Tandem is the brainchild of José Maria Fraile and Alicia Eyaralar, two of the leading lights in the Navarra winemaking scene. Committed to making the best wines in the region with minimal intervention in the vineyards and winery, Tandem is cited by critics as ‘cutting edge’ Navarra. The grapes are cultivated in the heart of the Yerri Valley, which is recognised as the best area for quality wine in the region. Respect for nature is an obsession – they follow the precepts of sustainable viticulture, while maintaining the vineyard’s health and viability. In the winery, a minimum intervention approach is also taken to ensure the grapes reflect their true character and terroir. In 2019, the winery was certified Vegan and accredited the internationally recognised ‘V label’ by the European Vegetarian Union.
