Example
There are many attributes of olive oil that indicate poor quality like being rancid, fusty, musty or winey; but having a bitter sensation on the tongue or a back of the throat sting, is not one of them. In fact, it is one of the best indications of an extra virgin olive oil"s antioxidant and anti-inflammatory value.
Additional information
bitterness is perceived more intensively at the tongue end.
