Nestled between the Andes and the Pacific coast, Aconcagua boasts diverse microclimates. Aconcagua Valley, the heart of the region, enjoys a hot, arid climate, perfect for Cabernet Sauvignon and Carménère. Closer to the coast, Casablanca, San Antonio, and Leyda benefit from the Humboldt Current, ideal for Pinot Noir, Sauvignon Blanc, and Chardonnay.
