A wine fault is a sensory-associated (organoleptic [1]) characteristic of a wine that is unpleasant, and may include elements of taste, smell, or appearance, elements that may arise from a "chemical or a microbial origin", where particular sensory experiences (e.g., an off-odor) might arise from more than one wine fault. [2] Wine faults may ...
Chemical structure of 2,4,6-trichloroanisole (TCA), the compound primarily responsible for cork taint. Cork taint is a broad term referring to an off-odor and off-flavor wine fault [1] arising from the presence of 2,4,6-trichloroanisole (TCA), a chemical compound that represents one of the strongest off-flavors, and one "generated naturally in foods/beverages", in particular wines, that ...

In particular the affliction has received attention in connection to incidents of whites produced in Burgundy.
