The vines are planted using the Guyot training system, with a plant density of 6,200 vines/ha. (2,500/acre) and a yield of no more than 1.2 kg. (2.65 lbs.) per vine. The vineyards are designed so as to fit perfectly into their surroundings: the vines are supported by wooden stakes at the head of each row, and by galvanized iron posts along their length. An irrigation system exists, but it is only used in periods of extreme drought.
The soil in this area is limestone-based: it is very fertile and permeable, as well as being cool and a reddish ochre in colour due to its iron content. The slopes and the subsoil display phenomena caused by erosion such as the caverns at Castellana in the Province of Brindisi and that of Zinzulusa near Otranto.
