In one of the highest hills of the Municipality of Gavi stands the Piona winery.
Piona is one of the historical areas of the Cortese vine: its southern exposure, a marl soil and a particular microclimate are ideal characteristics for a reduced grape production but for a quality wine.
The vines are trained in guyot in a current area of 4 hectares and are cultivated with the wisdom of rural tradition, respecting nature and men.
Currently they are produced a Gavi DOCG and a Gavi DOCG del Comune di Gavi
