Welschriesling is a white wine grape variety, unrelated to the Rhine Riesling, that is grown throughout Southeastern & Central Europe. It has many synonyms, including Borba blanca.

The descendance of Welschriesling is uncertain. The German name Welschriesling literally means 'Romanic Riesling' (cf. Walhaz), and most of the synonyms in Southeastern & Central Europe are variations on 'Italian Riesling'. Welschriesling may have been brought to Central Europe by the ancient Romans. However, the Croatian name Graševina suggests that the origin might be somewhere to the east of the Balkans.

A modern theory claims that Welschriesling originated in the Champagne region and came as welsch (in this case French) Riesling via Heidelberg to the lands of the Austro-Hungarian Monarchy.
