Viosinho

Viosinho is a high-quality white-wine grape variety from northeastern Portugal. It has been found in vineyards in the Douro and Tras-os-Montes regions since the 19th Century.

Viosinho is not usually produced as a varietal wine, largely due to it being most commonly planted in mixed rows alongside other white wine varieties. It is typically used in white ports and, increasingly, blended white wines.
