Is white wine still good to drink after 10 years?

It's unlikely that white wine will be good to drink after 10 years. Here's why:

* Oxidation: White wines are generally more delicate than red wines and oxidize more quickly. This means they lose their freshness, flavor, and aroma over time.

* Storage: White wine is best stored in a cool, dark, and humid place to prevent spoilage. Even if stored correctly, 10 years is a long time for a white wine to maintain its quality.

* Variety: Some white wines, particularly those with high acidity and good tannins, might age well for a few years (like a good Chardonnay or Sauvignon Blanc). But most will start to decline after 5 years.

Signs of Spoilage:

* Off-putting aroma: You might detect a vinegar-like smell, or notes of cardboard or wet paper.

* Cloudy appearance: The wine might be cloudy or hazy, indicating oxidation.

* Flat taste: The wine might have lost its acidity and complexity, tasting dull or bland.

In general, it's best to enjoy white wines within a few years of production. If you have a bottle that's older than 10 years, it's probably best to err on the side of caution and not drink it.

Exception:

* Some dessert wines like Sauternes or Tokaji can age for decades and even improve with time. These wines are fortified with brandy, which helps them to age gracefully.

If you're unsure about an older bottle of white wine, it's always best to consult with a wine expert. They can help you determine if the wine is still drinkable.
