科技日报记者 张梦然 在印度西南部郁郁葱葱的罗布斯塔咖啡园里，一种神秘的小动物正悄悄参与着世界上最昂贵咖啡的 诞生。它叫椰子猫，也叫麝香猫，外形像猫又像浣熊，昼伏夜出，偏爱成熟的咖啡果。它吃下鲜红的咖 啡果，果肉在体内被消化，而坚硬的咖啡豆则原样排出体外。这些从粪便中采收、清洗、烘焙后的咖啡 豆，就是大名鼎鼎的猫屎咖啡，每公斤售价常常超过一千美元，被称为咖啡中的奢侈品。 这听起来让人皱眉：从动物粪便里捡出来的咖啡，凭什么这么贵？它真的比普通咖啡更好喝，还是 仅仅因为猎奇和炒作？围绕它的伦理争议、卫生疑虑和实际价值，多年来从未停歇。备受争议的猫屎咖 啡究竟特别在哪？科学或许正开始给出答案。 现在，印度科学家团队在《科学报告》上发表了一项研究，为这个谜题带来了新的线索。他们在印 度的5个咖啡园中，收集了68份野生椰子猫的粪便样本，并从中取出咖啡豆；同时，他们也从同一片土 地上采集了手工采摘的成熟咖啡果作为对照。经过仔细清洗和化学分析，结果令人惊讶：那些"历劫归 来"的咖啡豆，脂肪含量明显更高，尤其是两种名为辛酸甲酯和癸酸甲酯的脂肪酸甲酯（FAMEs）—— 这些物质，正是决定咖啡风味的关键角色。 科学家推测，咖啡豆 ...

Core Viewpoint - Cat poop coffee, known for its high price and unique production method, is considered a luxury item, but its taste is now overshadowed by other coffee varieties like Geisha coffee, which offers better flavor at a lower price [1][3][4]. Price and Quality Discrepancy - The wholesale price of cat poop coffee ranges from $300 to $800 per pound, while branded versions can exceed $1,000, with some reaching $3,000 per pound [1]. - In contrast, Geisha coffee, despite its superior taste, is relatively affordable, costing about 3 RMB per gram, translating to approximately 50 RMB for a cup, significantly cheaper than cat poop coffee [3]. Production and Scarcity - The scarcity of cat poop coffee is due to the limited population and dietary habits of civets, which leads to lower production volumes [4]. - Geisha coffee, being a cultivated variety, can be produced on a larger scale, making it more accessible and affordable [4]. Quality Concerns - The decline in the quality of cat poop coffee is attributed to the shift from wild to farmed civets, which do not select the best coffee cherries, resulting in inferior beans [4][5]. - The original appeal of cat poop coffee stemmed from the natural selection process of wild civets, which is now compromised in commercial production [4][5].
