AsianScientist (Jan. 18, 2026) – Civet espresso, higher often known as kopi luwak, is a premium and highly-priced coffees globally, identified for its distinctive aroma, style, and dietary worth.
The beans, which may promote for as a lot as USD 1,000 per kilogram, are harvested from the faecal matter of civets — often Asian palm civets (Paradoxurus hermaphroditus) — which eat ripe espresso berries and digest the pulp while the beans inside go by the digestive system.
Though this kind of espresso has been harvested and bought for over 100 years, there’s nonetheless debate round whether or not the bizarre harvesting technique adjustments the espresso’s chemical composition.
A brand new research revealed in Scientific Reviews may need solutions to this. Researchers from Kerala, India, have discovered that espresso beans harvested from the faeces of the Asian palm civet might have increased ranges of fat and different key flavour-enhancing compounds than historically harvested beans.
“Civets feed on ripened espresso berries, which bear digestion, absorption, and a pure fermentation course of throughout their passage by the intestine. Whereas the pulp will get digested, the beans are excreted by their faces,” the researchers acknowledged within the research.
The research investigated the bodily and chemical traits of civet-derived and manually collected Robusta espresso from conventionally managed and organically managed espresso estates throughout Kodagu, which ranks among the many highest coffee-producing districts in India.
The staff of researchers from the Central College of Kerala, India, collected 68 faecal matter samples from wild civets on 5 estates rising Robusta espresso in January. The researchers additionally collected ripe espresso berries from every property for comparability.
“In our research space, situated inside the biodiversity hotspot of the Western Ghats, civets are a part of the pure ecosystem and devour fruits wildly,” the researchers acknowledged. “The civets within the space belong to 3 totally different species. Nevertheless, primarily based on our observations and former analysis, the Asian Palm Civet, a nocturnal mammal, is discovered most ceaselessly.”
The staff, led by Professor Palatty Allesh Sinu from the Division of Zoology, discovered that the civet beans had a considerably increased whole fats content material than the manually harvested beans. The civet beans additionally had considerably increased ranges of two fatty acid methyl esters (FAMEs) — caprylic acid methyl ester, and capric acid methyl ester.
“The chemical variations within the civet espresso are a results of fermentation of the beans within the digestive system of the civets, and that the variations doubtless have an effect on the espresso’s closing flavour,” the researchers acknowledged.
The upper fats content material would have an effect on the espresso’s aroma and style profile, while the upper ranges within the two FAMEs might add a dairy-like flavour.
The staff analysed unroasted beans for the research, because the roasting course of would additional have an effect on the beans’ chemical composition. In addition they famous that they analysed Robusta beans, while most civet espresso is produced utilizing Arabica beans.
