Argentinian wine laws are not particularly strict or organized. The do have a official bureau, the Instituto Nacionale de Vitivinicultura (INV) whose current power is limited only to regulating the production of grapes and wine exports. Argentinian wine laws do not discuss what grapes are allowed to be grown in which areas or any specific rules for wine making. The only major law of note is that if a varietal is on the label, the wine must consist of at least 80% of that grape.
Argentinian wine makers have mostly been resistant to any additional laws, except in Mendoza. There, the winemakers have begun to codify the various terroir in some of the many subregions, such as Luján de Cuyo, Maipú, San Carlos, San Raphael, and San Martín.
