Origin: The Colorino of the Valdarno derives its name from the abundant present colour in the skin of the grape and not in the flesh, which is colourless. According to other authors (De Astis 1937; Breviglieri and Casini 1964) it is a native vine of Tuscany that in the forms less improved is similar to the wild grapevine. The Colorino could derive from the selection of some wild vine in the zone of the Valley of river Arno (Valdarno). In Tuscany two types of such vine are cultivated generally: that classical motto of the Valdarno, which has leaves and shoots in red, and another with non reddish buds and the grape somewhat less coloured. The first one has had greater diffusion, but now itís is at the risk of genetic erosion.

 

Agronomic and environmental aspects: Variety characterized by a medium and constant production. For a good production it wants forms of breeding to medium expansion. For this variety cases of incompatibility of graft have been shown for some rootstocks (Rupestris du Lot).

Diseases, pests and disorders: Medium resistant to the common pests and disease, but shows particular sensitivity to powdery mildew.

Wine characteristics:

In Tuscany the Colorino is losing its popularity, however is still used to blend Sangiovese in some famous Tuscan wine (at around 5-10% in most Chianti wines and 10-20% in the Vino Nobile of Montepulcino) and also in other DOC and DOCG. This variety gives to the blended wine an intense ruby-red colour, freshness and an attractive ripe red fruit taste.
