The sixth underground room of the itinery of Pozzo della Cava is a medieval wine cellar.

An Etruscan cistern was cut into for the staircase of this cellar; the stairs have the typical "scendibotte" or ramps on either side so that the barrels could be rolled down to the room below.

Don't forget that many of the cavities in the subsoil of Orvieto have always served as wine cellars, for they have the three fundamental characteristics needed for the conservation of the famous Orvieto wine: a constant temperature, darkness and silence.
