To avoid misleading consumers Rodney Strong Vineyards is replacing the term "Old Vines with "Knotty Vines" on its 1998 Estate Zinfandel and subsequent vintages. Although the wine is still in a large part from old vines (60-plus years old), the blend now also includes fruit from younger vines. By changing the term to "Knotty Vines" it is hoped that consumers will not be mislead into believing the wine is made entirely from vines of antiquity.
