Château Mouton Rothschild, established in 1853 by Baron Nathaniel de Rothschild, is renowned for its prestigious First Growth status, officially attained in 1973 after Baron Philippe de Rothschild's efforts. The estate pioneered bottling its own wine in the 1920s. The wines are primarily driven by Cabernet Sauvignon, which provides rich tannins, depth, and excellent aging potential, with Merlot adding roundness and exceptional length.
