Which of these grapes accounts for nearly half of all black varieties planted in Chile?

Cabernet Sauvignon is the grape that accounts for nearly half of all black varieties planted in Chile, making it a dominant force in the country's wine production. This variety thrives in the diverse climates and soils of Chile, particularly in regions such as the Central Valley, Colchagua Valley, and Maipo Valley. The grape's adaptability to various terroirs allows for a range of expressions, from lush fruitiness in warmer areas to more structured and complex profiles in cooler regions.

In addition, Cabernet Sauvignon's popularity in Chile can be attributed to its historical significance and commercial success, as it was one of the first internationally recognized varieties cultivated in the country. The success of Chilean Cabernet Sauvignon has helped establish the country as a prominent wine producer on the global stage, known for its quality and competitive pricing. This has further encouraged vineyards to plant and expand their Cabernet Sauvignon acreage, solidifying its status as the leading black variety in Chile.
