It was created in 1963 by József Csizmazia Darab and László Bereznai by crossing the hybrid Seyve-Villard and Bouvier. Its original name was Egri Csillagok 40. It gained state certification in 1982, when it was given the name Bianca. The story of the choice of name can be traced back to a close friend of the breeder, who referred to Joseph Csizmazia's wife Blanka as Bianca.
The variety can also be found outside Hungary. For example, it is cultivated on 2,700 hectares in Russia and sources report vineyards in Switzerland, The Ukraine and China, too. It is also registered in Austria.
There were only 2,320 hectares of the variety in Hungary in 2010. However, this has now grown to 5,340 hectares and it is cultivated in almost all wine regions, albeit in very small quantities. It is the most planted variety in the Kunság wine district, where there are 5,100 hectares, followed by the Hajós-Baja wine district, where it accounts for 6% of the vineyard area.
It is an aromatic variety which yields light, fresh white wines. Wine style is greatly influenced by the time of harvest, as it drops acidity very quickly and loses its original aromas when overripe. It is also prone to oxidation, thus wines require reductive winemaking technology. Besides floral notes, the wines can boast a truly unusual range of aromas and flavours. It is often blended with other varieties and rarely made as a PDO wine.
