Tuscany is a region of large estates, but even in such context Barbialla is notable for its expansiveness. Close to 2,000 acres (800 hectares) in size, the estate sprawls over a territory in which three historic Tuscan provinces come together and join. Barbialla is at the extreme western edge of the province of Florence. Just to the north lie the township of San Miniato, a fortress town in the lower Arno valley. To the south, is San Gimignano, home to an impressive number of perfectly preserved towers which attract, in addition to the fine wine and the surrounding saffron fields, hundreds of thousands of visitors each year. Pisa is 48 miles (77 kilometers) to the west of the estate and Siena virtually at the same distance to the south.
