The seedlings fruited in the summer of 1992 in a vineyard near Clarksville, Ark. and one was selected for its potential as a wine grape for utilization in the Mid-South of the United States. The original vine was tested as ‘Ark. 2574’. The new cultivar of grapevine is intended for wine production and provides advancements in cold hardiness.
