(MPNNow) - Last week, New York’s southern neighbor Pennsylvania caught the attention of the wine industry when Gov. Tom Wolf signed that state’s most significant liquor reform bill since Prohibition. It puts the state in line with most other states, including New York, by allowing direct wine shipment from producer to consumer.

But the biggest deal in the Keystone State's new law: Wine in grocery stores. Wine bottles could be in the grocery carts of Pennsylvanians as early as August.

The change is making some in New York’s nearly $5 billion wine industry nervous.

On the heels of the news, Carol Doolittle, co-owner of Frontenac Vineyard and Estate Winery overlooking Cayuga Lake, sent out a mass email alerting wine industry colleagues and lawmakers of what is happening just over the state line. Long an outspoken advocate for wine in New York's grocery stores, Doolittle sees this latest development as further limiting New York’s wine market at a time when the state’s growing industry needs to expand.

“Do you understand that this will diminish our PA tourist trade?” she wrote in the email. It’s a trade “we in the FLX depend on coming to our wineries and buying our wine to pay our bills …” she said. Meanwhile, Pennsylvanians will have “more choices and better prices in their hometown” as that state collects more tax revenue, she said.

The debate in New York over wine in grocery stores is nothing new. Lobbying on both sides of the aisle has gone on sporadically for years. In 2010, at the height of the most recent heated exchange, the topic bubbled to the top at the Viticulture 2010 convention and trade show held at Rochester Riverside Convention Center. Then Gov. David Paterson, a proponent of wine in groceries, pushed for the allowance and the millions in revenue it was projected to bring in taxes. Wine in groceries had the backing of powerful lobbying groups such as New York Farm Bureau, Food Industry Alliance and New York Wine Industry Association.

Winery owners remained divided on the issue, as did legislators. When Gov. Andrew Cuomo took the helm in 2011, he did not include it in his budget.
