How to recognize a corky wine and what to do in this case

December 24, 2024

Opening a beautiful bottle and discovering it's corked is a disappointment for any wine lover. Understanding what a corked wine is, knowing how to recognize it and reacting correctly can save a tasting.

What is a corked wine?

A corked wine has its aromas and flavors altered by a chemical contaminant called TCA (trichloroanisole). TCA develops when cork comes into contact with certain chemicals or molds.

The main causes

  • Contaminated corks: The main source of TCA comes from defective corks.
  • Storage problems: Poor bottle storage favors the appearance of this defect.
  • Production environment: Contaminated drums or premises can also contribute to the development of TCA.

Impact on wine

TCA does not make wine harmful to health, but it does alter its organoleptic qualities.

How do you recognize a corky wine?

Identifying a corked wine requires a little practice and attention to detail.

1. The smell

The smell of cork is the most obvious sign. It's reminiscent of damp cardboard, mold or an old basement.

2. The taste

A corked wine has an unpleasant, flat, bitter taste. The wine's usual aromas are masked.

3. The color

Although less common, a corked wine can also show visual signs, such as a dull or abnormal hue.

Steps to confirm that a wine is corked

1. Aerate the wine after uncorking

After uncorking the wine, let it air for a few minutes. If the corky smell persists, there's a good chance the wine has been tampered with.

2. Do a cross-test

Compare your wine with an identical bottle. If one is normal and the other is corked, the problem is probably the cork.

3. Ask for advice

Have another person taste the wine to confirm your diagnosis.

Discovering a corked wine is never pleasant, but there are several options open to you.

1. Turn the bottle upside down

If you bought the wine recently, return it to the seller. Most wine merchants accept returns of corked bottles.

2. Use a filter

Special filters can reduce the effect of TCA, but do not completely eliminate the problem.

3. Recycling wine

Use a corked wine to cook sauces or marinades. Cooking often attenuates defects.

4. Prevent the problem in the future

Invest in good bottle storage and choose wines with synthetic or screw caps, which are less prone to TCA.

How to prevent corky wine?

While it's impossible to completely eliminate the risk of corked wine, there are some precautions you can take.

1. Store your cylinders correctly

Good bottle storage reduces the risk of spoilage. Maintain a stable temperature (12-14°C) and humidity around 70%.

2. Check plugs

Inspect the plugs at the time of purchase or unplugging. Traces of mold or discoloration may indicate a problem.

3. Buy from reliable sources

Specialist wine merchants and renowned estates often have rigorous quality controls to prevent faulty corks.

Uncorking wine: a crucial step

Uncorking wine may seem simple, but it influences the quality of the tasting experience.

1. Use a suitable corkscrew

Choose a corkscrew that extracts the cork without damaging it. Lever or worm models are ideal.

2. Inspect plug

After unclogging, examine the plug. A cork in good condition should be soft, with no abnormal odors or cracks.

3. Aerate the wine

Aeration after uncorking eliminates any unpleasant aromas caused by too young or poorly stored wine.

Alternatives to cork stoppers

1. Synthetic plugs

These closures, made from plastic materials, eliminate the risk of TCA.

2. Screw caps

Wines with screwcaps offer effective conservation and avoid corking altogether.

3. Recent innovations

Some producers are exploring alternatives such as glass stoppers, which combine aesthetic appeal with practicality.

The importance of bottle conservation

Good storage extends the life of your wines and reduces the risk of problems.

1. Temperature and humidity

Maintain a constant temperature and humidity level to avoid cork deterioration.

2. Bottle position

Keep your bottles lying down to keep the corks moist and prevent them from drying out.

3. Avoid vibrations

Vibration disrupts the aging of wine and can affect its long-term quality.

Conclusion

Knowing how to recognize a corked wine and react effectively is essential for any wine lover. With good bottle storage and special care when uncorking wine, you reduce the risk of encountering this problem. In case of doubt, don't hesitate to exchange the bottle or find creative solutions for using it differently.
