Relen tea

Relen tea was a Vulcan tea.

Spock considered relen tea to be a personal favorite. When Praetor Gell Kamemor served Spock a type of tea from Glintara I, Spock found it was not unlike relen tea. 

In 2383, Kamemor offered Tomalak relen tea. Tomalak declined, as he disapproved of a Praetor indulging in an offworld beverage of Federation origin. (Star)
