Munamuna believe that anything worth having deserves protection. Were McCorkindale to reveal the secret location of his vineyards, the ensuing rush to acquire any limited quantities of fruit would force prices higher and put the exquisite wines of Munamuna out of reach for many. High security fencing in the heart of Marlborough, around the region's most splendid vineyards has spurred rumours for years, but rumours are rarely true. One unscrupulous operator who knew about the sites and tried to exploit the location was last seen on a small fishing boat talking on a satellite phone in one of the local inlets. What Munamuna can safely tell you is that their Sauvignon Blanc is from the finest vineyards in Marlborough.
