St. Louis' giant Anheuser-Busch brewery will make a flavored, caffeinated beer to fight competitors who are attracting young adult drinkers.
Known as Be, the 6.6% alcohol beer will contain 54mg of caffeine, similar to what a 12-oz. can of Mountain Dew contains, ginseng and guarana, a paste derived from a Brazilian fruit, the St. Louis Post-Dispatch reported.
