It depends on what you are trying to do with it. As long as the yeast has something to eat (ie, sugars), it will be producing ethanol (alcohol) and carbon dioxide (which makes bread rise). When people make things like beer, they use fermenters so bacteria doesn't get into it, and so they can keep the alcohol in, as well as the co2. When you make bread, the co2 produced by the yeast will make the bread rise, and then the ethanol gets cooked off when you bake it.
