The Ritchie Vineyard is one of the most famous Chardonnay sites in Sonoma County. The vineyard was planted in the early 1970’s to a Wente clone of Chardonnay on AXR-1 rootstock.  It was later discovered that AXR-1 was not phylloxera resistant and owner Kent Ritchie was told he would need to replant the vineyard. Forty years later the vineyard still produces world class fruit!
