What is the shelf life of opened port and sherry?

Port and sherry, like other fortified wines, have a longer shelf life than most unfortified wines due to their higher alcohol content and oxidation-resistant properties. However, even opened bottles of port and sherry will eventually degrade over time.

Unopened Bottles:

- Port: Unopened bottles of port can last several decades, even up to a century, when properly stored in a cool, dark place. Vintage ports, in particular, can develop and improve over time.

- Sherry: Unopened bottles of sherry can also last for several decades. However, finos and manzanillas, which are lighter and drier styles of sherry, tend to have a shorter shelf life compared to darker, sweeter styles like olorosos.

Opened Bottles:

- Port: Once opened, a bottle of port should be consumed within 1-2 months to enjoy it at its best. Longer exposure to air and oxygen will start to degrade the wine's flavors and aromas.

- Sherry: Opened bottles of sherry can last longer than port, usually around 3-6 months. As with port, it's best to consume it within this timeframe for optimal flavor and quality.

Storage Conditions:

- Both port and sherry should be stored in a cool, dark place, away from heat, sunlight, and excessive humidity. Ideal storage temperatures are between 55°F (13°C) and 65°F (18°C).

- Keep bottles sealed tightly to minimize oxygen exposure and prevent the wine from oxidizing and losing its freshness.

- Storing opened bottles of port and sherry in a refrigerator can help slow down the degradation process but remember to bring the wine back to room temperature before serving to allow its full flavors and aromas to develop.

It's important to note that the shelf life of opened port and sherry can vary depending on storage conditions and individual preferences. Always check the wine's appearance, aroma, and taste before consuming it if you have any concerns about its quality.
