What are some alternative regions producing high-quality Cabernet Sauvignon wines outside of Bordeaux and Napa Valley?

Even though Bordeaux and Napa Valley are the emblematic regions for Cabernet Sauvignon production, several other areas are coming out with top quality wines. The Maipo Valley in Chile has a Mediterranean climate and soils that are well-drained, features that enable the production of balanced and structured Cabernet Sauvignon wines. Stellenbosch in South Africa has a variety of soils and microclimates and produces Cabernet Sauvignon wines that are distinctive and capable of aging. Columbia Valley in Washington State features warm days and cool nights, perfect for the ripening of red Cabernet Sauvignon, and the wine produced from here will have high acidity and exhibit freshness.
