Without a doubt the wine industry is the driving force behind Marlborough's economy and this cache is the forty-seventh in a series by Kiwimykl (and others) to highlight the industry.
Wine Marlborough list 168 wineries on their website and at the time of listing this is the latest in the series.
To buck the trend, again, this is not (yet) at a named Winery/Vineyard, but at the Western most vineyard I know of in Marlborough, more than half way up the Wairau Valley.
A simple park and grab near the river side vineyard.
