BACK IN. Single Estate red from the Obidos region. CastelÃ£o (60%), Aragonez (20%),Touriga Nacional (20%) are aged for 12 months in French and American oak barrels. This was my pick of the family’s three estate wines. Maybe it’s the Touriga Nacional which gives it an almost violet fruit over and above the soft, oakiness. It has won Gold at four separate competitions this year.
