ELI5: Why is Olive Oil always labeled with 'Virgin' or 'extra virgin'? What happens if the Olive oil isn't virgin?
gpt
Virgin refers to how many times the olive mash has been processed to extract the oil. Extra virgin olive oil can be skimmed right off the top immediately after the olives are mashed. Lesser qualities of oil are produced by heating the mash and performing other chemical processes to extract the remainder.
