Definition

Cork taint is a fault where a chemical called TCA, usually from the cork, makes a wine smell of wet cardboard, damp basement, or musty must. It is a closure problem, not a flaw in the wine itself.

Why it matters for WSET

Cork taint is the classic example of a faulty wine in the WSET tasting method’s condition check, and a frequent exam point.

Example

A smell of wet newspaper is a sign of cork taint.
