Delicious, sweet, and special, nectar is the best juice you can imagine. When the ancient Greeks visualized the gods having a party on their Olympian lawns, they saw nectar in their cups.
Nectar was originally used to describe the drinks of the gods, but regular old humans need the good stuff too. Serious wine lovers would describe their drink as nectar, while the serious raw food eater might save the term for a ginger-beet-cayenne juice. If you ask the hummingbird, she would give you a very tiny straw and direct you to the nectaries of a flower.
