You start with a liquid containing some kind of sugar, add yeast, and wait.  The yeast digests the sugar, giving off alcohol in the process.

The sugar in beer comes mostly from a grain called barley.  With wine, the sugar usually comes from grapes.

Either way, when the yeast finishes its work, the sugar has been turned into alcohol-which stays-and carbon dioxide, which bubbles to the surface.  Since wine starts out with more sugar than beer does, it ends up with more alcohol. Find out more on this A Moment of Science.
