What Is Kopi Luwak Coffee and How to Brew It

You’ve heard the stories—coffee made from beans that have passed through a civet’s digestive system. But what is it really like to drink? If you’ve ever wondered whether kopi luwak lives up to the legend, or how to actually brew it without making a mistake, this is your straightforward guide.

The short answer: Kopi Luwak is best brewed at 80°C. Testing shows that higher temperatures bring out unpleasant odors, while lower temps make it weak. That 80°C sweet spot balances flavor and aroma best.

Kopi Luwak is one of the most talked-about—and controversial—types of coffee in the world. It originates from coffee beans that have been eaten and excreted by the Asian palm civet, a small mammal native to Southeast Asia. The civet’s digestive process is said to partially ferment the beans, altering their flavor profile. This particular batch, brought back from Indonesia by a colleague, weighed just 100 grams and was reportedly made from Robusta beans, which the civets favored.

What Makes Kopi Luwak Different?

Kopi Luwak stands out not because of the species of coffee bean, but due to the unique fermentation process inside the civet’s gut. The beans are ingested, fermented during digestion, and then expelled. Producers then collect, clean, and roast the beans. This process is said to reduce acidity and create a smoother cup—but results vary. In this case, the beans were Robusta variety, which typically have a stronger, more bitter profile than Arabica, yet the civet processing reportedly mellowed it.

How to Brew Kopi Luwak Properly

Brewing kopi Luwak requires precision. Through trial and error, the recommended water temperature is 80°C. Here’s what happened when testers varied the temperature:

• Too hot (above 80°C): Produced a strong, off-putting fishy or barnyard odor.
• Too cool (below 80°C): Resulted in a weak, under-extracted cup with little flavor.
• 80°C: Delivered the most balanced cup, with the unique kopi luwak character coming through clearly.

The coffee was brewed using a Swissgold dripper in the office setting, chosen for its ease of use. The grind size and brew method weren’t specified in detail, but standard pour-over parameters were likely applied given the equipment.

What Does Kopi Luwak Taste Like?

Expect a cup that is not particularly acidic or bitter. The overall flavor is unusual—some tasters noted a distinct, somewhat animal-like aroma, but also found the taste intriguing. This particular batch lacked sharp sourness or bitterness, and instead delivered a unique scent and flavor profile that many found worth trying at least once. The body was smooth, and the aftertaste lingered without harsh edges.

Frequently Asked Questions

What exactly is kopi luwak coffee?

Kopi luwak is coffee made from beans that have been eaten and excreted by the Asian palm civet. The beans ferment slightly in the civet’s digestive tract before being collected, cleaned, and roasted. This process is said to change the flavor, often reducing acidity.

Why is 80°C the best brewing temperature for kopi luwak?

Brewing kopi luwak at 80°C avoids the off-putting odors that come from over-extraction at higher temperatures, and also prevents under-extraction and weakness that occurs at lower temperatures. This temperature provides the most balanced extraction for this unique coffee.

Does kopi luwak have to be made from Robusta beans?

No, kopi luwak can be made from either Arabica or Robusta beans. In this case, the beans were from Robusta variety, which the civets preferred. However, the process itself is not limited to one coffee species.

What does kopi luwak taste like compared to regular coffee?

Is it safe to brew kopi luwak at higher temperatures?

Brewing kopi luwak at temperatures higher than 80°C can bring out strong, unpleasant odors, often described as fishy or barnyard-like. It’s safer and more flavorful to stick to around 80°C for optimal taste.

Can I brew kopi luwak using a standard pour-over method?
