Catawba is a red American grape variety used for wine as well as juice, jams and jellies. The grape can have a pronounced musky or "foxy" flavor. Grown predominantly on the East Coast of the United States, this purplish-red grape is a likely cross of the native American Vitis labrusca and the Vitis vinifera cultivar Semillon. Its exact origins are unclear but it seems to have originated somewhere on the East coast from the Carolinas to Maryland. Catawba played an important role in the early history of American wine. During the early to mid-19th century, it was the most widely planted grape variety in the country and was the grape behind Nicholas Longworth's acclaimed Ohio sparkling wines that were distributed as far away as California and Europe. Catawba is a late-ripening variety, ripening often weeks after many other labrusca varieties and, like many vinifera varieties, it can be susceptible to fungal grape diseases such as powdery mildew. Origins The exact origins and parentage of the Catawba grape are unclear. While most sources agree that Major John Adlum was growing the variety at his nursery in Georgetown, Washington, D.C by at least 1823, where he got the cuttings of the vine is unknown with two widowed Maryland women given attribution by different writers. Wine writer Bern Ramey and University of California, Davis viticulture professor Lloyd A. Lider credit Mrs. J. Johnston of Fredericktown, Maryland who wrote to Adlum and said while her late husband always called the grapes "Catawba", she did not know where he got the original vines from. Historian Thomas Pinney describes a similar story with Adlum receiving the cuttings in 1819 from a Mrs. Scholl of Clarksburg, Maryland whose late husband grew the grape. Again, the story goes that Mrs. Scholl told Adlum that while her husband always called the grape "Catawba", she could not recall where the vines came from. It is possible that the source of the Catawba grapes came from the Rose Hill property, in Rockville, Maryland, which was acquired early in the 19th century by Lewis and Eliza Wootton Beall, as part of Eliza's dowry from her father Richard Wootton. It is during their ownership of Rose Hill that grapes were first cultivated on their property. The remnants of these grapes are still evident in the sole surviving grapevine that runs eastward from the side of the barn towards the Rose Hill Mansion. According
