THE Vintage 2010 benchmarking survey gives a bleak outlook on profitability in the wine industry, but Gisborne Wines chairman John Clarke says the industry is working to even supply and demand to improve it. Announced by Deloitte and New Zealand Winegrowers, Vintage 2010 is the fifth annual financial benchmarking survey for the industry that tracks the results of 35 survey respondents. The results show an increase in bulk wine sales at reduced margins, resulting in declining profits across the board.
