A post-prohibition Maine law has come back to haunt brewers in 2014. State liquor inspectors have started cracking the whip on restaurants and brewers that display a beer's alcohol content. Yep, it's actually illegal in Mane to show a beer's potency on signs and menus.

The law was enacted in 1937, and is now far from valid, says most. In fact, lawmakers don't even know why it was added to state law. Based on documents from that time, it perhaps was a move to prevent advertising beer based on it's potency.

The law resurfaced a at a bar in Belfast, where a liquor inspector laid down the law a few weeks ago. Ever since, bars and restaurants have been taking black sharpie to their menus.

In today's craft beer boom, listing alcohol content is important information. Some brews go down easy but pack a punch. Restaurants say alcohol info is important for patrons to plan how many beers they can put down.

State Rep. Louis Luchini of Ellsworth has taken the reigns, proposing an emergency bill to remove the language about alcohol content and to clarify the laws original purpose of protecting beer lovers.

The process of moving the bill along to legislators could take months.
