How Long Does White Wine Last Once Opened Screw Top

So, you’ve just enjoyed a fantastic glass of white wine, but now you're left with an opened screw top bottle. You might wonder how long it will last and if it's still okay to enjoy when the next wine night rolls around. Fear not, fellow wine lovers! The Black Wine Club is here to answer your questions and provide some much-needed guidance on how long your opened white wine will last once it's exposed to some air.

Factors That Impact the Shelf-Life of an Opened Screw Top White Wine

1. Type of White Wine

Some white wines are more resilient and can last a bit longer once opened, while others are more delicate and spoil quickly. Typically, lighter white wines have a shorter lifespan than fuller-bodied or aged whites. Here's a rough guideline:

• Light, unaged white wines: 3-5 days (e.g., Pinot Grigio, Sauvignon Blanc)
• Full-bodied or moderately aged white wines: 5-7 days (e.g., Chardonnay, Viognier)
• Fortified or dessert wines: 1-3 weeks (e.g., Sherry, Madeira)

2. Storage Conditions

The way you store your opened white wine can significantly impact how long it lasts. Remember the following key factors in Wine Storage 101:

• Temperature: Keep your opened wine in a cool place, ideally between 45°F - 65°F (7°C - 18°C).
• Light: Store your wine in a dark place, as direct sunlight or bright lights can degrade the wine's quality.
• Air exposure: Limit the wine's exposure to air by sealing it tightly with its screw top or using a wine stopper.

3. Quality of the Wine

High-quality white wines tend to last longer than lower quality wines because they usually contain more natural preservatives that help fend off spoilage.

How to Improve the Shelf-Life of Your Opened White Wine

1. Re-Seal the Bottle

Immediately after pouring yourself a glass, be sure to re-seal the bottle tightly using its original screw top or a wine stopper. Minimizing air exposure is crucial in extending your wine's life.

2. Refrigerate the Wine

Refrigerating your opened white wine is essential in slowing down oxidation and bacterial growth. Remember to keep it upright and away from strong-smelling foods.

3. Choose a Wine Preserver

Consider using a wine preserver, also known as a wine vacuum pump, to extract the air from the bottle before re-sealing. This further minimizes oxygen exposure and can extend your wine's life by a few days. There are also wine preservation sprays, like Private Preserve, that create a protective layer of inert gas inside the bottle.

4. Be Cautious About the Half-Life of Your White Wine

Once you've reached the halfway point of your bottle, the remaining wine will age twice as fast due to the increased air exposure. Keep this in mind and consider transferring the wine to a smaller container if needed.

How Long Does White Wine Last Once Opened Screw Top Example:

Imagine you have a bottle of unaged Sauvignon Blanc with a screw top that you opened and enjoyed with dinner. You re-sealed the bottle tightly, stored it in your refrigerator, and used a wine vacuum pump to help preserve its freshness. Following these steps, you can expect the wine to last between 5-7 days before its quality starts to degrade. However, if you didn't take these precautions, the wine might only last 3-5 days before it becomes less enjoyable to drink.

Now that you have a clear understanding of how long your opened screw top white wine will last and some essential tips on preserving its shelf-life, you can enjoy a glass guilt-free without worrying about wasting a good bottle of a vino.
