How Do They Get Caffeine Out of Coffee Beans?

It’s one of those ques­tions I’ve always won­dered about. And maybe you have too. Just how do they extract caf­feine from cof­fee beans? In the first episode of a new Men­tal Floss series, “Big Ques­tions,” a guy named Craig, rock­ing a tight t shirt, gives us some answers. If I’m guess­ing right, the video relies fair­ly heav­i­ly on this Sci­en­tif­ic Amer­i­can arti­cle from 1999. It helps demys­ti­fy the process a lit­tle more.
