According to NPR, the hearings on the beer registration list are going to be about whose responsibility it is to make sure the beers are registered - brewers, distributors, or the bars. The story didn't seem to indicate that they would really be talking about whether or not the whole concept of the registration list is outdated.
Other topics of discussion may be over whether or not to make the PLCB enforcement officers full fledged state police officers so that they can focus on bars where stuff like drug deals happen. According to the guy they talked to the PLCB enforcement officers can't do that right now and if they were in a bar and saw a drug deal take place, they would have to call the police.
