The Napa Valley Reserve is a private wine club founded by William Harlan, owner of Harlan Estate Winery. It is located on 80 acres in St. Helena and its members pay a significant entry fee of more than $100,000 and help with certain winemaking activities, such as harvesting grapes. Members also pay for allotments of wine, which are not available for sale from the club. These are wines made for international wine collectors.
