Marlborough is New Zealand's largest wine region, and it's a region where there are some very important growers who sell their grapes to wineries. I visit some of the most important growers in the region with Mike Eaton, who has worked here since the 1980s and now acts as a vineyard consultant. He established the region's first hillside vineyard in 1991. We take a look at some of the more interesting spots in the southern valleys of the Wairau up towards the Wither Hills, and in the Awatere Valley.
