The Spiral Cellar system was developed in 1978 by a Frenchman
who saw that few modern houses had wine cellars, but that
people still needed a place to store their wine.  If a wine-
lover has a serious collection it can quickly outgrow wine
racks and refrigerator units.  So he came up with the Spiral
Cellar design, which uses the earth to insulate and create
good storage conditions.  It does this, however, in a fraction
of the space of a regular cellar.  It also can maintain a
constant temperature with no power required.

A spiral cellar is dug into the floor by a professional team,
and the cellar storage itself is created from concrete wrapped
in a watertight lining.  Passive ventilation keeps the temper-
ature around 55°, an ideal temperature for wine storage.  There
are several sizes, holding from 1000-1600 bottles.

Of course, this is one indulgence for wealthy or well-off wine
drinkers only.  The Spiral Cellar purchase and installation
runs at least $30,000.
