How to taste Olive Oil
Pour out a soup spoon of oil in a small glass or in a china cup. Warm it in the palm of your hand in order to exalt the smell and free the volatile aromas. Then put a coffee spoon of oil on your tongue; afterwards move your tongue for a few seconds. Then, shutting your teeth and keeping your lips almost close, move your tongue towards your teeth and brief air at the same time, twice or three times: do everything quite quickly. Thus you sprinkle tongue and palate.
Memorize and trough out.. If you want to repeat the tasting, clean your mouth with spring water.
