Ever wondered just how long that open bottle of wine will keep for? It turns out that the answer depends on entirely on the type and quality of wine left in the bottle. Generally higher quality wines last longer. On average though, both white and red wines last roughly three after opening. Beyond that, the shelf life depends most heavily on how quickly the wines absorb oxygen once exposed to it, with the general rule of thumb being that the more oxygen absorbed, the quicker the wine is likely to spoil.
Key Takeaways:
- Really high-grade, single-vineyard wines with a high fill level will last for at least a week in the fridge, in my own experience. Even with slight loss of aroma, it will still be palatable.
- The more robust the red wine, the more tannin it has to protect itself against oxygen. So, the denser the red wine, the better it will present itself.
- Sparkling wines enjoy protection via their own carbon dioxide, but open bottles need proper, purpose-made stoppers that firmly clamp the bottle shut.
