Nectar

Nectar was a type of beverage. This sweet beverage was made from the secretions of a plant's flowers. In the mythology of the ancient Greeks and Romans, nectar was consumed by their deities.

In 2000, Henry Janeway, after finding that he could only serve decaf coffee to Shannon O'Donnell, expressed that it wasn't ...exactly the nectar of the gods.

In 2270, while on planet two of the Taurean system, the Taureans offered nectar to James T. Kirk, Spock, and Leonard McCoy. McCoy felt the nectar was more potent than Saurian brandy. After drinking the nectar, the men went into a deep slumber. 

In 2365, Guinan offered Wesley Crusher nectar from Prometheus while he considered what life would be like away from his mother after she left the Enterprise in 2365.
