The return of Casaglia, the single-variety Colorino, an
ancient native grape variety found in Tuscany, which
has been farmed in the Tenuta for a long time.
Its name comes from the intense pigmentation of its
must which was often used with other varieties to
improve color and structure in Chianti blends.
Tenuta di San Donato produces it as a single variety
wine for a unique tasting experience.
