Mostosa is a native white grape variety from Emilia-Romagna, also grown throughout the Adriatic regions down to Puglia, as well as in Lazio and Umbria. In the various regions where it is cultivated, Mostosa is known by several synonyms, including Pagadebit, Ascolana, and Scacciadebito. It has been registered in the National Register of Vine Varieties since 1971 and is included among the varieties of the Colli di Rimini DOC. The origins of Mostosa are unknown, but its popularity among growers is largely due to its high productivity, which is reflected in some of its synonyms. It is preferably cultivated on hilly, clayey-calcareous-sandy soils. Mostosa thrives in well-ventilated sunny exposures and is greatly influenced by coastal climates, which impart a certain salinity to the grapes.

The clusters of Mostosa are large, pyramidal or conical, moderately compact, and winged. The berries are large, spherical, with a pruinose skin of green-yellow color. The wine produced from Mostosa grapes has an intense straw yellow color, with floral and fruity notes. It is dry, fresh, with a full but light taste, and is not very structured. It is appreciated as an aperitif but also pairs well with broths, light first courses, fish, white meats, and soft cheeses. The recommended serving temperature is between 50-57°F (10°-14°C).
