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.
