Local Wine will hold its fifth annual conference April 13, 2013 in Baltimore, focusing on Maryland wine. The state’s industry is one of the fastest growing in the country, and its 61 wineries are almost 50 percent more than in 2010.

The state’s four growing regions allow it to produce a variety of wines, including the classic European varietals but also some that are distinctly New World in style. The Maryland Winery Association is the conference’s primary sponsor.

“We’re growing a world of wine styles and varieties throughout Maryland, and we’re excited to share them through Drink Local Wine,” says Kevin Atticks, the Maryland Wine Association’s executive director.

DLW 2013 will include a Maryland Twitter Taste-off, featuring two dozen of the state’s best wineries, on April 13, plus three seminars featuring some of the top names in Maryland and regional wine.

Maryland’s modern wine history dates to the 1970s, but grapes have been planted in the area since the 17th century. Most of the state’s wineries are in the Piedmont Plateau in central Maryland, but grapes also thrive in the Eastern Shore, Southern Plain, and Western Mountains.

DLW 2013 follows the success of the​ first four conferences — in Dallas featuring Texas wine in 2009, in Loudoun County featuring Virginia wine in 2010, in St. Louis featuring Missouri wine in 2011, and in Denver featuring Colorado wine in 2012. DLW also holds an annual Regional Wine Week, in which wine bloggers, writers and columnists from the U.S. and Canada write about their favorite regional wines, ranging from Ontario to New York to Florida to Texas to Colorado.

Drink Local Wine goal is to spotlight wine made in the 47 states and Canada that aren’t California, Washington, and Oregon. It’s the brainchild of Washington Post wine columnist Dave McIntyre and wine blogger Jeff Siegel, the Wine Curmudgeon.
