Aconcagua Valley
Although the Aconcagua wine region is relatively small, it takes its name from the highest mountain peak in South America (Mount Aconcagua), with a reputation for producing some of Chile's finest wines that reach similar heights .
The Aconcagua region itself was originally considered too hostile for grapes to survive. The climate plays an important role in the region; it is characterized by typically warm summers and mild winters with a large difference in diurnal temperatures during the day. The foothills of the valley receive little rain but are irrigated by meltwater flowing down from the towering mountains, which encourages the growth of grapes.
San Antonio Valley
Surrounded by the Santa Lucia mountain range, the San Antonio Valley is a small wine-growing region of Chile, located near the Pacific coast 80 km as the crow flies west of the capital, Santiago. San Antonio Valley viticulture is heavily influenced by the effects of the ocean. This oceanic influence is largely responsible for making viticulture possible here. Cooler conditions during the day and significant drop in temperature at night result in a prolonged growing season and slower ripening period
