Sourness

Sourness, also known as sour, is a basic taste sensation perceived through hydrogen ions from acidic compounds interacting with taste bud receptors, and it can also refer to an unpleasant or acidic quality in taste, disposition, or tone. It is a warning sign for potentially spoiled food, though it is balanced in some food products by sweetness, and it is associated with a low pH.
