In Catalonia a couple of Italian immigrants are pushing their Spanish neighbors into organic farming and restoring native vines. Interestingly though their "TN" is a blend of Cabernet Sauvignon and Petit Veridot, grapes that migrated to the area from Bordeaux. All organic farming and made without sulfites.
From the mouth of the importer (Sev Rovine):
"The name Partida Creus is a reference to the crosses used for separating holdings back in the day. Massimo Marchiori and Antonella Gerona are an Italian couple from Piedmont. Both of them architects who initially moved to Barcelona for that reason. Around the year 2000, they moved out to the country in search of a “slower” lifestyle. They settled in the Massís de Bonastre (Baix Penedés) characterized by its clay and limestone soils. There they started farming all kinds of local foodstuffs but had trouble finding wines made in the same style so they started making their own, recovering old vines of local grape varietals."
