Light beer is a beer, usually a pale lager, that is reduced in alcohol content or in calories compared to regular beers. Light beers may be chosen by beer drinkers who wish to manage their alcohol consumption or their calorie intake; however, they are sometimes criticised for being less flavourful than full-strength beers, or for tasting or actually being watered down.
