One of the most common questions we get from our guests at Wine in the Cape is, “How long does an open bottle of wine last?” Whether you’re saving the last glass from your favourite Chardonnay or wondering if that forgotten red on the counter is still drinkable, understanding how long wine lasts after opening can help you enjoy every drop—without waste.
The short answer? It depends on the type of wine and how it’s stored.
Below, we break down the typical shelf life of open wine by style, with some practical tips to keep your bottles fresher, longer.
Sparkling Wine
1–3 days in the fridge with a sparkling wine stopper
Sparkling wines lose their fizz quickly, especially if left unsealed. Traditional method wines like Champagne and Cap Classique tend to hold their bubbles a little longer than tank method wines like Prosecco, thanks to their higher pressure at bottling. A sparkling wine stopper is essential if you want to preserve the magic.
Tip: Store upright and always keep cold to slow down the loss of carbonation.

Light White, Sweet White & Rosé Wines
5–7 days in the fridge with a cork
Fresh, fruit-forward wines like Sauvignon Blanc, Riesling, and Rosé usually hold up quite well for several days. You’ll notice a subtle change in aroma and flavour after the first day, as oxidation gently softens the wine.
Tip: Keep bottles sealed and refrigerated to preserve brightness.
Full-Bodied White Wines
3–5 days in the fridge with a cork
Richer whites like oaked Chardonnay or Viognier are more prone to oxidation. These wines have already had more oxygen exposure during ageing, so they tend to evolve faster once opened.
Tip: Use a vacuum stopper if you regularly open full-bodied whites.
Red Wines
3–5 days in a cool, dark place with a cork
Tannins and acidity are natural preservatives in red wine. Bold reds like Cabernet Sauvignon or Syrah may actually taste better a day or two after opening. Lighter reds like Pinot Noir are more delicate and fade sooner.
Tip: Store open red wines in a wine fridge or a cool cupboard. When in doubt, your regular fridge is better than room temperature.
Fortified Wines
Up to 28 days in a cool, dark place with a cork
Fortified wines like Port, Sherry, and Marsala have excellent staying power. High alcohol content and residual sugar slow down spoilage. However, light and heat will still dull the flavours over time.
Tip: Keep fortified wines sealed and out of sunlight. Sweeter styles tend to last longer.
Why Wine Goes Bad
Two main chemical reactions are at play when a wine turns:
- Acetic acid bacteria convert alcohol into acetic acid (vinegar) and acetaldehyde, giving off a sharp, sour smell.
- Oxidation causes wine to lose its fresh fruit character and develop nutty, bruised fruit flavours.
Keeping wine at a lower temperature slows both reactions. That’s why fridges and wine coolers are your best allies for wine longevity.
