What are some emerging regions producing high-quality Sauvignon Blanc wines?

Even though the traditional Sauvignon Blanc regions are known to include France, New Zealand, and California, there are a few emerging regions that are being recognized for making outstanding examples of the Sauvignon Blanc varietal. The cool climate and the influence of the Pacific Ocean in the Casablanca Valley of Chile produce many Sauvignon Blanc wines with very lively fruit flavors and crisp acidity. In the same manner, the Walker Bay area in South Africa is now very well-known for its elegant and also expressive Sauvignon Blanc that presents a unique harmony between the fruit and the minerality.
