Tasting extra virgin olive oil

The aromas of olive oil are a critical part of its flavor. Put
a little bit of extra virgin olive oil into a small glass. Hold it, swirl it, warm it for a minute or two. Then put your nose in the glass and take in the aroma or “nose” of the olive oil. You may notice the smell of fresh-cut grass, cinnamon, tropical fruits or other aromas of ripe or green olive fruit.

Now take a sip. You want to get the impressions of the entire mouth. Suck air through the oil to coax more aromas out of it, and then — this is important — close your mouth and breathe out through your nose. This “retronasal” perception will give you a whole bunch of other flavor notes. Retronasal perception is possible because your mouth connects to your nose in the back. Now swallow some, or all of the olive oil.
Pungency is a peppery sensation, detected in the throat, and a positive characteristic of olive oil. It is a chemical irritation, like the hotness of chilies, and equally appealing once you get used to it. Pungency can be very mild—just the tiniest tingle—or it can be intense enough to make you cough. Olive oil aficionados will sometimes refer to a one, two, or look out, a three-cough oil.
The third positive attribute of olive oil, in addition to fruity and pungent, is bitter. Bitterness, like pungency, is also an acquired taste. As anyone who has ever tasted an olive right off the tree can attest, bitter is a prominent taste in fresh olives. Since olive oil is made from uncured olives, varying degrees of bitterness can be found; oil made from riper fruit will have little to no bitterness, oil made from greener fruit can be distinctly bitter. American taste horizons are broadening; we are exploring bitterness with foods like dark chocolate, bitter salad greens and now, robust olive oils.
The fruity characteristics you may notice in the mouth include nutty, buttery and other ripe flavors, and a fuller spectrum of green fruity notes. The traditional palate cleanser between olive oils, is water, plain or sparkling, and slices of Granny Smith apple.
