It's a two-step process:

1) Sugar (sucrose) is broken down into two molecules of glucose.

C12H22O11 + H2O + invertase----> 2C6H12O6

2) The two glucose molecules are broken down into ethanol and carbon dioxide.

2C6H12O6 + Zymase ----> 4C2H5OH + 4CO2

You can find out more by going to the Ethanol fermentation article on Wikipedia.
