Begin by pouring a tablespoon of olive oil into a small glass. Cup the bottom of the glass in your hand to warm the oil; cover the top with your other hand and swirl gently to release the aromas.
Bring the glass to your nose and smell the oil. Take a note of the aromas.
Next, take a slurp. As you do so, touch your tongue to the back of your top teeth and inhale. This spreads the oil in your mouth and helps release the flavors of the olive oil.
Finally, swallow the oil and take note of the flavors you experience.
A mild stinging in your throat is a good thing and demonstrates that the oil is rich in antioxidants called polyphenols.
Bitterness at the back of your tongue is also a good thing and is a sign that what you are tasting is indeed an extra virgin olive oil.
