Not long ago I was in New Zealand, and got a chance to visit a number of winemakers in the Martinborough region. Martinborough has a simple problem—it sounds a lot like Marlborough, the much larger and more well-known region on the South Island that provides the template for New Zealand Sauvignon Blanc. Consequently people get them confused.
So, a quick Martinborough primer. It's on the North Island, though it's the southernmost wine region on that island. Various wines are produced there, but the region's strength is Pinot Noir; along with Central Otago, it's one of the best Pinot zones in the country. And it's tiny, less than three percent of New Zealand's total wine growing area.
