Laws requiring beer kegs to be registered to better track whether they end up with underage drinkers are gaining in popularity.
Twenty-three states and the District of Columbia have keg- registration laws, according to figures kept by the National Institute on Alcohol Abuse and Alcoholism's Alcohol Policy Information System. That's up from 20 states with such laws in 2003.
Utah bans kegs altogether.
But experts say there has been little research into how effective keg registration is.
Traci Toomey, an associate professor at the University of Minnesota who is one of the few academics to tackle the topic, said research indicates that keg registration's results vary from state to state.
