi Luwak scores significantly lower than other specialty coffees and that its flavor is often muted and bland.

Washington Post food writer Tim Carman famously called it ‘like Folgers, but worse—like bathing in the water of a petrified dinosaur turd.’ Tasters report flat, lifeless flavors with no brightness or complexity. While some drinkers may perceive mild sweetness or richness, these qualities are often attributed to the story rather than the cup.

Why Civets Were Originally Involved

Wild civets instinctively seek out the ripest, sweetest coffee cherries. This natural selection meant the beans they consumed were already of higher quality. During digestion, the civet’s stomach acids and enzymes break down proteins that contribute to coffee’s bitterness. The result is a bean that, once roasted, produces a cup with lower perceived acidity and a smoother mouthfeel.

However, this effect is not unique to civets. The real distinction originally came from the civet’s choosiness and the unique fermentation process—but those elements are missing in almost all commercial production today.

Is Kopi Luwak Still Produced Ethically?

Virtually none of the Kopi Luwak sold globally today is ethically sourced. The vast majority comes from caged civets, often abused and force-fed. Even when civets are involved, the beans are typically not selectively eaten by the animals, and the processing lacks the natural quality filter that once made it unique. Experts agree: if you’re drinking store-bought Kopi Luwak, chances are it’s both inhumane and overhyped.

Frequently Asked Questions

What is Kopi Luwak coffee?

Kopi Luwak is coffee made from 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 changes their chemical structure and is said to reduce bitterness. The beans are then collected, cleaned, and roasted.

Why is Kopi Luwak so famous?

Kopi Luwak gained fame because of its unusual production method—beans processed through an animal’s digestive tract—and early reports of a smooth, rich, low-acid cup. Its rarity and strange backstory also contributed to its notoriety and high price.

Is Kopi Luwak safe to drink?

Yes, Kopi Luwak is safe to drink once the beans have been properly cleaned and roasted. The digestive process removes the cherry fruit, and thorough washing removes any biological contaminants. However, ethical concerns about how the beans are sourced are widespread.

Does Kopi Luwak really taste better?

Most specialty coffee experts agree that Kopi Luwak does not taste better than high-quality conventionally processed coffee. Some historical tasters noted a smooth, chocolatey profile, but modern reviews often describe it as flat, lifeless, or overly bland.

How is Kopi Luwak made today?

Today, most Kopi Luwak is mass-produced using caged civets that are force-fed unsorted coffee beans. The beans are collected from their feces, cleaned, and roasted. Very little of the original natural selection or ethical wild collection remains in commercial production.

Where does Kopi Luwak come from?

Kopi Luwak originates in Indonesia, particularly on the islands of Sumatra and Java. The term ‘Luwak’ refers to the Asian palm civet in local languages. Some regions also call it Kopi Musang. The same process has been imitated in other countries, but Indonesia remains the origin of traditional Kopi Luwak.
