manapoli..In the town of Baena, about 60 kms SE of Cordoba we found a store that sells only olive oil-it appeared to be a cooperative of a number of producers. It sold different size bottles plus large cans, various brands. The store is located on the right side of N432,when driving towards Cordoba, on the north side of town, and just before you leave the town. They had 3 each 1/2 litre bottles in an attractive tough cardboard container. To ship back to US we just placed them in our carry-on. So if you want to tour the countryside...
Based on advertisement in hotel magazine there is a specialist store in Cordoba that carries olives, olive oil, etc. Alas we did not make it there due to overstock of olive oil, and understock of available time.
