Rancid olive oil is most easily identified by its smell and taste: rancid oil smells stale or waxy, and its taste is flat, pungent, or cardboard-like. Fresh extra virgin olive oil, on the other hand, smells fruity and fresh grassy. Rancidity degrades both taste and nutritional value, so it's worth recognizing the differences.<\/p>\n

Oxidized olive oil smells and tastes rancid.<\/h2>\n

Rancid olive oil smells musty, waxy, or like old nuts. The taste is flat or sharp, and the fruity and peppery notes of fresh extra virgin olive oil are completely absent. If the oil has virtually no smell or taste, that also indicates a decline in quality.<\/p>\n

The easiest test: pour a small amount into a glass and smell it. Fresh, high-quality extra virgin olive oil smells like green olives or freshly cut grass. These fresh aromas are gone from rancid oil. The taste test confirms what your sense of smell tells you \u2013 fresh oil should taste fruity and leave a slight peppery burn in your throat.<\/p>\n

How does appearance reveal rancidity?<\/h2>\n

Appearance alone does not indicate quality as reliably as smell and taste, but certain changes can suggest a problem. Color alone does not indicate quality \u2013 the shade of olive oil naturally varies from greenish-gold to yellow depending on the variety and ripeness.<\/p>\n
