A Grower’s Map of Argentina

Argentina is South America’s biggest olive producer, and almost all of it grows in the dry, sun-blasted west under the Andes. If you want to understand Argentine oil and olives, start with the map: a handful of high-altitude provinces doing the heavy lifting. Here’s the lay of the land.

The western heartland

The action is concentrated in the arid northwest and west: La Rioja, Catamarca, San Juan and Mendoza, with Buenos Aires province on the coast a smaller player. These are hot, dry, high-altitude lands where olives thrive with irrigation from Andean meltwater. La Rioja and Catamarca lean toward table olives — this is where the giant Arauco, Argentina’s own variety, is at home — while the cooler, wine-country reaches of Mendoza and San Juan produce a good share of the oil. Intense sun, cold nights and very low humidity give clean, healthy fruit with little disease pressure.

Arauco and the imports

Argentina’s signature is the Arauco, a large green olive descended from Spanish stock that does double duty for table and oil. Alongside it, growers plant the international cast: Arbequina, Frantoio, Picual, Manzanilla and others, much of it on modern irrigated estates aimed at export. The harvest falls in the southern autumn, March through May, so Argentine oil reaches northern shelves fresh mid-year. The country sends much of its crop abroad, both as bottled oil and as bulk table olives, making it a quiet but serious presence in the global trade.
