Situated at the northern tip of New Zealand's South Island, Marlborough is now the country'slargest wine region. Since the 1970's when Montana started investing hugely in the area, vineyardplanting has continued apace and the number of producers is now over a hundred. The unique combination of long, sunny days, cool nights and dry autumns enables the grapes to reach maximum phenolic ripeness while retaining their acidity. Its Sauvignon Blancs, as personified by the crisp, smokily aromatic Cloudy Bay, are now world-famous. Fine Pinot Noir and Chardonnay are also grown.
