ES: A fines del siglo XIX surgen las marcas comerciales modernas, después de la creación del marco legal para su protección y el nacimiento de grandes empresas comerciales. En el sector vitivinícola portugués hubo una fuerte adhesión de las empresas al re-gistro de marcas como defensa contra las prácticas de “uso indebido de indicaciones de procedencia falsas”, en un contexto de conversión postfiloxérica, de un mercado inestable  y  la  proliferación  de  imitaciones  y  falsificaciones.  El  sector  comercial  se  apropiaría de la marca en su identificación con la Denominación de Origen, lo que llevó  a  la  aparición,  a  principios  del  siglo  XX,  de  un  movimiento  liderado  por  las  élites de la Región Demarcada del Duero en el sentido del reconocimiento y defensa legal  de  la  marca  regional  Porto.  En  este  artículo  nos  centraremos  en  tres  fincas  históricas  —Senhora  da  Ribeira,  Bomfim  y  Zimbro—  y  en  las  marcas  comerciales,  etiquetas y marcas de fuego de Silva & Cosens, una de las compañías de comercio de vino del Duero más respetadas a principios del siglo XX. Intentaremos comprender cómo la compañía creó marcas comerciales con una fuerte identificación con la Re-gión Duriense, la región que produce sus vinos.Palabras clave: vino de Oporto, marca comercial, Denominación de Origen, Región Demarcada del Duero.Introduction In the Alto Douro region, the oldest demarcated and regulated region in the world, with shale soils,  vineyard  cultivation  dates  to  Roman  times,  having  developed  progressively  in  the  fo-llowing centuries. From the 11th to 13th centuries there was an expansion of the vineyard. And as soon as the 17th century, English, Flemish and Dutch traders settled in Oporto, dedicating themselves to the export of Douro wines.While the export of wines to England increases, the first conf licts between producers and mer-chants erupt, leading to the Constitution of the Companhia Geral da Agricultura das Vinhas do Alto Douro by Royal Charter, in 1756, accompanied by the demarcation of the producing region (see Pereira, 1996: 180-188; Pereira, 2010b: 10-16). The  law  of  7th  December  1865,  the  result  of  an  intense  and  prolonged  debatebetween  free  traders  and  protectionists  on  the  wine  sector  issue,  established  a  regime  of  freedom  of  trade  that would end only in 1907. During this period, all regulatory mechanisms were abolished: the demarcation was eliminated, as well as the restriction of the port bar of Porto for the export of Douro wines and the supervision and certification of wines.At the end of the 19th century, modern commercial brands emerged after the creation of the legal framework for their protection and the birth of large commercial companies. On the other hand, the commercial sector would eventually take ownership of the brand, na-mely  in  its  identification  with  the  designation  of  origin,  leading  to  the  emergence  at  the  be-ginning  of  the  20th  century  of  a  movement  led  by  prominent  landowners  and  personalities  from the Douro Region aiming to recognition and creation of legal mechanisms to defend the regional brand of Porto.
Abstract (EN): 
At the end of the 19th century, modern commercial brands emerged after the crea-tion of the legal framework for their protection and the birth of large commercial companies. In the Portuguese wine sector, there was a strong adhesion of companies to  the  registration  of  trademarks  as  a  defense  against  practices  of  “abusive  use  of  false  or  misleading  indications  of  provenance”,  in  a  context  of  post-phylloxera  re-conversion, market instability and the proliferation of imitations and counterfeits. The  commercial  sector  took  ownership  of  the  brand  in  its  identification  with  the  designation of origin, leading to the emergence at the beginning of the 20th century of a movement led by prominent personalities from the Douro Region in the sense of creation of legal mechanisms to defend the regional brand of Portwine. We will analyze three historical quintas (estates) — Senhora da Ribeira, Bomfim and Zimbro — and the marks (brands, labels and fire marks) of Silva & Cosens, the “most respec-table” company in the Douro wine trade in the early 20th century. We aim to undes-rtand  how  this  company  created  trademarks  with  a  strongly  identifying  character  with the Douro Demarcated Region, the producing region of its wines.
