The 2005 Colorino di Casanova is the darkest and most powerful of these three wines. A dark, plush core of wild cherries, plums , underbrush, leather and licorice hides behind a wall of imposing tannins. The wine needs a few years for the elements to meld together, but there seems to be quite a bit of potential here as the wine opened up beautifully with some time in the glass. Sweet menthol, spice and mineral notes linger on the long, satisfying finish. This is a beautiful effort from Giorgio Rivetti. Anticipated maturity: 2011-2017. Although proprietor Giorgio Rivetti is best known for the wines he makes in Piedmont, his Tuscan offerings have come a long way in the last few years.
