The Tempranillo Blanco vines are grown in a small number of vineyard sites to the north and northeast of Viana, situated northern bank of the River Ebro. The vineyards are located on slopes ranging from 520 to 690 metres above sea level, which have been formed by small streams running down from the Sierra Cantabria hills, the terrain is uneven with ravines and the occasional small cliff. The vines are sheltered from the harsh northern winds and the wetter, cooler weather fronts by the nearby Sierra Cantabria range. The south facing orientation optimises sunlight exposure and warm, dry winds from the south help to ventilate the vineyard, reducing disease pressure. The vineyards are situated on a variety of soil types from sand, gravel, clay and chalk over a limestone subsoil. The topsoil is shallow, just 25 to 40 centimetres deep and as such, the vines take time to develop and establish complex root systems, and these bush vines are old and low yielding. The locals are reluctant to uproot old vine stocks and therefore these vines are noticeably older than those in the surrounding area.
