Chianti Classico San Lorenzo takes its name from the lovely valley that is home to the 18th-century Pianigiani and Ricucci villas. The wine is made entirely with grapes from Castello di Ama vineyards, which are all old plantings or plots planted over a decade ago, and which show the most mature, rounded extracts at time of harvest. The Gran Selezione label was a significant step for the Chianti Classico designation, representing the top of the quality pyramid. Wines in this category are a guarantee for the consumer, in terms of origin and of quality. The production protocol states that all grapes must be produced by the winery itself and the wine goes on sale 30 months from harvest.
