How long will a corked bottle of white wine stay fresh in the fridge?

A corked bottle of white wine will typically stay fresh in the fridge for 3-5 days.

However, there are a few factors that can affect this:

* Type of wine: Some whites, like Sauvignon Blanc and Pinot Grigio, are more prone to oxidation and will last less time than others like Chardonnay or Riesling.

* Quality of cork: Natural corks can allow more oxygen in, reducing shelf life.

* Storage conditions: The fridge should be set at a consistent temperature (around 40-45°F) and the wine should be stored upright to keep the cork moist.

Tips for extending freshness:

* Vacuum seal: Use a wine preserver to remove air from the bottle.

* Transfer to smaller containers: Pour the remaining wine into a smaller bottle or jar, leaving less air exposure.

* Add inert gas: Inert gases like argon can be used to displace oxygen and preserve the wine.

Ultimately, the best way to ensure freshness is to taste the wine. If it smells or tastes off, it's time to discard it.
