Expiration & Storage Tips
When does sauvignon blanc white wine expire?
An unopened bottle of Sauvignon Blanc can last for 1-2 years if stored properly. This long-term storage might slightly degrade the quality but won't make the wine unsafe to consume. If you're keeping the wine for this length of time, try to store it in a cool, dark place with a consistent temperature. Once opened, a bottle of Sauvignon Blanc should be consumed within 1-3 days. If you store it in your fridge after opening, you can maintain its quality for about 5-7 days. Frozen wine defrosts relatively quickly in the refrigerator within a few hours, but be aware that freezing and defrosting wine can negatively affect its flavor and consistency.
How do you tell if sauvignon blanc white wine is bad?
The easiest way to tell if a Sauvignon Blanc has gone bad is by its smell. If the wine has an unusual odor, similar to vinegar, burnt rubber, or damp cardboard, it might be spoiled. You may also notice a sharp, sour taste, or the color may change to a darker shade. Apart from that, if the wine has not been stored properly, it may have a flat taste and might lack aroma.
Tips for storing sauvignon blanc white wine to extend shelf life
• Store unopened Sauvignon Blanc in a cool, dark place with a consistent temperature ideally between 45-65°F (7-18°C).
• The wine should be stored horizontally to keep the cork wet, which prevents it from drying out and letting in air.
• Once opened, reseal the bottle with a wine stopper and refrigerate immediately. Use within 5-7 days for the best flavor.
• Avoid storing near strong-smelling foods or substances as wine can absorb flavors.
• To preserve an open bottle longer, consider using a vacuum pump to remove air, slowing down the oxidation process.
• Freezing is not recommended for long-term storage due to potential flavor degradation.
