How long can an opened bottle of wine last?

Whether it's for a special dinner or a celebration, you might not finish a bottle of wine and wonder how long you can keep it after opening.

An opened bottle of wine starts to oxidize, but the duration depends on factors like light, temperature, sugar content, and alcohol level. Here’s a quick guide based on wine types:

• White Wine: Typically lasts up to 3 days if stored in the refrigerator with a cork to minimize oxidation and bacterial growth.

• Red Wine: Can be kept for 3 to 5 days in a cool, dark place (around 15°C) with a cork. If it smells like vinegar, it’s no longer good.

• Sweet White Wine: Due to higher sugar content, it can last up to a month.

• Champagne and Sparkling Wines: Generally last only 1 day after opening, as they quickly lose their bubbles and taste.

• Fortified Wines: These can last longer due to their higher alcohol content, but investing in a cork and vacuum pump can help extend their life.

For professionals in the restaurant industry, using advanced preservation techniques like vacuum or nitrogen systems can significantly improve wine longevity.

In summary: An opened bottle’s lifespan varies by type, but proper storage and tools can help maintain its quality.
