n. lager with reduced alcohol content
Wikipedia
Light beer (invented in 1967 by American biochemist Joseph Owades) is a beer (usually a Pilsner) 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, tasting or actually being watered down.
