The first study for monovarietal planting in the Douro region was conducted in Quinta Nova de Nossa Senhora do Carmo, between 1979 and 1981, in conjunction with the Portuguese Ministry of Agriculture, through the Centro de Estudos Vitivinícolas do Douro (Douro Winemaking Studies Centre). In the study, the best solar exposures were chosen in Quinta Nova to study the planting of three grape varieties: Tinta Roriz, Touriga Nacional and Touriga Franca.
The Parcela29 (Plot), planted with Touriga Nacional, has 3300 vines, a slope of 20%, and an altitude between 170 and 205 metres. It represents a unique wine and a fundamental piece in the history of Quinta Nova de Nossa Senhora do Carmo in its maximum expression of terroir. A genuine Referência (reference) that combined with century-old vines (Plot 21), results in a wine with a very elegant profile, almost feminine, contrasting with an intense structure of juicy tannins of an enormous precision. A schist texture of high gravity, the savoury profile, and the purple colour reflects the nature of the Touriga Nacional variety.
