You may or may not have already opened your favorite bottle of Sauvignon Blanc and might be wondering about the specifics of its lifespan. 

Has it been sitting here for too long? Can I enjoy it at that dinner party I’m hosting next week if I reseal it? So let’s explore the lifespan of a Sauvignon Blanc.

Generally, white wines such as Sauvignon Blanc are higher in acidity, meaning they tend to have a longer lifespan, up to 5 days. That is, however, depending on if the wine is sealed and stored correctly. 

If the wine is not yet opened, it’s good to be stored for 3 to 5 years.

Pouring wine into a glass from a bottle in hand - How Long Does Sauvignon Blanc Last After It's Opened?

How long does Sauvignon Blanc last once opened (screw top vs. cork)?

It’s said that screw tops are ideal for white wines like Sauvignon Blanc anyways, whereas corks are ideal for red wines. White wines that have been resealed with a cork and placed within a wine cooler or chilled area will last anywhere between 5 to 7 days. 

However, when resealed with a screw top and placed in a chilled environment, consuming the wine within about three days for the best experience is recommended.


What can I do to make Sauvignon Blanc last longer?

There are different methods to utilize when trying to salvage your already opened bottle of Sauvignon Blanc. Most of the methods provided below utilize products on the market that assist in preserving your opened wine. 

Let’s start with the method that requires no fancy tools but only common sense! The best way to preserve your wine is to simply reseal it after serving your guests and place it in a chilled area. 

Chilling your wine (or any of those personal frozen meals) will slow the aging process giving you more time to enjoy the wine before it completely goes bad.

Now to the fancy tools! These are a good investment for anyone who drinks wine regularly and has built up quite the collection of open, half-consumed wine bottles in their fridge. No judgment here! 

The two products we will be telling you about here are basically a vacuum seal and something called a wine preservation system. 

The vacuum seal is self-explanatory. When resealing the wine, this vacuum seal will do its best to remove as much oxygen from the bottle as possible before sealing the bottle with an airtight seal. 

No oxygen in the wine bottle equals a slower oxidizing process which ultimately preserves the wine longer. 

The most popular wine preservation system comes from the brand Coravin. The device pokes a hollow needle through the cork of the bottle to serve the wine. 

Then, when you’re ready to preserve it, simply remove the device. The cork’s material will expand and basically reseal the wine as the needle is removed from the cork.


What should I do immediately after opening Sauvignon Blanc to make it last longer?

The best method to use right after opening your wine and serving it is to immediately reseal it and place it in a chilled environment. White wines like Sauvignon Blanc are more susceptible to oxidizing, so complete this practice as soon as possible.

Final thoughts on the lifespan of Sauvignon Blanc

White wines like Sauvignon Blanc can last anywhere between 3-7 days after being resealed and placed into a chilled environment. After opening, the best way to preserve your wine is to record it immediately after serving and place it back into its chilled environment. 

However, there are devices on the market to assist those who don’t mind paying the price to preserve their wine more efficiently.
