Sitting pretty on the northern tip of New Zealand's south island, Marlborough has become synonymous with New Zealand Sauvignon Blanc. As well it should be – Marlborough is the primary region for those delicious, citrusy, summer-lovin' wines with vibrant acidity and pungent, grassy, grapefruit flavors. Sauvignon Blanc is the main grape here; Chardonnay, Pinot Noir and Riesling are also made.
