Petit Rouge is a native grape variety of the Aosta Valley, historically associated with the Oriou family and documented in the writings of Lorenzo Francesco Gatta, published in 1838. The name derives from the French translation of the ancient dialect terms ‘Picciou rouzo’ and ‘Oriou picciou’, referring to the small size of the berries. The leaf is medium-sized, three-lobed or slightly five-lobed, with a slightly tomentose underside; the bunch, of medium or small-to-medium size, is truncated-pyramidal in shape, with one or two wings and generally of medium density. The berries are small, round and uniform, with a thin, tender and intensely pruinose skin, bluish-red or purplish in colour; the juice is colourless or very lightly coloured. Cultivation is concentrated along the Dora Baltea, from Saint-Vincent to Avise, on both sides of the valley, in hillside and mountain vineyards. Whether as a single variety or blended with other local varieties, Petit Rouge is the star of several wines within the Valle d’Aosta appellation, including Torrette, Nus and Enfer d’Arvier. The wine has a bright ruby-red colour, sometimes tending towards garnet, with vinous and fruity aromas of small red berries, possibly with hints of dog rose. On the palate, it is smooth, velvety, fairly tannic and full-bodied; it is generally best enjoyed young, though the more ambitious versions show interesting potential for ageing.
