Gruaja is an ancient black grape variety from the Veneto region, linked to the winemaking tradition of the Vicenza area and also known by the synonyms Gruajo, Gruaio, Cruaia, Crovaja and Cruara. The earliest records date back to the 18th century, whilst the variety was described in greater detail in the 19th century, when it was grown in the areas around Bassano del Grappa and Marostica. Today, its main growing area is the Breganze hills and the foothills of the Vicenza region, where it thrives in well-exposed and well-ventilated locations.
The vine is of medium vigour and ripens late. The leaves are medium-sized, with a pentagonal shape and generally three- or five-lobed. The bunch is medium-sized, conical, with one or two wings and tends to be loose; the berries are medium-sized, spherical, covered in a generous bloom and characterised by a blue-black skin. Hardy and not particularly susceptible to the main grapevine diseases, Gruaja ripens best in hot vintages.
The red wine produced displays a bright ruby colour, sometimes with violet hues, and aromas of red fruits, small wild berries and delicate spicy notes. On the palate, it is fresh, lively and medium-bodied, with fine tannins and a pleasant touch of acidity. Its structure supports reasonable ageing in the bottle. The white vinification is also of interest, as it can enhance the wine’s freshness and make it suitable for sparkling wine production.
