German wine - wine basics
Storing wine
An ideal spot for wine is one that is cool, dimly lit, moderately humid, relatively quiet and where the temperature is a constant 50° to 55° F (10° to 12° C).
When such ideal conditions do not exist, the most important consideration is to find a place where the temperature does not fluctuate wildly. A quiet, cool spot such as a closet, hallway, unused fireplace, or space under the stairs will do. Warm places such as the kitchen or bright, light places such as near a window are not recommended. Wine should always be stored lying horizontally, so that the cork remains moist and elastic. Only wines with metal caps can be stored standing up.
[aging]
Do not store wine near goods that emit strong odors, because the wine "breathes" through its cork and has a tendency to absorb odors from the air.
