Governor Rod Blagojevich just signed a law that will allow Chicago residents to take home unfinished wine from a restaurant.

Restaurants will have to seal the partially consumed bottles of wine securely in tamper-proof bags that would remain sealed during the trip home. If the customer were to be pulled over by a police officer, the sealed bottle of wine would not be considered an illegal open container. The restaurant must also give the patron a dated receipt for the bottle, which is intended to prevent people from carrying the bags in their car and sealing up open bottles of wine during a traffic stop.

"I think a lot of times, when people spend a lot of money for a bottle of wine, they feel compelled to finish it, because they can't take it home," said state Sen. John Cullerton (D-Chicago).

The law won't go into effect until January 1st, so don't go reverse BYO'ing just yet.
