Is Indonesian Civet Coffee Good? How to Distinguish Authentic Lakun Kopi Luwak from Fakes

FrontStreet Coffee's Indonesian Luwak Coffee Introduction

On the Indonesian island of Sumatra, there lives a tree-dwelling wild animal called the "luwak" (civet cat). Local farmers typically consider finding "luwak" droppings a gift from heaven, because not every "luwak" dropping can be found by luck.

Once a few such "coffee beans" are found, locals bend down to pick them up, collect them carefully, and then, through several processes such as selection, drying, deodorization, processing, and roasting, create a rare, unique, and expensive coffee.

Civet coffee (Kopi Luwak) is made when luwaks select mature, sweet, plump, and juicy coffee cherries from coffee trees as food. After the cherries pass through their digestive system, only the fruit pulp is digested, while the extremely hard original coffee beans are excreted unchanged. People then extract the beans from the droppings for processing.

Because of this special production process, many people may find civet coffee hard to accept. The reality, however, is quite the opposite.

It is precisely because luwaks eat mature coffee cherries and excrete the beans through their digestive system that the beans undergo gastric fermentation, producing a coffee with a distinctive flavor.

This digestive process brings about unparalleled changes in the beans, resulting in a unique flavor with moderate body and acidity, a gentle aroma, and earthy notes. The taste is particularly fragrant and mellow, with a rich, rounded sweetness that other coffee beans cannot match.

This is because the luwak's digestive system breaks down the proteins in the coffee beans, significantly reducing the bitterness caused by those proteins while enhancing the rounded mouthfeel.

Civet coffee's special flavor comes from two sources: (1) the unique body odor of the luwak itself, and (2) the digestive process, which consumes a large amount of sugar. The body odor is quite distinctive and unavoidable. As for the effect of sugar consumption on taste, less sugar means less bitterness formed during caramelization in the roasting process. Being both specially fragrant and not bitter, many people find it delicious; being delicious yet scarce makes it expensive. This is also why many people use masked palm civets as substitutes for luwaks to produce what is claimed to be civet coffee — the two have similar body shapes, making it easy to pass off a fake.

In short: luwaks feed on coffee cherries as their staple food during the bean maturation season. After complete digestion, the sugar content is consumed, and the beans in the droppings lose their stickiness. The coffee beans do not stick together; once excreted and dried, they quickly disperse into individual particles in a sparse distribution.

FrontStreet Coffee Recommendation

Luwak coffee is expensive and hard to verify, but Sumatra's real character comes through just as clearly in FrontStreet Coffee's Mandheling lots, which celebrate the island's wild, earthy profile without any of the authenticity worries. FrontStreet Coffee's PWN Golden Mandheling is the benchmark: a wet-hulled Sumatran coffee from the Gayo highlands near Lake Tawar, screened to the top G1 standard and hand-sorted three times, then roasted medium-deep so it sits low in acidity with a thick body and notes of sandalwood, herbs, spice, roasted hazelnut, caramel, and dark chocolate. For the most classic expression of the island, FrontStreet Coffee's Lintong Mandheling comes from the traditional Lake Toba region in North Sumatra, roasted medium-deep to bring out caramel, dark chocolate, and toasted bread with the herbal, earthy depth luwak fans chase. Either one is a far more reliable way to enjoy what makes Sumatran coffee so distinctive.
