The white grape variety comes from Portugal. Synonyms are Veozinho Verdeal and Viozinho. According to DNA analyses carried out in 2018, it comes from a presumably natural cross between Savagnin Blanc (Traminer) x unknown partner. The early-ripening vine is moderately susceptible to fungal diseases such as powdery and downy mildew and botrytis. It produces aromatic, acidic white wines with ageing potential, also known as "Portuguese Sauvignon Blanc". The variety is mainly grown in the Douro, Península de Setúbal, Tejo and Trás-os-Montes areas, as well as in the Alentejo and the Azores. It is used, among other things, in blends with the Rabigato and Gouveio (Godello) varieties in white port wines. In 2016, a total of 916 hectares of vineyards were designated (Kym Anderson statistics).
