                                Most popular American light beers, such as Bud Light and Coors Light, have an alcohol by volume (ABV) of approximately 4.2%, which is slightly lower than the 5% found in an average regular beer. This variation is key to understanding how much alcohol is in one light beer and how it affects your consumption.
