Boca is a historic wine-growing area in Upper Piedmont, situated on the hills of the province of Novara at altitudes of between 300 and 550 metres. The vineyards occupy sunny, well-exposed slopes, whilst the land in the valley floor is excluded in order to preserve conditions favourable to ripening. The terroir is characterised by a complex matrix of moraine and alluvial deposits, comprising clay, sand, silt, granite pebbles, porphyry and fragments of dolomite rock originating from the Fenera massif. The presence of cool northerly breezes and the natural protection afforded by Mount Fenera foster significant daily temperature variations, alongside mild winters, temperate springs and bright summers and autumns.
The grape variety composition is dominated by Nebbiolo, locally known as Spanna, alongside Vespolina and Uva Rara, also known as Bonarda novarese. The result is a red wine with structure and vigour, characterised by refined aromas, a balanced tannic profile, savoury notes and evolving characteristics. Traditional winemaking practices preserve distinctive local heritage, such as the horizontal terraces built along the contour lines and the dry-stone walls. The winemaking process involves a long ageing period, including in wood, which complements the natural ability of Boca’s wines to develop complexity and harmony over time. Local viticulture boasts ancient origins and a historical continuity recognised by the DOC designation, established in 1969.
