The flagship wine consists of 100% Sangiovese aged in French oak barrels.  Over the years, Paolo has refined his Cepparello by giving it more air during vinification and increasing time spent in oak from 12-14 months to 18-20 months. Although De Marchi started focusing on the use of better quality oak around 1993, it is the increased age of the vineyards themselves that have given Cepparello its overall finesse. The wine is made from a top selection of the estate's best fruits from the vineyards in Barberino Val d'Elsa in the northern part of Chianti Classico.
