Frantoio Gradassi: A legacy of Umbrian olive oil excellence. In the heart of Italy, near the medieval town of Campello sul Clitunno, the Gradassi family has been cultivating olives for generations. Their commitment to quality begins with hand-picking the olives from their rocky terrain and continues with processing them in their historic olive mill, dating back to 1639. Frantoio Gradassi produces some of the most spectacular extra virgin olive oils in Umbria, embodying the warmth, simplicity, and authenticity of Italian tradition. They are also founders of CUFROL, supporting local olive mills.
