Memo to Massachusetts wine lovers: There’s more than one way to crush a grape - legally speaking - and the battle to allow winery-to-consumer sales isn’t over yet.

A coalition of wineries, including some boutique wineries in California, is challenging a state law that prohibits consumers from buying directly from 98 percent of the nation’s wineries. The law, passed over Gov. Mitt Romney’s veto in 2005, was actually an end run around a 2005 U.S. Supreme Court decision aimed at ending a variety of state laws that tried to give competitive advantages to their local vineyards.

Instead of playing fair, Massachusetts now allows its wineries (all of them producing less than the 30,000 gallon threshold set by the law) to ship to anyone. But out-of-state wineries producing more than that limit may not ship directly to consumers here. It was, of course, a bald-faced giveaway to local liquor wholesalers.

U.S. District Court Judge Rya Zobel last year found the law had a “discriminatory effect” on interstate commerce and violated the Constitution, but Attorney General Martha Coakley - who you would think might put consumers first - appealed the decision. Monday Ken Starr, representing the out-of-state wineries, told a three-judge appeals court panel, “Massachusetts is a very important market, and this is a very anti-consumer law the Legislature passed.”

He’s right. Our own attorney general should have seen it that way. Now it’s up to the appeals court to make things right.
