90% of the grape production comes from their own vineyards, some of them being more than 50 years old, which can be found in the parish of Castrelo, located in the Umia-O Grove Intertidal Complex (Red Natura 2000), in front of the island of A Toxa.
The vineyards are in lowlands very close to the sea with altitudes that range from 0 to 30 meters. The terroir has a sandy-loam texture and is therefore a loose soil with good water penetration capacity and easy drainage. The vineyard is trained in a system that is perfectly adapted to the area due to the high humidity, mild temperatures and high rainfall, which are well distributed throughout the year. The planting frame is 4×4 (about 1,200 vines per hectare).
