How to Store Red Wine in Australia: A Simple Guide [2026]

The simplest answer is to keep unopened red wine somewhere cool, dark and steady. For most homes, a temperature around 15–20°C is a sensible target. Avoid direct sunlight, hot kitchens and places that heat up during the day.

If you will drink the wine within a few months, a cool internal cupboard may be enough. If you want to keep valuable bottles for several years, a wine fridge or professional storage is the safer choice.

What Is the Best Temperature for Storing Red Wine?

Aim for a stable temperature of about 15–20°C.

The Australian Wine Research Institute (AWRI) says long periods above 25°C can affect wine quality. It also reports that temperatures above 40°C may cause visible and flavour changes within days.

There is no honest countdown that says a bottle is safe for exactly three days at one temperature and ruined on the fourth. The result depends on how hot it became, how long the heat lasted, the wine, the closure and its age.

My practical rule is simple: the longer I want to keep a bottle, the more careful I am about temperature.

Can Red Wine Be Stored at Room Temperature in Australia?

Yes, but “room temperature” means different things in different homes.

A dark cupboard that remains below 25°C is very different from a kitchen that reaches 30°C in summer. Before choosing a storage place, put a small thermometer there for a week. Check the highest temperature, not just the reading at night.

Good places may include:

- an internal cupboard away from windows

- a cool spare room

- a cupboard under the stairs

- a temperature-controlled wine fridge

Avoid:

- garages and sheds

- the top of a refrigerator

- cupboards beside an oven

- sunny rooms and window shelves

- car boots, even for a short stop on a hot day

Will One Hot Australian Summer Ruin My Wine?

Not every warm day ruins a bottle. The greater risk is high heat that continues for a long time, or repeated heating and cooling.

AWRI research shows that higher storage temperatures speed up the reactions that change wine. Fresh fruit aromas can fade, and the wine may develop older, flatter or cooked flavours sooner than intended. Large daily temperature swings should also be avoided because the wine expands and contracts. This may contribute to leakage or movement around the closure.

If a heatwave is coming:

1. Move the bottles to the coolest dark room in the house.

2. Keep them away from outside walls and appliances.

3. Use a regular refrigerator temporarily if the alternative is severe heat.

4. Do not leave wine in a parked car.

Do I Need a Wine Fridge?

You probably do not need one for a few everyday bottles that will be opened soon. A wine fridge becomes more useful when the wine is expensive, the house is hot, or the bottles will be kept for years.

Your situation	Practical choice
Drinking within a few weeks or months	Cool, dark internal cupboard
Keeping bottles through a hot summer	Wine fridge or the coolest stable room
Saving good wine for several years	Wine fridge is the safer option
Ageing valuable wine for 10 years or more	Quality wine fridge or professional storage

For storage, a single-temperature fridge is usually enough. Separate temperature zones are more useful when you want different wines ready to serve.

Buy for the bottles you really use. Wide Shiraz, Burgundy and sparkling bottles can reduce the stated capacity of a fridge.

Can I Use a Normal Kitchen Fridge?

Yes, for short-term protection or after opening. It is not the best long-term home for an unopened collection.

A kitchen fridge is colder than a wine cellar and is opened often. It may also be dry, which matters more for bottles sealed with natural cork. However, during extreme summer heat, it is safer to keep a bottle cool in the fridge than to leave it in a room at 30–40°C.

Let a refrigerated red warm gradually before serving. Storage temperature and serving temperature are not the same thing.

Should Red Wine Be Stored Upright or on Its Side?

For a bottle with a natural cork, storing it on its side remains a sensible choice for long-term cellaring because it keeps the cork in contact with the wine.

For a screw cap, upright or horizontal storage is fine. The cap does not need wine contact to remain sealed. Store it in whichever position is secure and makes the best use of your space.

AWRI also reports that a five-year study of two white wines found little difference between upright and horizontal storage. Temperature and light are usually more important than worrying about the exact angle of a bottle.

Do All Red Wines Improve With Age?

No. Correct storage protects a wine, but it does not guarantee that the wine will improve.

Many approachable reds are made to be enjoyed while their fruit is fresh. For example, Maison Blue South Australian Shiraz is ready to enjoy and does not need years in a cellar.

More structured wines may develop over time, but the ideal drinking window depends on the vintage and how the wine was made. Our Australian Shiraz guide explains the difference between easy-drinking and age-worthy styles.

How Can I Tell if Wine Has Been Damaged by Heat?

Possible warning signs include:

- wine leaking around the closure

- a cork that has moved upwards

- unusual loss of wine from the bottle

- faded fresh-fruit aromas

- cooked, stewed or oxidised flavours

These signs are not a perfect test. AWRI notes that heat damage can be difficult to prove without comparing the bottle with the same wine stored under known conditions.

An older red may also contain harmless sediment. Stand it upright before opening, then use our simple guide to decanting wine if you want to separate the clear wine from the deposit.

Red Wine Storage FAQs

Is 25°C too warm for red wine?

It is warmer than recommended. A brief rise does not automatically ruin the wine, but long periods above 25°C can affect quality and shorten its useful life.

Can I keep red wine in the kitchen?

Only if the location stays cool and dark. Avoid cupboards near the oven, dishwasher or refrigerator because these areas often become warm.

Does screw-cap wine need to lie down?

No. Screw-cap wine can be stored upright or on its side.

How should I store an opened bottle of red wine?

Close it, keep it upright and place it in the refrigerator. The Wine & Spirit Education Trust says a resealed red or white can remain relatively fresh for up to five days, although the exact time depends on the wine. Let the red warm slightly before drinking it again.

What matters most when storing red wine?

Keep it away from prolonged heat, strong light and large temperature swings. If you plan to keep it for years, use temperature-controlled storage.
