The commune of Boca is home to the Denominazione di origine controllata (DOC) wine which includes 15 hectares (37 acres) producing a single red wine. The wine is a blend of 45-70% Nebbiolo, 20-40% Vespolina and up to 20% of Uva Rara (known locally as Bonarda Novarese). All grapes destined for DOC wine production need to be harvested to a yield no greater than 9 tonnes/ha.
