Sauternes are unbelievably robust wines, yet some rules must be followed: They are to be stored in a cellar. It should be (buried, clay soil, stone walls), with few temperature variations (ideally between 10°C and 13°C, with a variation + or – 3° to 4° C.).

There must be proper ventilation and a constant hygrometry between 70 and 75%. Temperature has an influence on wine development and ageing.

A cellar that’s too humid will cause excess mold, which in turn destroys cork, thus producing a bad taste in the wine. And for those who like labels, please note that labels suffer!
Your bottles are treasures… respect them!
They need darkness and calm and should not be handled too much.
Do not store them in cardboard boxes. Wooden cases reduce humidity. Store them on horizontal shelves providing permanent contact between the wine and the cork, without which your wines will be in danger of oxidation.
If you do not have a natural cellar, today you can buy wine-cellars whose temperature and humidity remain constant and wherein wines are stored horizontally. In this type of wine-cellar, you can store the wines that you are going to enjoy in the next 2 or 3 years and ask for a space in a proper cellar for those that you wish to age for several years!

Stored in this way, you will be able to taste with pleasure and emotion vintages able to mature for 20 or 30 or even 50 years expressing such surprising youth.
