Can you drink red wine after it been open for one year?

It's generally not recommended to drink red wine that has been open for a year. Here's why:

* Oxidation: Once wine is exposed to air, it starts to oxidize, which changes its flavor and aroma. This process happens more quickly in red wines due to their higher tannin content.

* Spoilage: Over time, bacteria and yeast can grow in open wine, spoiling its taste and making it potentially unsafe to drink.

* Loss of Freshness: The flavors and aromas of red wine will deteriorate significantly after a year.

Exceptions:

* Fortified Wines: Fortified wines like Port and Sherry have higher alcohol content, which slows down oxidation and can last longer open.

* Specific Wine Styles: Some red wines, like those with high acidity and tannins, may hold up better after a longer period. However, this is still generally not recommended.

What to do with open red wine:

* Drink it within a few days: For the best flavor, drink red wine within 3-5 days of opening.

* Use a wine preserver: These devices remove oxygen from the bottle, slowing down oxidation.

* Store properly: Keep opened wine in a cool, dark place.

* Consider using it in cooking: If the wine has gone bad, you can still use it for cooking.

Bottom line: While it's possible to drink red wine that has been open for a year, it's unlikely to taste good. For the best quality, enjoy it within a few days of opening.
