The chemical compound 2-furanmethanethiol (2FM), with a strong roast coffee aroma, has been identified in sweet white wines made from the Petit manseng grape variety, and in certain red Bordeaux wines (made from the Merlot, Cabernet franc, and Cabernet sauvignon grape varieties). This was done by extracting specific volatile thiols using p-hydroxymercuribenzoate. The 2FM has also been found in toasted oak used in barrel-making. All the Petit manseng sweet white wines and some of the red Bordeaux wines analyzed contained between a few ng/L and several dozen ng/L of 2FM. Taking into account its very low perception threshold (0.4 ng/L in a model hydro alcoholic environment), 2FM could therefore contribute to the roast coffee aroma of certain wines.
化合物2-呋喃甲硫醇（2FM）具有浓郁的烘焙咖啡香气，已在由小芒森葡萄品种酿造的甜白葡萄酒以及某些波尔多红葡萄酒（由梅洛、品丽珠和赤霞珠葡萄品种酿造）中被鉴定出来。这是通过使用对羟基汞苯甲酸提取特定挥发性硫醇来完成的。2FM也在用于制作酒桶的烤橡木中被发现。所有分析的小芒森甜白葡萄酒和一些波尔多红葡萄酒中2FM的含量在几纳克/升至几十纳克/升之间。考虑到其极低的感知阈值（在模拟水醇环境中为0.4纳克/升），因此2FM可能会对某些葡萄酒的烘焙咖啡香气有所贡献。
