Traditionally, Vietnamese tea drinking is considered a hobby of the older, more learned members in households and in society in general, although currently it has been becoming more popular in younger demographics as well. Tea drinking would accompany aristocratic activities such as composing poems, tending flowers, or simply appreciating nature.

• Lotus tea (trà sen) is a specialty product of the Vietnamese tea industry. Generally, high-quality green tea leaves are placed within lotus flowers for a day to acquire the scent, then the tea leaves are removed and packaged. A higher grade of lotus tea is made with lotus petals mixed in with high-quality green tea leaves. Green tea style of Vietnam is to roll the leaves gently into crescents, and minimal handling. Vietnamese green teas are typically very potent. They are best brewed for most tastes for under 2 minutes using water temperature of 70 °C (160 °F). Beyond this time the tea will acquire a bitter taste that is nevertheless preferred by many tea lovers, as it reflects the potency of the tea leaves. Some tea lovers will brew 3-4 times from one set of leaves, preferring the narrower flavor range of the later brewings.
