Regional Spotlight: Martinborough Sauvignon Blanc
Post by Chuck Hayward | April 26th, 2010
The Martinborough region has gained worldwide acclaim for its pinot noir
but few people realize that sauvignon blanc is an important aspect of the area’s wine production. In the last vintage, 47% of the grape production in the Wairarapa region (which includes Martinborough along with the Masterton and Gladstone subregions) was pinot noir while 35% was sauvignon blanc. Yet it is Marlborough that has established itself and gained international recognition for sauvignon.
Sauvignons from Martinborough are quite distinctive and different from the prevailing Marlborough style. The palate profile is typically elegant and restrained with a long, lingering mineral presence on the finish. Flavor-wise, there are the classic lime and lemon citrus elements that are tightly wound about the mineral laden spine. Most examples are tank-fermented with a small portion (usually 10-15%) of barrel fermented juice added to the final blend for complexity. There are some notes of herbs and spices that show the grape’s varietal characteristics, but you rarely see the more pungent, herbaceous aromas that are prevalent in Marlborough.
The minerality that is so clearly evident in Martinborough sauvignons is probably a result of the soils of the region. The so-called “Martinborough Terraces” are considered the geological backbone of the area and are composed of deep layers of alluvial and gravel deposits. These soils are perfect for drainage, but also retard vegetative growth that can increase a grape’s grassy components.
There are relatively few Martinborough sauvignons in the American market despite their ability to offer a distinctively different style to what Marlborough produces. This is partially due to the fact that pinot remains Martinborough’s principal attraction. But it is also a very small region, only 3% of New Zealand’s grapes are planted there yet it only accounts for 1% of the country’s wine production to due consistently low yields. Nevertheless, brands like Ata Rangi, Palliser Estate, Craggy Range and Martinborough Vineyards are worth the search.
