Stay away from supermarkets' oils, the true gems of olive oils are sold in small stores and specialty stores.
I have already mentioned the fabolous Petrus from San Juan, and while on vacation in Mar del Plata we also found another two good olive oils: Manjares del sol intenso, from Pocito (San Juan) and San Agustín from Mendoza.
We usually bulk Petrus in bulk at Caminos y Sabores fair in July, but we are open to try new brands for a change. What is your favorite Argentinian olive oil?
