Low-alcohol beer (also called light beer, small beer, small ale, or near-beer) is beer with low alcohol content or no alcohol, which aim to reproduce the taste of beer without the inebriating effects of standard alcoholic brews. Most low-alcohol beers are lagers, but there are some low-alcohol ales.
In the United States, beverages containing less than 0.5% alcohol by volume (ABV) were legally called non-alcoholic, according to the now-defunct Volstead Act. Because of its very low alcohol content, non-alcoholic beer may be legally sold to minors in many American states.
