AB Portugal  is  a  country  traditionally  dedicated  to  viticulture  and  character-ized by the production of wines of high quality. It has been among the top of 15 coun-tries  in  the  sector  in  terms  of  vineyard  area  extension  and  wine  production,  however  in  recent  years  Portugal  have  lost  market  share  in  these  fields.  This  situation  can  be  related  to  the  level  of  productive  efficiency  of  vineyards.  Therefore,  this  study  aims  to  analyse  the  productive  efficiency  of  wine-growing  farms  and  the  determinants  that  make  farms  more  efficient.  The  specific  hypothesis  to  be  tested  is  if  structural  factors  of  the  wine  grape  farms  are  determinant  of  its  productive  efficiency.  To  achieve  this  purpose,  we  use  a  database  collected  by  face-to-face  surveys  from  a  sample  of  154  wine-growing  farms  with  specific  input-output  information  from  2017.  These  farms  are  locating  in  the  three  regions  of  the  North  of  Portugal  (Minho,  Douro  and  Trás-os-Montes),  which  represents  more  than  40%  of  the  Portuguese  vineyard  area.  To  analyse  the  productive  efficiency  of  the  farms,  we  use  the  Stochastic  Frontier  Analysis  (SFA).  The  results  show  that  the  efficiency  level  in  the  wine-growing  farms  from  the  North  of  Portugal  is  around  68/67%,  but  with  significant  differences  at  regional  level.  Many  of  these  discrepancies  may  be  due  to  structural  factors,  such  as  the  type  of  wine  grapes  and  the  specific  characteristics  of  the  region.  In  conclusion,  farms  must  adjust  produc-tion management to the existing structural characteristics.
