Campbell Early mutation grape

The Campbell Early mutation grape is a fruit patented by Swiss emigrants Johann Andreas Wiederkehr and family, owners of Wiederkehr Wine Cellars and Vineyard on St. Mary's Mountain near Altus, Arkansas. An initiator of Arkansas wine culture, Wiederkehr has remained a top producer of fine wines for over a century. The Wiederkehr Winery is a US Bonded Winery, No. 8. The original wine cellar carved into the hillside is the site of the present Weinkeller Restaurant.

Wiederkehr began his wine-making in 1880. He chose Altus specifically for the surrounding area's climate and soil, as they resembled the grape growing climates and soils of Europe. Wiederkehr initially made his wines from wild fruits, including persimmons and blackberries, but soon planted a small vineyard and began experimenting with grape varieties. He developed and patented the Campbell Early mutation grape.
