Chill beer like champagne; surround with ice cubes and turn gently a few times. Don’t serve it too cold, for it goes flat. Don’t shake bottle or can before opening. Open gently to prevent gushing. Once opened, serve promptly! Don’t tilt glass to allow beer to slide slowly down side! Instead pour beer into center of glass, holding bottle or can at a high angle until a head comes up. Then pour beer more slowly. Most people prefer a firm head, about 1" deep.
