Which is more affordable and good quality? Italian is as expansive, if not even more. Instead Portugal, Greece, Turkey?
Haven’t tasted olive oil from Turkey, but Greek oil is very good, stronger than most Italian or Spanish. But it’s very expensive, and it’s suffering more from droughts and fires.
Portuguese is the same as southern Spain, mostly Picual variety. However it’s not really much cheaper despite what the article claims, unless you go for shit quality.
IMHO go for the cheapest in your area that is extravirgin certified and the variety you like.
