Luxury coffee enthusiasts around the world have long been intrigued by the unique and expensive ‘cat poo’ coffee, also known as civet coffee. This specialty brew, made from coffee beans that have been eaten and excreted by civet cats, can fetch prices that are over 100 times higher than regular coffee. The distinctive flavor of civet coffee has puzzled scientists for years, but a recent study sheds light on the secret behind its taste.
Researchers have discovered that the beans processed by civets contain high levels of two fatty acids commonly found in dairy products. These fatty acids, caprylic acid, and capric acid, are known for their flavor-enhancing properties and may contribute to the unique taste of civet coffee. The study, led by zoologist Palatty Allesh Sinu at the Central University of Kerala in India, aimed to not only unravel the mystery of civet coffee’s flavor but also promote animal welfare by finding alternative ways to produce this sought-after brew.
Civet coffee, known as Kopi Luwak in Indonesia where it originates, has gained popularity globally for its exotic origins and luxurious price tag. The beans used to make civet coffee are collected from the feces of Asian palm civets, which have eaten the ripe coffee cherries. These beans are then roasted to create a coffee with a distinct flavor profile that can cost up to $75 per cup.
Despite the high demand for civet coffee, concerns have been raised about the welfare of civets in farms where they are kept in cages to produce the beans. Organizations like The Civet Project have highlighted the ethical issues surrounding these practices and the potential risks of zoonotic diseases.
The recent study conducted by Sinu and his team analyzed unroasted coffee beans harvested from wild civet scat samples in India to understand the chemical changes that occur during digestion and fermentation in the civet’s gut. Using gas-chromatography-mass spectrometry, the researchers identified higher concentrations of caprylic acid and capric acid in the civet-processed beans, indicating a potential link to the unique flavor of civet coffee.
While fatty acids play a role in shaping the taste of civet coffee, there are still many other compounds and factors at play in determining its flavor profile. Further research is needed to explore the complex chemistry of coffee flavor and how different variables, such as coffee variety and roasting methods, influence the final product.
Overall, the study provides valuable insights into the science behind civet coffee and offers potential alternatives to traditional production methods that prioritize animal welfare. By understanding the chemical processes that contribute to the flavor of civet coffee, researchers hope to create a more sustainable and ethical way to enjoy this luxury brew.
