Milanese businessman Guido Serio bought San Fabiano estate in 1983. The vineyards are located in the historic Chianti Classico commune of Castellina, while the manor house and the cellar, which are part of the 10-century-old medieval hamlet, stand right on the south-western border of Chianti Classico denomination. The estate is essentially an agricultural enterprise, with grain fields, vineyards, olive groves and woods dispersed on 165 hectares. The vineyards currently occupy 42 hectares, 28 of which are planted around San Fabiano hamlet and the rest are in the locality of Cellole near Castellina.
Since the purchase of the estate Guido Serio made a considerable investment both in vine growing and wine making. The property had an old vinification cellar – it was promptly expanded and new modern equipment installed in mid 1980s. A vast new aging cellar was built in 2003. In between these years all vineyards were gradually renewed. Small replanting is still carried out each year, so the majority of today’s vines are aged 5 to 15 years. Franco Campanelli is a full time in-house winemaker, while Carlo Ferrini, a famed Tuscan enologist, followed the estate since 1984 and continues to work as a consultant.
