To facilitate the perception of volatile components such as aromas, the oil must have a temperature of about 28°. It is warmed by holding the glass with one hand and covering it with the other one. Testers place the glass to their nose and inhale deeply, and then taste a few drops, without swallowing them, letting the oil and air contact their taste buds.
