Lots of people are going to respond to this with comments about how most olive oil in the US is fake.

This is based on an old study [1] and is no longer the case.

It's now FUD perpetuated by DTC brands as part of their marketing. [2]

Your [1] is an olive oil industry marketing site that provides no evidence.

Better would be a similar study to the original UCDavis study, to check if quality has improved.
