wheat or grain
Although frumento is properly 'wheat', gran or grano (grain) is commonly used as well, and the Italians, naturally, are great connoisseurs; see also grano duro and farina. There is a movement in recent years to bring back historic varieties of wheat and spelt (farro). Grano saraceno is buckwheat; grano di caffé is a coffee bean.
