HARTFORD — Governor Dannel P. Malloy is not giving up on his long-running attempt to overhaul Connecticut’s liquor laws.

Despite opposition during previous legislative sessions, the Democrat this year has again proposed a bill that would eliminate so-called minimum bottle pricing. Current state law generally prohibits retailers, such as package stores, from selling alcoholic liquor other than beer below a minimum price.

Malloy contends that is unfair to the consumer and ultimately hurts Connecticut tax revenue collections.

‘‘When in doubt, stand up for the consumer,’’ Malloy said in an interview, estimating prices in Connecticut are $4 to $12 more per bottle than in other states. ‘‘And the idea that Connecticut consumers are paying so much more money for wine and spirits than are paid by the surrounding states is quite indefensible.’’

As in past years, the state package store owners association is opposing the move. The group argues that the price difference between states, which it estimates is $2 or $3 per bottle, has more to do with taxes than the minimum pricing law, and warns that Malloy’s latest bill could lead to a 10 percent drop in revenues and force 600 of the state’s approximate 1,150 liquor stores out of business, resulting in an estimated 2,100 job losses.
