WINE STORAGE AND WINE CELLAR The traditional way to store wine is making underground caves, in which temperature is relatively low and no much ventilation. Nowadays, residential and commercial wine cellars are common. Temperature and humidity are the two essential factors which govern proper wine storage at their best quality. Many people ask whether I still in need of a dehumidifier although I already have a cooling device. You cannot invest in equipment to keep your wine cellar cool without thinking about how to make sure it's also adequately humid.
