Cuyo is the name given to the wine-producing, mountainous area of central-west
Argentina. Historically it comprised the provinces of
San Juan,
San Luis and
Mendoza and was influenced by
Chile. The modern term
New Cuyo indicates both Cuyo proper and the province of
La Rioja. New Cuyo is a political and economic
macroregion, but culturally La Rioja is part of the
North-West rather than of Cuyo.
