Region – Ghemme, Piedmont, Gaudenzio Fontana and Carlo Platinetti, grandfather and great-grandfather respectively of the current heirs of the company, began growing vines in the early 20th century, in the best-suited areas of Ghemme (Baragiola, Val Maiolo, la Rosa and Ronco al Maso). In particular, Gaudenzio, born in 1889, after taking part in the First World War, vinified grapes - from the 1920s to the 1950s - from his vineyards in his own wine cellar in Via Interno Castello, in characteristic Ricetto di Ghemme. In the first half of the 1970s, Gaudenzio's son Mario set up azienda Agricola Platinetti Guido. They continued to cultivate the existing vineyards and planted the first steeply sloping parcels of land on the first hill towards the village.In this area, called Ronco al Maso, marked by excellent south-west exposure, it was possible to claim the new designation of origin for the wine produced: Ghemme DOC. These vineyards are still producing wine today. Over the years, the rooted vine cuttings of the original planting system have developed deep roots. These can penetrate several metres into the fluvial-glacial soil to search for nutrients andminerals, which, assimilated by vines, are released into the grapes and subsequently pass, year after year, into GHEMME DOCG Vineyard Ronco Maso wine.
