Kopi Luwak Cupping Notes: World’s Most Expensive Coffee

When people ask why kopi luwak—also known as civet coffee—is famous, the answer isn’t just about taste. It’s the curiosity factor: the idea that a cat-like animal digests coffee cherries and ‘produces’ beans that sell for record prices. But beyond the novelty, what does it actually taste like? I had the rare chance to try a locally roasted batch in Indonesia, thanks to a Korean expat with family ties to a Sumatran farm.

In short: this dark-roasted kopi luwak surprised me. Despite the deep roast level, it had almost no bitterness or acidity. The cup was smooth, balanced, and reminiscent of Pu'er tea—mellow, with a gentle finish and soft aroma that built in complexity after a few sips.

What Is Kopi Luwak and How Is It Made?

Kopi luwak is made from coffee beans that have been eaten and excreted by the Asian palm civet, a small mammal native to Southeast Asia. The civet selectively eats ripe coffee cherries, and during digestion, the beans undergo unique fermentation inside the animal’s gut. They are then collected from the droppings, cleaned, and roasted. This process is said to alter the beans’ structure and flavour profile.

The Roast Level and First Impressions

The kopi luwak I tasted was roasted to what Indonesians call ‘full city roast’—a relatively dark level that typically brings out heavier, more bitter notes in most beans. Yet this cup defied expectations. The roaster (the farm owner’s wife) used hand-brewed pour-over to prepare it. The result was unexpectedly soft: minimal bitterness, almost zero acidity, and a very mellow body. The overall effect was smooth and balanced, almost meditative. There was no sharpness, just a quiet depth.

Flavour Profile and Aftertaste

This particular cup had a rounded, earthy character that some might compare to aged pu'er tea. There was no bright fruit or acidity commonly found in light or medium roasts. Instead, it offered a subtle, comforting warmth. The finish had a slight sweetness—what the taster described as a gentle aftertaste that lingered pleasantly. The aroma was delicate but developed more nuance as the cup progressed. At first sip, it seemed light, but with each subsequent drink, the flavours accumulated into a cohesive, unique experience.

Why Is It So Famous—and Who Drinks It?

Kopi luwak gained global fame partly due to its shocking production method and its former title as the world’s most expensive coffee. Its muted flavour profile and lack of bitterness have made it especially popular in Japan and South Korea, where milder, smoother coffees are often preferred. While my sample may not have been freshly roasted, it still illustrated why this coffee continues to fascinate: it’s subtle, understated, and unlike any other brew.
