It's what we DON'T eat that is significant at Passover; we don't eat any "chametz", or leavened bread products. That includes bread, rolls, pasta, or anything made with wheat flour or grains. The only allowed wheat products are the unleavened bread or "matzoh", or products made from matzoh. For example, matzoh ball soup! Traditional matzoh is made from wheat flour and water, and baked within 15 minutes of adding the water. (Any longer might permit fermentation to begin, which is not allowed during Passover.)
Anything made by yeast or by fermentation of wheat, rye, oats, barley or spelt (a type of Russian winter wheat, also called "groats") is banned. Most Ashkenazic rabbis also ban rice and corn, while many Sephardic authorities permit these as not being proper "grains" mentioned in the Torah.
So beer brewed from barley is chametz, while wine fermented from grapes is allowed during Passover. Whiskey is not allowed, while vodka (made from potatoes) is.
