What Causes Heat Damage in Wine?

Heat damage can result from prolonged or excessive exposure to high temperatures. This might happen if you’ve left a bottle in a hot car or if your wine storage area has experienced a heatwave. It's crucial to note that heat damage can be irreversible, impacting the wine's taste, aroma, and overall quality.

Signs of Heat-Damaged Wine

It can be difficult to detect wine that’s been damaged by heat with certainty. However, here are some common symptoms you can look for:

• Expanded Cork: If the cork in your wine bottle appears as if it has expanded or bulging out of the bottle, this is a sign that the wine has been exposed to heat. The increased temperature causes the wine to expand, pushing the cork outwards.
• Wine Leakage: In some cases, the pressure from the expanded wine will even cause it to leak out of the bottle. Check for sticky residue or wine stains around the cork or bottle's neck.
• Off Aroma: Heat-damaged wine often has unappetizing and off-putting aromas. It might smell cooked, stewed, or even burnt. This is a clear indication that the wine has suffered heat damage.
• Taste: The taste of heat-damaged wine may be flat, dull, or lacking in complexity and flavor. It may also have a heavy, syrupy texture. These are all signs that the wine’s chemical structure has been altered by heat.

Preventing Heat Damage

Prevention is key when it comes to protecting your wine collection. Follow these tips to ensure that your bottles remain in tip-top condition:

1. Proper Storage: Store your wine in a cool, dark place with a consistent temperature between 55-60°F. Avoid storing wine near windows or in rooms that experience extreme temperature fluctuations throughout the day.
2. Transportation: When transporting your wine, try to minimize its exposure to heat. Don’t leave wine bottles in hot vehicles or direct sunlight for extended periods.
3. Insulation: If you want extra protection, consider investing in insulated wine storage or a wine fridge to help regulate temperature and humidity.

How To Tell If Wine Is Heat Damaged Example:

Imagine you purchased a lovely bottle of red wine for a special occasion. You bring it home from the store, and it accidentally gets left in the trunk of your car on a hot summer day. When you finally retrieve it, you notice that the cork is bulging slightly out of the bottle, and there's a sticky ring around the neck of the bottle.

You decide to open the bottle and pour a glass, hoping that everything is fine. However, you're immediately hit with an off aroma that smells burnt and cooked. When you taste the wine, you find it to be flat and lacking any complexity or excitement.

Unfortunately, your bottle of wine has been heat damaged, and there isn't a way to reverse the damage. You can learn from this experience by storing and transporting wine more carefully in the future.

So, there you have it! Now you know what heat damage in wine looks like, and you're equipped with the knowledge to prevent it from happening in the first place.
