Chile's walnut-producing regions range from Valparaísoin the North, to Maule in the South. The production regions are as follows:
Metropolitana, 16,430 ha, 38% of the total area,
O'Higgins, 7,786 ha, 18% of the total area,
Maule, 7,008 ha, 16% of the total area,
Valparaíso, 7,003 ha, 16% of the total area,
Coquimbo, 2,145 ha, 5% of the total area,
Ñuble, 1,498 ha, 3% of the total area,
Biobío, 1,426 ha, 3% of the total area,
Others, 438 ha, 1% of the total area,
The harvest season starts mid-April and coincides with the In-shell export season. For shelled walnuts the export season starts slightly later after nuts are processed.
Export Season (High Season):
In-shell (raw): Mid-April – August
Shelled (kernels): May - August
The key advantage of Chilean Walnuts is that their seasonality is the reverse of that of California and other Northern Hemisphere producers.
