Marlborough can lay claim to starting the modern New Zealand wine industry. Here in the late 1970s, Marlborough produced Sauvignon Blanc, among other varieties, which led to confidence that New Zealand could produce interesting wine.
Today, the Marlborough wine region represents 62% of total vineyard area in the country. The king varietal here is Sauvignon Blanc, closely followed by Pinot Noir and Chardonnay.
The strong contrast between hot sunny days and cool nights help vintners extend the ripening period of their vines like nowhere else, resulting in unique expressions of their grapes. For example, Sauvignon Blanc from Marlborough offer unique aromas and flavors, which earns them much praise from wine lovers around the world.
The majority of Marlborough’s extensive vineyard plantings are around Renwick, Blenheim, and Cloudy Bay in the Wairau valley. Further south in the Awatere valley are plantings near Seddon. These are for the most part on old terraces of the Wairau and Awatere rivers.
The area is widely considered by many critics to produce the world’s best Sauvignon Blanc.
In the 1990s, Sauvignon Blanc wines from the maritime climatic regions of New Zealand, particularly the South Island, became popular on the wine market. In the Marlborough region, sandy soils over slate shingles have become the most desirable locations for plantings due to the good drainage of the soil and poor fertility that encourages the vine to concentrate its flavors in lower yields. In the flood plain of the Wairau River Valley, the soil runs in east-west bands across the area. This can create a wide diversity of flavours for vineyards that are planted north-south with the heavier soils producing more herbaceous wines from grapes that ripen late and vines planted in stonier soils ripening earlier and imparting more lush and tropical flavors. It is this difference in soils, and the types of harvest time decisions that wine producers must make, that add a unique element to New Zealand Sauvignon Blanc.
