A popular effervescent drink, black in color, is called 'awje'. This is frequently, though not accurately, translated as "root beer," probably because of its superficial resemblance to the Federation soft drink, but it is made from, among other things, the marrow (melchoQ) taken from the bones of a teg'bat. It is considered relatively mild, even for a Klingon nonalcoholic drink.

This word is commonly used to refer to any non-potent beverage.

Pun: A&W (a w je)
