Wine can be stored for a long time. This is not true of all wine, but true quality wine actually gets better with age. It is estimated that around 4 per cent of all wines in the world get better with age. Many Burgundy wines fall under that 4 per cent. Storing wine – also known as ‘layering’ – is quite common in Burgundy. Some winemakers do not release their cuvées for years. Others recommend not drinking their young wines yet but preserving them, as they only reveal their character after years. Burgundy wines can therefore generally be kept for a long time. A Grand Cru can be stored for 20 years just fine. But this must be done properly. What should be borne in mind when storing wine?
Temperature
Storage temperature is one of the most important factors in maintaining wine quality. The ideal temperature for storing wine is between 12°C and 16°C. It is important that the temperature remains stable and fluctuates as little as possible. Large temperature fluctuations can negatively affect the taste of the wine. Some winemakers talk about storing at room temperature. Know that this refers to the room temperature of yesteryear. About 16 to 18 degrees. And thus not the temperature we are used to inside these days.
Humidity
The humidity level of the storage area is another important factor in maintaining the quality of the wine. The ideal humidity level is between 60 and 80 per cent. An environment that is too dry can cause the cork to dry out and shrink, allowing air to enter the bottle (oxidation). An environment that is too humid can cause mould on the cork and affect the label. The storage area should also be ventilated to ensure healthy air flow. This prevents the air in the room from becoming too humid and causing mould.
Light
Wine should be stored in a dark place, as light can affect its quality. UV rays can oxidise wine and alter its flavour. Therefore, wine should be stored in a dark environment, away from direct sunlight.
Stable position
Movement can also affect the quality of wine. So don’t put wine on or next to a washing machine, for example. Also, wine should be stored horizontally so that the cork stays moist and does not dry out. This prevents air from entering the bottle and oxidising the wine.
Fragrances
Wine should be kept in an environment free of strong odours. For example, the smell of paint, detergents or solvents. This can affect the taste and aroma of the wine.
A climate cabinet helps in storing wine. In this cabinet, temperature and humidity are regulated and constant. But a climate cabinet costs energy and is often limited in space, especially when a collection takes on serious proportions. A dark cellar with a stable temperature (still very popular in Burgundy), is still the perfect solution.
