Mouton Cadet, the most successful Bordeaux brand, began life in 1927, a poor vintage in which Baron Philippe de rothschild created what was effectively a second wine called Carruades de Mouton for Ch mouton rothschild. Penning-Rowsell notes that it was not a success, and its successor in 1930 was named Mouton-Cadet, since Philippe was the cadet, the youngest, of the family. Eventually, as Mouton Cadet, it developed a prosperous life of its own, and demand was so great that the flexibility of the bordeaux aoc appellation was needed.
