With spirits undampened by the cool drizzle, the Smiths of Meredyth held a festival on May 22 to celebrate the 10th anniversary of their winery. A large crowd of wine lovers from Virginia, Maryland and the District of Columbia joined them in the vineyards near Middleburg. As the pipes of the Washington Scottish Pipe Band skirled out of the mist, the public tasted Meredyth's new releases and bought bottles of wine to down with their picnics.

Surrounded by 50 acres of budding vines, the Smiths and their supporters were proving that the confidence of earlier enthusiasts, Thomas Jefferson and Philip Mazzei, was not misplaced. Wine does have a home in the mid-Atlantic states of America.

Today Meredyth is just one of many commercial wineries within a day's outing of Washington. Whether you're a serious collector, an occasional drinker or just, like most of us, someone who enjoys a day in the country, a visit to a local winery offers something for everyone. Not all wineries offer tastings and tours on a regular basis, so call ahead if you're planning a visit.

The number of local wineries is growing steadily. Of those in Virginia and Maryland, the list below is as complete as possible. We've also included two wineries in Pennsylvania whose wines are available in Washington area stores.
