 Rack bright beer generally costs slightly more than ordinary beer, all else being equal, and requires more preparation time and care at the point of serving; in particular, dropping bright requires that the beer be left undisturbed to settle, as jarring or shaking its container will re-suspend the yeast.Any beer which has dropped bright or fined will have a layer of yeast sediment at the bottom of its storage vessel.Finings can be introduced during the production of beer in order to induce it to drop bright more readily.
