A native of Galicia, Gutier Seijo Otero developed his own project, Mix and Mixtura, in 2019 after nearly a decade at the helm of the historical Ribeira Sacra winery, Dominio do Bibei. Though his winery is in Ribeiro, the project is focused on recovering historical vineyards and native grape varieties in northwestern Spain and Portugal along the Miño and Sil rivers. His wines disregard traditional political boundaries and are labeled without appellation and variety. The project is rooted in a deep respect for the land and culture, using minimal intervention and native yeasts, with Mix largely vinified and aged in small old French oak and Tava amphoras, and Mixtura in concrete eggs and Stockinger barrels.
