Based on the analysis of the tables of the Portuguese Institute of Vine and Wine (IVV), Portugal (Figure No. 4) currently lives, in 2015, a situation of stability in wine production. Over the past 10 years, its production has recorded stable values without large fluctuations.
The production of Protected Designation of Origin wines (PDO) registered a fall in the last decade, even if the year 2000 reversed this trend. The wines with Protected Geographical Indication (PGI) certification have been keeping a stable production (Source Table No. 2).
Despite normal fluctuations on the different years for climatic reasons, the trend is for an apparent stabilization (Source Table No. 2).
Over the past four years we have seen a huge increase in the production of wines identified with the year or varieties, from a zero base, or no available data to 27,000 hectolitres (Source Table No. 2). In the same table (Table No. 2) we are able to verify the existence of a small decrease in the production of wines without PDO or PGI denominations that, however slight, may be a factor to consider in the future.
In general the production of wine in Portugal can be characterized by the stability in the volume of hectolitres produced annually and a slight decrease in wines qualified with PDO, which is, in my opinion, a strategic mistake because the focus must be on the PDO and not on the PGI, as has happened in the last decade.
As shown on the graph, there was a huge increase in the production of wines according to the certification standards between 2000 and 2006, followed by a slight decrease (Table No. 2).
Currently, most of the wine production is carried out by non-associative companies, although a large oscillation between the production of wines by the associative and non-associative companies must be registered In percentages, between 2000 and 2004, the associative enterprises (largely cooperatives) were responsible for producing the majority of the volume of Portuguese wines; however, since 2005 that trend reversed, with non-associative companies to register the increased production of national wines. This fact reveals the rigour and strategy on the quality of Portuguese wines and the focus on specialization and training of professionals in the wine sector.
