Casablanca Valley sits 60 miles (100km) north-west of the country's capital, Santiago. Viticulture began in the region in the mid-1980s, making it one of Chile’s youngest grape-growing regions. However, Casablanca Valley is fast becoming renowned as Chile's top region for white wines, producing excellent Sauvignon Blanc, Chardonnay, and Riesling. Influenced by the sea and situated close to a coastal mountain range, the Casablanca Valley region has a very unique climate, which produces a slow maturing of its grapes. Being only 20 miles (30km) from the Pacific Ocean, Casablanca Valley picks up the cooling effects of the Humboldt Current, which flows up the west coast of Chile from the Antarctic. The terroir varies extensively, from sandy loam to clay and in places, gravel.
