This was the very first wine we developed. It comes from the Tempranillo Blanco grape; this grape is a mutation from a single (red) Tempranillo vine that was found in 1988 in an old vineyard located in Murillo de Río Leza, La Rioja. Development of these grapevines was part of the Universidad de La Rioja minority varieties rescue project conducted by Professors Juan Carlos Sancha and Fernando Martínez de Toda. The Consejo Regulador of Rioja accepted this variety as an official grape in D.O.Ca Rioja in 2007. Our Tempranillo Blanco vineyard is ten years old. The white Tempranillo Blanco grape is 97% genetically similar to its red Tempranillo cousin. The leaves and grape cluster shape are identical; so also are their susceptibility to diseases and pests. Both have short, early-ripening cycles which enable these grapes to be grown in any subzone of the Rioja Domination and to complete their ripening even in zones where later ripening takes place. The Tempranillo Blanco vines have medium to high vigor and a medium yield (6,000 kg of grapes per hectare). The grape clusters, while abundant, are of small size and medium weight.
