A significant proportion of "Made in Italy" olive oil isn't even olive oil.
The only thing that has changed over the last 100 years is that bogus olive oil has gone from being the sole purview of the mafia to being a cash cow for both the mafia and terrorist groups.
More than half the "olive oil" on supermarket shelves, and up to 80% of Italian "olive oil" (if you believe Forbes) is fake. The taste difference between real olive oil and fake olive oil is roughly the same as the difference between real maple syrup and "table syrup." The big difference is that most US consumers know the taste of real maple syrup. They have absolutely no clue what olive oil tastes like because they haven't had it. And if you gave them the real deal, they wouldn't like it. Too phenolic and peppery.
The problem is so bad that anyone can take an open bottle of oil back to the supermarket. And they will quietly and QUICKLY provide a refund to hustle that customer out of the store. Everyone knows this is a big, big problem -- except most US consumers.
It's a safe bet that all that extra virgin, high quality olive oil you've been buying in recent years is not that at all but, rather, poor quality, mixed oils - or maybe not even olive oil at all in a global industry that's rife with corruption.
