500ML IN A CASE
Extra virgin is the highest quality olive oil. It should have no defects and a flavor of fresh olives.
In chemical terms extra virgin olive oil is described as having a free acidity, expressed as oleic acid, of not more than 0.8 grams per 100 grams and a peroxide value of less than 20 milliequivalent O2. It must be produced entirely by mechanical means without the use of any solvents, and under temperatures that will not degrade the oil.
