Term (also corker, cork taste, cork tone, leather tone, cone) for a dreaded wine defect that affects the flavour of many millions of bottles of wine every year, making them undrinkable. In Austria, this is also colloquially described as "der Wein stoppelt" (stubble = cork). It is characterised by a musty, mouldy and chemical smell of wet, rotting wood or leather. The odour is sometimes also described as earthy, in which the alcohol type geosmin is involved. The flavour is unpleasantly bitter and astringent. However, the defect can often only be perceived by smell. A typical characteristic is a lack of fruitiness or a partially or completely masked varietal character of the wine.
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
