Wort , noun

An infusion of malt which is unfermented, or is in the act of fermentation; the sweet infusion of malt, which ferments and forms beer; hence, any similar liquid in a state of incipient fermentation.

Wort consists essentially of a dilute solution of sugar, which by fermentation produces alcohol and carbon dioxide.
