How Kopi Luwak Coffee Is Made: Traditional Process & Yield

Ever wondered how kopi luwak—infamously known as ‘cat poop coffee’—is actually made? Despite its strange reputation, this coffee originates from a real, centuries-old process in Indonesia where civet cats consume coffee cherries and excrete the beans. The key lies in how those beans are recovered, cleaned, and processed into what many consider one of the world’s rarest specialty coffees.

The short answer? For every kilogram (2.2 lbs) of civet droppings, only around 150 grams (about 5.3 oz) of coffee beans can be salvaged. Then, during roasting, another 20% is lost. That leaves just over 120 grams of final roasted coffee per kilo of waste—an extremely limited yield that caps global supply at under 400 kilograms per year.

What Is Kopi Luwak and How Is It Different?

Kopi luwak, also called civet coffee, is unique not because of the animal involved but due to the way coffee cherries are processed inside the civet’s digestive tract. Unlike conventional washed or natural processing methods—where fruit is removed by hand or left to dry in the sun—kopi luwak beans are first eaten by civets, then fermented internally, and finally excreted. This natural fermentation inside the animal is said to create distinctive flavour characteristics not achievable through standard processing.

Step-by-Step: Traditional Kopi Luwak Processing

Once civet droppings are collected, Indonesian producers follow a careful multi-step method:

• Remove the silver skin: The outer, silvery-grey husk of the coffee bean is carefully taken off.
• Wash thoroughly: The beans are rinsed with water to remove any remaining waste material.
• Dry in the sun: The beans are spread out and left to dry naturally under sunlight.
• Roast the beans: Finally, the dried beans are roasted, just like regular coffee, to develop flavour.

Why Is Kopi Luwak So Rare?

The rarity of kopi luwak comes down to two main factors: extremely low yield and labour-intensive processing. From one kilogram of civet droppings, only about 150 grams of usable coffee beans are extracted. Then, during roasting, approximately 20% of those beans are lost. Combined, that means less than 120 grams of final roasted coffee results from each kilo of droppings. On a global scale, this limits annual production to no more than 400 kilograms—making it one of the scarcest coffees in the world.

Frequently Asked Questions

How many coffee beans are recovered from civet droppings?

From one kilogram (about 2.2 pounds) of civet droppings, approximately 150 grams (roughly 5.3 ounces) of coffee beans are extracted. That’s less than 15% of the original weight.

How much coffee is lost during roasting?

During the roasting process, around 20% of the recovered kopi luwak beans are lost. This further reduces the already small yield from the original droppings.

What makes kopi luwak processing different from regular coffee?

Unlike typical washed or natural processing, kopi luwak beans are first digested by civet cats. This internal fermentation alters the beans’ characteristics before they are collected, cleaned, dried, and roasted.

Why is kopi luwak so limited in supply?

The combination of very low bean recovery (150g per kg of droppings) and significant roasting loss (20%) caps the yield. Global production is estimated to be no more than 400 kilograms per year.

Where is kopi luwak traditionally produced?

Kopi luwak is traditionally made in Indonesia, where local producers collect civet droppings, clean the beans, and process them using methods developed over generations.
