Compañía Vitivinícola Tandem


Compañía Vitivinícola Tandem was founded in January 2003 by Alicia Eyaralar, José María Fraile and a small group of wine-loving relatives and friends.

After extensive careers in winemaking and marketing, first together and later separately in different wineries, there was a growing interest in starting up Tandem. Tandem means “at last” and represents the aspiration of its two partners and promoters, to fulfil a dream and the mission which they have taken upon themselves.

sincerity and effort

our misiOn

Our mission is to make great wines through our hard work and dedication and to make Tandem a reference point for quality in the Navarra DO. 
We work with all sincerity and sparing no efforts to be very constant in each vintage, thinking only to improve and to project confidence.

Our pledge is to follow the path that we have set out upon, a different path from the rest, which is committed to respect for nature, meticulous care in everything we do and working with the least intervention possible. All this with the aim of making wines that are elegant and have personality, and which express the character of the land that gives rise to them and also attain our customers’ complete satisfaction.

In the vineyard and in the winery we implement a philosophy of minimal intervention. We rely on the most advanced and in turn simplest technology because we believe that in winemaking the less we intervene, the resulting wines turn out more authentic, natural, pleasant and expressive. Convinced that nature should follow its course and wine manipulation should be kept to the minimum in order to achieve authenticity.

We call it the ‘Tandem paradox’ because we produce wines considered modern using up to date technology which replicates how wines used to be made centuries ago:

  • The wines are moved by gravity in the winery.
  • We do not use a mechanical system for pumping over during fermentation.
  • We keep the red wines in underground concrete vats for a minimum of two years in order to clarify them naturally.
  • We do not use cold stabilisation.
  • Minimal filtration

¿Por qué somos tan raros que nos gusta esto de los vinos con edad? ¿Qué tiene de bueno un vino con más de 12 años? Al principio de mi vida en esto del mundo del vino un muy experto me dijo de forma clara que todos los vinos de más de 6 años estaban oxidados, no se podían beber. A pesar de eso mi empeño personal y, sobre todo, abrir muchas botellas viejas me ha hecho ver las cosas de otra manera.
