Pedro Jesús and Angel Lizarraga (father and son) are our viticultural partners. Their 22 hectares of vineyards in the Yerri Valley provide the basis of Tandem's quality mission. These 22 hectares are divided equally between Tempranillo, Cabernet Sauvignon and Merlot. The vines are on average 20 years old and are managed in exemplary fashion.

The combination of loam/clay soils, a favourable micro-climate within a severe continental climate, the right amount of rainfall and an altitude of 600 metres, all make for very healthy fruit in all the weather conditions that we have encountered up until now.

The vines are not irrigated which ensures a better expression of terroir in our wines.

Our philosophy is simple: to make great wines we need great fruit. We therefore work very hard in the vineyards all year round. Pedro and Angel personally work the vines with Alicia's supervision and spare no effort or expense in getting the best out of each vintage. Pruning, flowering, green harvesting as and when required and as many times as required etc.

During the months of September and October we carry out continuous tests to analyze grapes from each vineyard parcel to establish the moment of optimum ripeness. In addition to this controlled analysis we also make sure we taste the grapes to know when the harvest should begin.
