I was struggling to find a map which had administrative regions, their corresponding Regiones Viticolas, and nested DOs, so I made one using this old map and the wines of Chile website. Note that the DOs are on the left with the corresponding RV & administrative region on the right. The Atacama and Austral DOs are off the map, but I did list them North to South. Hope it's helpful/do let me know if there are any errors. https://acrobat.adobe.com/id/urn:aaid:sc:US:c0e8b70d-a9cd-48e8-9316-06cc9ac1767d
