The wines of Altiero are lovingly crafted by molto gentile Paolo Baldini, who carries the tradition and name of his uncle forward, working the land and making the wines with his father Maurizio and a good amount of support from the family.
Grapes for the wines are sourced entirely from vineyards on their land, which are dotted around the gorgeous village of Montefioralle (near my recommended osteria Taverna del Guerrino). Most of the vines are youthful Sangiovese, though a few are 30+ years old and some Merlot is planted for his Burrasca single-varietal bottling.
Paolo is best known for his Chianti Classico Riserva, which he produces at most about 1,000 bottles. His normale Chianti Classico is pretty basic, but nice and a great value for what you get (it's about €8/bottle in Italy). If you are lucky enough to experience it, check out Paolo's Burrasca Merlot -- he produces only 600 bottles/year, so don't be surprised if he's out. Paolo also makes a very refreshing rosato (pink) wine that's easy drinking during the summer months.
