The aroma of the tea is of a very volatile nature, and after one infusion, when the fragrance comes drifting up, you can become partly intoxicated without having a sip. But the aroma will disperse quickly, so you will want to let your mouth and oral cavity experience the tea. Take a mouthful and hold it in your mouth without moving it, letting the aroma ascend. Move it vigorously to your cheeks, so that the aroma can move to your nasal cavity. This style of drinking is very good for experiencing the aroma of the tea.
Some teas smell wonderful as dry leaf but develop little fragrance when infused and sipped.
