SRC farms parcels in areas including Crasà, Barbabecchi, Calderara Sottana, Pirao and Rivaggi, spread around Castiglione di Sicilia and Randazzo. The vineyards sit at different elevations and on lava flows of different ages, giving each site its own identity.
Many vines are between fifty and one hundred years old and are trained in the traditional alberello style. Nerello Mascalese is central to the reds, sometimes joined by Nerello Cappuccio and Grenache, while Carricante and Grecanico form the base of the white wines.
