The wine growing regions of Argentina were originally planted surrounding monasteries, to ensure adequate wine available for use during the celebration of mass. With the immigration of European settlers in the 19th century, more vineyards were planted and new grape cultivation techniques were introduced. By the end of the 19th century, wine production became one of the largest industries within Argentina.
The majority of the country’s vineyards are found in the foothills of the Andes mountain range, where it is common to experience a 50 degree temperature shift from day to night during prime growing season. This promotes just enough stress on the vines to produce rich, complex fruit.
The ecosystem of Argentina produces such favorable conditions for growing wine grapes that the government as enacted strict rules regulating the production of wine. For instance, it is illegal to add sugar to wine.
