In Monterrei DO there is a mixture of local and regional grape varieties. White grape varieties are dominant, especially Doña blanca, Treixadura, Verdello, Caíño blanco and Godello. Of the small proportion of red grapes, the most common is Arauxa (the local name for Tempranillo), Mencía and Bastardo.
As most vineyards have been planted recently, they are on trellises (en espaldera) so as to maximise their exposure to the sun
