In the recent past, there were far more white grape varieties planted in the Priorat than there are currently – only 5.5% of total plantings as of January 2017. Such is the case at Mas Alta, where old vines of Garnatxa Blanca, Pedro Ximénez, and Macabeu are scattered in their vineyards. Since 2008 Mas Alta has been resurrecting the tradition of white wine production in the village of La Vilella Alta by grafting over some of their Cabernet Sauvignon vines with a massale selection of their heirloom white varieties. Artigas Blanco is a blend of Garnatxa Blanca from young vines blended with 40-year-old Pedro Ximénez, Macabeu, and occasionally Carinyena Blanca. It is fermented and aged in a combination of new French oak barrels and stainless steel tanks.
