Janemark Winery and Vineyard is located in Southern Prince George’s County, a 45-minute drive south of our nation’s capital. The owners, Jane and Mark, wanted to bring their love of Napa Valley wine country to the east coast and planted Janemark’s first grapevines in 2013. Committed to sustainability, Janemark has successfully transformed fields that once grew tobacco into fields that produce some of the best grapes and wines that Maryland has to offer along with transforming an old tobacco barn dating back to the 1930s into a one of a kind wine tasting experience.
