Colorino is a red Italian wine grape variety planted primarily in Tuscany. The grape is known for its deep dark coloring and is used primarily as a coloring agent in red blends. In the history of Chianti it played a minor role, mostly for its affinity and use to the governo winemaking technique. Like Canaiolo, Colorino did not rot easily while going through the partial drying process to later be added to the fermenting grape must. However the grape did not provide the same level of fruit and softening effect that Canaiolo did and fell out of favor. In the late 1980s, there was a surge of interest in the variety among Tuscan winemakers who saw in this local grape variety similarity to the role Petit Verdot plays in Bordeaux blends. Colorino was planted and used to add darker colors and structure from phenolic compounds in the grape’s thick skin without the overpowering aromatics that Cabernet Sauvignon could add. This enthusiasm was short lived and by the turn of the 21st century Colorino returned once again to a minor role in Tuscan wines.
