Welschriesling probably origins from northern Italy, where it is known as the Riesling Italico. The closest relative is Elbling. The variety is also cultivated in Hungary (Olasz Rizling), Slovenia (Laski Riesling) and Croatia (Graševina).
Parentage
Unknown. Elbling is the most closely related variety. Welschriesling is not related to Weisser Riesling.
Vineyard area
The versatile Welschriesling can produce almost all quality levels. Grapes from the Poysdorf area in the Weinviertel are commonly used in base wines for neutral, more acidic styles of Sekt, while this variety also produces easy-drinking Buschenschank tavern wines in Steiermark and nobly sweet Trockenbeerenauslese wines in Burgenland, particularly around the Seewinkel area. The variety’s total area under vine decreased significantly between 1999 and 2020.

Significance & conditions
These grapes are very good for producing Sekt, and can also deliver some outstanding Prädikatswein. The range of quality is very wide. To thrive, Welschriesling requires early-warming vineyards and soils with an ample supply of magnesium. The vines are very sensitive to dryness – too little moisture can cause inadequate shoot development.

Characteristics of the wine
Yields wines with a higher acidity. Dry Welschriesling wines are often very fresh with aromas of green apples and citrus. However, winegrowers have recently begun producing complex wines with good ageing potential by maturing them on the lees for a longer period of time. Prädikatswein made with this grape variety are considered to be some of the world’s greatest sweet wines. Beerenauslese and Trockenbeerenauslese both have exotic aromas in their bouquet and delicate notes of honey on the palate, underpinned by a characteristic level of acidity.
