The International Olive Council awarded a perfect score to the olive oil taste testers (sensory panel) at the Australian Oils Research Laboratory in Wagga Wagga, Australia.

This is quite a big deal. People who ‘taste’ olive oil for a living must be able to make very subtle distinctions among the flavors and sensations present in olive oil, and this is very difficult to do.

This past July I attended the introduction to olive oil tasting and the master-level sensory evaluation courses at the University of California at Davis. The auditorium full of students, including me, spent days listening to lectures, taking notes, and tasting many olive oils. The lectures were in Italian and were translated by Darrell Corti of Corti Brothers Fine Wine and Gourmet Foods Italian Grocery Store in Sacramento, California.

Until I took these courses, I had no idea how tough it is to correctly evaluate olive oils. The main things that a sensory panel are looking for are defects in the oils. The defects are a very specific list. Here are some of the more common defects and a link to the list from the Olive Oil Times: Fusty, Musty, Muddy Sediment, Winey-Vinegary, Metallic, and Rancid. There are other defects which are less common but problematic none-the-less.

So why is it that defects are what a sensory panel is really looking for? As our Italian teachers told us, if there is a defect then there is no point in continuing a sensory evaluation. The oil can never be designated as a virgin olive oil and must be sent for refining to be used as a lower grade oil know as lampante (lamp oil) or tossed out.

While you are looking at the link above provided by the Olive Oil Times, take note of the positive attributes. Maybe you have noticed some of these when you taste your extra virgin olive oil. If you haven’t, give it a try, and don’t be hard on yourself if you can’t distinguish the flavors because it is very difficult to do. People who taste-test olive oil professionally take continuous courses to stay on track. I was only moderately good at this and will never sit on a sensory panel. One thing I can do, is tell that there is a defect present, I’m just not good at identifying the defect.

Many congratulations to the Wagga Wagga sensory panel on a perfect score. You have Olive Crazy’s deep admiration.
