Guido Serio and his wife Isa arrived at San Fabiano in 1983 and immediately made investments aimed at producing quality wines. They have gradually made progress over the time, renewing the vineyards, the wine-making chain, the bottling and the cellar for refining the wine in wooden barrels.

San Fabiano Calcinaia produces wines appreciated all over the world: Chianti Classico vintage, Chianti Classico Riserva "Cellole", Cerviolo Rosso Igt, Cabernet sauvignon Igt, Casa Boschino Igt, Cerviolo Bianco, a small production of the traditional Vin Santo of Chianti Classico, and of Grappa of Chianti Classico "Cellole"; as well as, of course, the perfumed and fragrant extra virgin olive oil.

The farm of San Fabiano Calcinaia is located among the hills of the prestigious Chianti countryside. The farmhouse and cellars are part of a small medieval hamlet dating back to around the year 1000 A.D. nearby the towns of Poggibonsi and Castellina in Chianti.
