Annually in Tivoli is celebrated the Festival of Pizzutello. The first festival of Pizzutello and wines was held in Tivoli on 2 October 1845, for the visit of Pope Gregorius XVI, who came to check the status of construction of tunnels in Catillo mount for the deviation of the Aniene river.
On this circumstance the tiburtine people organized many decorations with wines, Pizzutello grape, Pergolese grape which were placed along the streets.
Pounds and pounds of pizzutello were used to decorate a boat that the tiburtine people offered to Pope Leo XIII (1878-1903).
In 1932 Tivoli participated to the National Festival of the Grape and won the first prize. In 1933 was officially instituted the Festival of Pizzutello: allegoric wagons were constructed by the tiburtine people and brought for the ways of Tivoli. Then the wagon most beautiful was sent to Rome for the National Festival of the Grape.
