As connoisseurs in the United States, Europe and East Asia have discovered civet coffee in recent years, growing demand is fueling a gold rush in the Philippines and Indonesia, the countries with the largest civet populations. Harvesters are scouring forest floors in the Philippines, where civet coffee has emerged as a new business. In Indonesia, where the coffee has a long history, enterprising individuals are capturing civets and setting up minifarms, often in their backyards.

Neither the Indonesian government nor the Association of Indonesia Coffee Exporters breaks down civet coffee’s tiny share of Indonesia’s overall coffee production. The Association of Indonesian Coffee Luwak Farmers, created in 2009 to handle the rising demand for civet coffee, or kopi luwak, as it is called in Indonesian, said most civet producers were small-time businessmen who exported directly overseas.

Given the money at stake, fake and low-grade civet coffee beans are also flooding the market.

“Because of its increasing popularity, there is more civet coffee than ever, but I don’t trust the quality,” said Rudy Widjaja, 68, whose 131-year-old family-owned coffee store in Jakarta, Warung Tinggi, is considered Indonesia’s oldest.

Competition is touching off fierce debates. What is real civet coffee, anyway? Does the civet’s choice of beans make the coffee? Or is it the beans’ journey through the animal’s digestive tract? Can the aroma, fragrance and taste of beans from the droppings of a caged civet ever be as tasty as those from its wild cousin?

Vie Reyes, whose Manila-based company, Bote Central, entered the civet coffee business five years ago, said she bought only from harvesters of the wild kind. Ms. Reyes exports to distributors overseas — Japan and South Korea are her biggest markets — and also directly sells 2.2-pound bags for $500, or about $227 a pound.
