Umami is the fifth. It's the kind of taste you get from mushrooms, or olives, that doesn't quite fit the other four.
It's rather interesting. The term umami was coined in 1908 by a Japanese chemist. He suspected, but could not immediately prove, that it was a distinct type of taste sensation. Over time, evidence accumulated, but some scientists continued to fight a rearguard action against its recognition until 2009.
I can't think of any other discovery in modern times that had to fight 101 years for acceptance. I hate to be a cynic, but I have a sneaking suspicion that racism in general, and anti-Japanese sentiment specifically, was at least partially responsible for the long delay. I somehow suspect that if it had been discovered by an Italian or an American or even a Lithuanian, umami would have been in the general textbooks by 1925.
