Notes from the Piedmont Guy:

"Erbaluce is an autochthonous grape variety that has adapted to the morainic soils of the territory, a subalpine zone known as the Canavese, which is centered on the town of Caluso. 

In 1977, when he was 16, Bruno convinced his father Giuseppe to vinify Erbaluce using only natural yeasts and without skin contact, which stood in stark contrast to the common approach of producers in the zone who left the must to ferment on the skins. This innovative style of Erbaluce was bright, fresh, and different from anything the winery had produced theretofore."
