For the wine enthusiast hopefully still in the design stage of their homes, the Spiral Wine Cellar may be the solution to keeping the conditions right for long term wine storage. The Cellars were designed in 1978 by a Frenchmen who realized that most modern homes had no significant place to store wine in the proper conditions that the earth and its constant temperature can provide. The Spiral Wine Cellars are concrete wrapped in a water tight lining and passive ventilation keeps the temperature around 55Â°. As you might expect these babies aren’t cheap costing around $30,000 for materials and installation, but you only live once and wine make living so much better. Various sizes available to hold 1000 to 1600 bottles.
