How to Identify Corked Wine

Identifying Cork Taint: A Somber Reality for Wine Enthusiasts

Explore the nuances of corked wine, a phenomenon affecting approximately five percent of cork-sealed bottles. Uncover the signs of cork taint and gain insights into the intricate world of wine flaws.

What Isn’t Corked Wine?

• Exclusions from the Definition:
  • Presence of cork particles or tartrate crystals in the wine does not signify cork taint.
  • Smelling the cork itself or utilizing alternative closures like screw caps and synthetic corks eliminates the possibility of encountering corked wine.

Understanding the Origins of Cork Taint

• Cork’s Natural Pores and Bacteria:
  • Cork, a natural product derived from trees, inherently carries bacteria in its pores.
  • Cork taint occurs through an enzymatic reaction between chlorophenol, a natural flaw in cork, and fungus, resulting in the creation of the compound TCA (2,4,6-trichloroanisole).

Detecting Corked Wine

• Aromatics Disrupted by TCA:
  • TCA, when in contact with wine, disrupts its aromatics, imparting an earthy, musty smell.
  • Identifying corked wine involves recognizing the absence of expected notes in the wine’s aroma, often likened to wet newspaper, musty basement, or wet dog.

Dealing with Corked Wine

• Return Policy and Consumer Rights:
  • Drinking corked wine is not harmful, as the only poisonous element in wine is alcohol.
  • Consumers have the right to return corked wine at restaurants, as they are spending money on a product that does not meet expectations.

Preventing Corked Wine Experience

• Opting for Screw Caps:
  • The introduction of screw caps aimed to address cork taint issues associated with natural corks.
  • Over 30 percent of global wines now utilize screw caps, offering a reliable alternative to traditional cork closures.

Embracing Learning Opportunities

• Transforming Setbacks into Learning:
  • Experiencing corked wine provides valuable insights into identifying and avoiding such instances.
  • Consumers are encouraged to view these experiences as opportunities for expanding their wine knowledge.
