How many glasses do one barrel of beer really make? Café owners testify: “Tapping has to be done according to the rules of the art and beer is lost with every glass” | Inland

A difference of 24 or a full tub of beer that, according to the bar bosses, is not sold, but disappears in the pump tank. Where does beer go to waste with a 25 centilitre tapped pint? We went to investigate.
