Cortese is a white grape variety native to southern Piedmont, originating in the Tortona hills and the Alessandria area. Its presence has been documented since at least the 17th century, and a detailed ampelographic description appears in 1798, by which time it was already known by the Piedmontese name Corteis. Over time, it has spread mainly across the Gavi, Novi, Tortona and Alto Monferrato areas, finding favourable conditions also in certain parts of the Asti, Cuneo and Oltrepò Pavese regions. The leaf is generally medium or medium-large in size, orbicular or pentagonal in shape, and often five-lobed. The bunch is medium-large, conical or pyramidal, sometimes with one or two wings; the berries, medium-sized and slightly oval, take on a golden-yellow hue when ripe. It thrives in breezy hillsides and marly, clayey and calcareous soils, which bring out its fruitiness and freshness. The wines are straw-yellow in colour, often with greenish highlights, and offer delicate aromas of white flowers, fresh fruit, citrus and almonds, accompanied by a balanced structure, pronounced acidity and a dry finish. In the more mature versions, mineral nuances and greater complexity emerge: Gavi Riserva can develop remarkable longevity, whilst retaining its elegance and tension. Cortese is also the star of still, semi-sparkling and sparkling wines, reflecting its versatile winemaking potential.
