Both countries have big-league wine industries (Argentina's is the world's fifth-largest), nearly 500 years of vintages, and growing areas with Eden-like climates for farming wine grapes--so warm and dry that grapes easily ripen and pesticides, fungicides, and anti-rot measures are often unnecessary.
