For optimal ageing potential, wines must be stored under ideal conditions, here I will try to mention some of the important factors to store wine in.
Wine should always be kept in a dark place, because light makes wine age faster, too much light can even make wine taste bad.
Wine should be kept in a moist place so the corks don't dry out. But be careful not to have a wet place, this can make the wine labels moldy or deteriorated.
Wine should always have a constant temperature, the best temperature is in a cellar, at about 12-13 degrees.
No vibrations and free of odors, like gasoline or petroleum, or whatever you think of keeping in the same room as your wine, keep in mind not to keep things with odors.
Okay just to sum this up.
A dark place, a bit moist with no other odors, at a room temperature of about 12-13 degrees, sounds simple? well these conditions can be hard to contain.
