The Key to Civet Coffee Is in the Chemistry
Researchers found civet coffee beans have higher fat and flavor-enhancing compounds, explaining why this rare brew sells for over $1,000 per kilogram, supporting ethical production efforts.
On October 23, researchers from Central University of Kerala, India found that fermentation in Asian palm civet digestive tracts alters kopi luwak beans, increasing fats and aromatic compounds, Scientific Reports said.
Asian palm civets consume ripe cherries and excrete undigested beans collected from nearly 70 civet scats at five Robusta coffee estates in Kodagu, India for analysis.
The analyses found civet-processed beans had higher total fat and elevated fatty acid methyl esters, caprylic acid methyl ester and capric acid methyl ester, with lower protein, caffeine and acidity levels.
High prices have led to civet coffee farms keeping animals caged or force-fed, as beans sell for more than US$1,300 per kilogram and cups cost up to $75.
Because this study analysed unroasted Robusta beans while most civet coffee uses Arabica beans, researchers recommend authenticity testing and developing artificial fermentation methods.
