Can you store wine in summer without a wine cellar?

Summer is often a tricky time for storing wine. High temperatures, temperature variations and exposure to light can rapidly alter the quality of bottles, especially when stored without a wine cellar.

Although some bottles can temporarily withstand high temperatures, prolonged exposure to heat can accelerate aging and alter the wine's aromas. So it's important to know how to protect your bottles during the summer months.

Why is heat bad for wine?

Wine is a living product that is particularly sensitive to temperature variations. When temperatures become too high, wine evolves more rapidly and can lose its aromatic balance.

Excessive heat can cause :

• premature aging of the wine
• alteration of aromas
• accelerated oxidation
• deterioration of corks
• loss of freshness and balance

Temperatures above 20°C over a long period become particularly problematic for bottle conservation.

What is the ideal temperature for storing wine?

The ideal temperature for storing wine is generally between 10°C and 14°C. Stability is more important than temperature.

Sudden variations in temperature tire the wine and accelerate its evolution. A wine cellar enables you to maintain a stable temperature throughout the year.

Is it possible to store wine in a house or apartment in summer?

Yes, it is possible to store wine without a wine cellar during the summer, but only for a short time and under the right conditions.

Some rooms in the house are more suitable than others, especially those that are cool, dark and not very exposed to temperature variations.

However, it is not advisable to store bottles for long periods in rooms regularly exceeding 20°C.

Where to store bottles in summer without a wine cellar?

To limit the risks associated with heat, it's best to store bottles :

• in a cool, dark room
• away from direct light
• away from heat sources
• in a stable location with little temperature variation

A laundry room, storeroom or natural cellar may offer better conditions than a kitchen or living room with high exposure to heat.

Should I avoid certain rooms in summer?

Yes, some rooms are particularly inadvisable for storing wine in summer:

• very hot garages
• kitchens close to cooking appliances
• verandas
• rooms exposed to strong sunlight
• attics

These spaces often experience sharp variations in temperature that are incompatible with good wine conservation.

How long can wine be stored without a wine cellar?

It all depends on the type of wine and the storage conditions. For quick consumption, a few weeks or months can be envisaged if the bottles are kept in a relatively cool room.

On the other hand, for aging wine or storing valuable bottles, a wine cellar is highly recommended to guarantee stable conditions over the long term.

Is a refrigerator a good solution?

The fridge can be used temporarily to cool a bottle before tasting, particularly for white, rosé or champagne wines.

On the other hand, it is not an ideal solution for long-term wine storage. The air is often too dry, and compressor vibrations can affect bottle quality over the long term.

Why is a wine cellar the best solution?

A wine cellar enables you to recreate ideal storage conditions thanks to :

• a stable temperature
• controlled hygrometry
• protection from light
• reduced vibrations

It protects bottles from the heat of summer, preserving the wine's aromas and potential over the long term.

How do you protect your bottles during a heatwave?

During hot spells, there are a few precautions you can take to limit the risks:

• avoid sudden changes in temperature
• store bottles lying down
• close shutters to limit heat
• place bottles in the coolest room in the house
• avoid exposure to the sun

These solutions are only temporary, however, and do not replace a real wine cellar.

Frequently asked questions

Can wine withstand heat?

Wine can withstand a rise in temperature from time to time, but prolonged exposure to heat can alter its aromatic qualities and accelerate aging.

Can wine be stored at room temperature?

Yes, for a short period of time, provided the temperature remains relatively stable. Too high a temperature is not recommended, however.

What's the best room for storing wine in summer?

A cool, dark, stable room such as a cellar, natural wine cellar or laundry room is preferable.

Is a wine cellar essential in summer?

A wine cellar is the most effective way of keeping bottles in good condition over the long term, especially during the hot summer months.
