According to a study published in the journal Chemical Senses, oleogustus (Latin for "a taste for fat") qualifies as a sixth basic taste, as people could distinguish it from sweet, sour, bitter, salty, and umami. Unfortunately, oleogustus doesn't taste that great. Scientists speculate that it could function as a warning mechanism, similar to bitterness. This sets it apart from the traditional mouthfeel we tend to associate with fatty foods, which is pleasant.
