The governor of the US state of Massachusetts has blocked a bill that would have expanded out-of-state wine shipments, arguing it was anti-consumer.

Governor Mitt Romney vetoed legislation that would have allowed citizens in Massachusetts to buy wine by mail and take home unfinished bottles from restaurants.

However, the governor said the proposals prohibited shipments by wineries producing more than 30,000 gallons per year, if they have been represented by a liquor wholesaler in the state for the past six months.

"This bill does not give wine lovers the opportunity to purchase the bottlings they want," the governor said. "It creates artificial barriers to protect Massachusetts wholesalers at the expense of a free market."

The state legislature acted after the US Supreme Court ruled earlier this year that Massachusetts and other states could not ban direct wine shipments. Under the old law, only local wineries could ship by mail.
