In Portugal, the wine grape is known as Doña Branco, and in Spain the variety is known as Doña Blanca (except in Valdeorras where it is primarily known as Valenciana) The grapes have thick skins, which does well in the wet maritime climate, but it can also impart some astringency and slight bitterness even with the briefest of skin contact during production due to the high proportion of polyphenols in the skin. |
