Store wine away from heat and direct light, with a sound closure and as little temperature fluctuation as practical. For an opened bottle, reseal and refrigerate the remainder. Keeping wine for months and serving it with dinner are different jobs, so one “ideal temperature” cannot answer every storage question.
First decide how long you are keeping it
A bottle for this weekend does not need the same arrangements as wine intended for years of ageing. For short-term storage, choose a stable, shaded position away from a cooker, radiator or sunny window. Avoid leaving bottles in a hot car while finishing other errands.
For longer storage, suitable temperature control becomes more valuable. WSET gives 10–15°C as a long-term storage range and emphasises steady conditions and protection from light. That is different from the temperature you might choose to serve a fuller red.
Should bottles lie on their sides?
For wine closed with a natural cork and kept for an extended period, horizontal storage is a conventional way to maintain contact between wine and cork. Screw-capped bottles do not require that contact. Follow specific producer guidance where supplied, especially for unusual closures or formats.
Do not transfer this advice automatically to spirits: tequila storage generally favours an upright bottle. The contents and closure both matter.
Is an ordinary fridge a wine cellar?
A household fridge is useful for chilling before service and preserving an opened bottle. It is not the same as a controlled environment selected for ageing wine over a long period. A dedicated wine fridge can offer more suitable control, but it is not an essential purchase for someone buying bottles to use soon.
Before spending money, work out what you actually keep and for how long. An expensive storage solution cannot make a wine suitable for ageing if the wine was made for early drinking.
What to do with an opened bottle
- Keep the remaining wine out of prolonged warmth.
- Close it promptly with a sound stopper or cap.
- Refrigerate it, including red wine.
- For sparkling wine, use a pressure-rated sparkling stopper.
- Bring a red or fuller white gradually towards its preferred serving temperature when needed.
WSET’s guide to preserving opened wine discusses limiting air exposure and using cold storage. A smaller clean, food-safe bottle can reduce headspace for still wine, but transferring is only worthwhile if you can do it cleanly and close it properly.
How many days will it last?
The answer varies with wine style, closure, temperature, headspace and prior handling. Avoid treating one number as a guarantee for all wines. Our guides to opened red wine, white wine in the fridge and Prosecco after opening separate the practical cases.
Freshness can decline before a wine looks unusual. Conversely, an unfamiliar deposit is not something to diagnose from an age estimate alone. If the bottle’s identity, seal or cleanliness is uncertain, do not taste it as a safety test.
Keep storage notes simple
Write the opening date on a removable label. For a collection, record the bottle, vintage, purchase source and where it is stored. That is enough to prevent forgotten bottles and helps you distinguish storage questions from serving-temperature questions.
If a bottle develops sediment, decanting may help separate it at service. It does not reverse heat damage or make unsuitable long-term storage harmless.
