The chain was set up when Portsmouth-based Wickham Vineyard bought 14 former Threshers and Wine Rack off-licences following the collapse of First Quench in 2009.
But it went into liquidation on December 30 and Kevin Weir of insolvency firm Benedict Mackenzie has been appointed administrator.
The parent company has also gone into administration, despite the vineyard producing wines served to the Queen during her Jubilee celebrations just seven months ago, leading to a further 24 potential job losses.
The 20-acre vineyard was set up in 1984 and produced 80,000 bottles per year.
Three of its wines were served to the Queen and Prince Philip during a lunch on the day the day Her Majesty celebrated her Diamond Jubilee last summer.
Its demise was blamed on bad weather leading to a poor 2012 harvest. The wet summer also saw Sussex producer Nyetimber scrap its entire 2012 harvest.
