If you can tell first cold press from oil diluted with cottonseed oil by looking you’re God.
In all of history, Olive oil is the most adulterated product next to wine.
Thousands of years, people have been mixing in other stuff and labeling it what it is not.
This is a legitimate function of the government. Like the bureau of weights and measures. A gallon is 128 fluid ounces. 87 octane has a specific meaning, and extra virgin olive oil means a defined set of criteria equivalent to 87 octane means. SAE 10/30 motor oil meets a certain standard. Gold is the same thing here too.
Want some salt to go with your foot? It might taste better when you put it in your mouth like that.
This needed because much of what is marketed as “extra virgin olive oil” is badly diluted or adulterated.
