One of the most under appreciated aspects of enjoying a good quality product is the way the wine is stored. Having your wine susceptible to changes in humidity and temperature is a sure fire way to opening up a bottle of Chateau Vinegar!
Constant temperature and relatively constant humidity will ensure that you are enjoying a wonderful wine even after years of storage. By constant we do not want wine stored in a place like a garage or even a vented cold cellar where the fall nights of 3 or 4 degrees are followed by warm days of 18-20 degrees. That is a recipe for disaster.
Keeping your wine under a basement staircase or in a closet where the temperature will be fairly constant and away from any direct heating or cooling unit will allow your wine to mature and be enjoyed for years to come.
