(NBCPhiladelphia) - The New Jersey Wine industry is getting bigger and bigger. New Jersey Monthly just dedicated a whole issue to it. "New Jersey is the seventh largest wine grower in the country, so it is a big deal," says Ken Schlager with New Jersey Monthly.But with growth comes growing pains. A new law set to go into effect in May will allow New Jersey wineries to ship directly to customers in most of the country and out-of-state wineries will be able to ship direct to New Jersey houses as well. "If it's not broke, why fix it?" asks liquor store owner Michael Maro. He and other liquor store owners don't like the law. Maro wants people to buy their wine from him. He worries he could go the way of Blockbusters and Borders. Maro thinks local wineries should understand -- even with direct shipping -- they will sell far more wine on local store shelves. Wineries that have sided with him are now getting better shelf space at his store. The wineries that pushed hard for direct shipping, well, you're gonna have to look harder to find their products at Canal's Discount Liquors.
