Extra virgin is a tested category, not a generic premium tier
The IOC limits virgin olive oils to oil obtained from olives solely by mechanical or other physical means without treatments beyond washing, decantation, centrifugation and filtration. Extra virgin is the edible virgin category with free acidity no greater than 0.8 grams per 100 grams and the standard's additional chemistry and sensory requirements. Virgin, lampante, refined olive oil, blends and olive-pomace oils follow different definitions. Atlas keeps the exact category, process and evidence attached instead of treating the labels as interchangeable.
