History archeology and legends weave together to explain the pleasure of this wine that has been actually required as payment. It is proved by the agreements signed in 1496 between the Opera del Duomo di Orvieto and Pinturicchio that allowed to the painter six “quartenghi” of wheat per year ... and the required wine. Luca Signorelli, to realize the Chapel of San Brizio frescoes, required to the Opera del Duomo an yearly payment of 12 measures of wine (about 1000 liters).
