The following article is an interesting example speaking to the importance of oversight, regulation and, in this case specifically, the AOC system of France. Defined by the INAO in 1935 and reformed in 2012, the AOC system is important because it has traditionally been a template for other hierarchical classification systems.* While it serves mentioning that at many points in history individual AOC laws have also served to restrict the inherent potential of certain winemaking regions and individual terroirs, in this case we can cheer a small victory against the less scrupulous in the winemaking world.
*(The AOC system was preceded by and shares structural similarities with the D.O. system of Spain sanctioned in 1932; regulation of Rioja itself preceded both in 1926.)
