However, the region has showed its great potential throughout the years thanks to an exceptional combination of soil, climate and varieties. It is the only winegrowing region in Galicia whose territory lies along the Duero riverbank, although it is still subject to the oceanic influence of the other regions, which is a guarantee for the cultivation of red varieties. Monterrei shares the cultivation of local varieties with the neighbouring regions: Godello with Valdeorras, Treixadura with Ribeiro and Mencía with Ribeira Sacra.
Since the nineties, the land within this region has been reclaimed by growing local varieties, boosting a wine sector that currently includes 371 winegrowers and 23 bodegas.
Within the wide variety of soils found in the region of Monterrei, Pazos del Rey employs granite-clay soils for the Godello variety (Pazo de Monterrey Godello) and poor, shallow, sloped land with sandy-clay soils and a slate and schist base that enhance the aromas of the Mencía variety used in Pazo de Monterrey Mencía.
