Trebbiano is one of the most widely planted varieties of grape in the world. It gives good yields, but tends to yield undistinguished wine. It can be fresh and fruity, but does not keep long. Its high acidity makes it important in Cognac and Armagnac productions. Also known as Ugni blanc, in particular in France, it has many other names reflecting a family of local subtypes, particularly in Italy and France.

Trebbiano may have originated in the Eastern Mediterranean, and was known in Italy in Roman times. A subtype was recognized in Bologna in the thirteenth century, and as Ugni blanc made its way to France, possibly during the Papal retreat to Avignon in the fourteenth century.

An Italian study published in 2008 using DNA typing showed a close genetic relationship between Garganega on the one hand and Trebbiano and several other grape varieties on the other hand. It is therefore possible that Garganega is one of the parents of Trebbiano, however, since the parents of Garganega have not been identified, the exact nature of the relationship could not be conclusively established.

During a series of trials between 1924 and 1930, Trebbiano was crossed with Gewürztraminer to create the pink-skinned Italian wine grape variety Manzoni rosa. Also, in the early 21st century, DNA analysis has suggested that there may be a close genetic relationship between Trebbiano and the Emilia-Romagna wine grape Alionza.

Like many Italian grapes, Trebbiano came to Argentina with Italian immigrants.

"White Hermitage" came to Australia with James Busby in 1832. The major plantings are in New South Wales and South Australia, where it is mostly used for brandy and for blending with other grapes in table wine.

It is known as 'Thalia' in both Bulgaria and Portugal.

'Ugni blanc' is the most widely planted white grape of France, being found particularly along the Provençal coast, in the Gironde and Charente. It is also known as 'Clairette Ronde', 'Clairette de Vence', 'Queue de Renard', and in Corsica as 'Rossola'. Most of the resulting table wine is unremarkable and is often blended or turned into industrial alcohol.
