Catarratto Bianco produces medium-sized, pale green-yellow grapes with a thick skin. Wines made from this variety are usually light in color and body with aromas of white flowers and citrus fruits. On the palate, Catarratto Bianco wines have a pleasant acidity and minerality with subtle flavors of peach and apricot.

Catarratto Bianco is widely planted and used for IGT wines in Sicily, notebly in the west coast of the island. It is permitted in Alcamo and for Etna DOC wines. Catarratto Bianco is a vigorous variety, meaning it requires careful pruning and moderate yields to produce quality wines. The grapes are usually harvested in late August, and the wines are often blended with other varieties like Grecanico and Inzolia. The single varietal Catarratto wines are gaining popularities in recent years among winemakers. Catarratto Bianco wines are produced in both dry and sweet styles. In Marsala, it is also used as a key ingredient for the famous fortified wine. Catarratto Bianco wines pair well with a wide range of food, thanks to its neutrality.
