FOAMY BAR DRINKS can refer to a variety of alcoholic beverages, such as BEERS, ciders, and ales. BEERS are the most common type of foamy bar drink, and they come in a wide range of styles, from light lagers to dark stouts. Ciders are made from fermented apples, while ales are brewed with hops and malted barley. All of these drinks have a foamy head when poured, which is created by carbon dioxide released during fermentation.
