咖啡的十个小知识 ：咖啡因可能有助于提升女性性欲  

　　8. Caffeine Is Not The Bitter Culprit

　　咖啡因不是苦味源

　　Caffeine is not the main bitter compound in coffee. Rather, the pungent perpetrators are antioxidants.

　　导致咖啡口感苦的主要因素不是咖啡因，而是抗氧化剂。

　　9. Great Coffee Depends on Roasting and Brewing

　　浓郁的咖啡取决于烘焙和冲泡的技术。

　　When it comes to great flavor, coffee chemistry boils down to roasting and brewing. During roasting, oil locked inside the beans begins to emerge at around 400 degrees. The more oil, the stronger the flavor. Caffeine content goes up as the water spends more time in contact with the grounds, so regular coffee often has more of it than espresso or cappuccino. Darker roasts also yield more caffeine.

　　咖啡化学将咖啡的浓郁风味归功于烘焙和冲泡。当烘焙的温度高至400度时，咖啡豆内的油脂会流出来。油脂越多，口味越浓郁。咖啡因的含量则与用水量相关。普通咖啡通常比浓缩咖啡或者卡布奇诺所含的咖啡因更高。烘焙的颜色越深也会含有更高的咖啡因。

　　10. Coffee Was Discovered by Goats

　　咖啡是山羊发现的。

　　A millennium ago on a mountainside in Africa, a herd of goats kept a shepherd up at night after feasting on red coffee berries. The shepherd took his animals' discovery to some monks, and very long prayer sessions ensued. It's a good story, anyway.

　　一千年以前在非洲的一个半山腰上，一群山羊吃下了一种红色的咖啡果子后，在夜里兴奋异常以至于牧羊人不能入睡。牧羊人将这种果子送给传教士，并被一个相当长的人群进行传颂。这实际上只是一个美好的传说。
