The Norton grape is the oldest cultivated American grape, first produced in 1820 by Dr. D.N. Norton of Richmond, Virginia. During the 19th century, Norton wines were highly valued in both the US and Europe. Today, farming of the Norton grape is concentrated in Missouri, where it is the official state grape. The Norton is highly adaptable to local growing conditions, as it is durable, hearty and immune to nearly all diseases. Vintners value this grape for its ability to produce high-quality, dry table wine.
