Within a short time he transformed the traditional vineyard into one of the most important châteaux in the world. Doing many things differently from his contemporaries, he invested a lot of heart and money into the modernization and expansion of the winery. He was the first to bottle his wines, in order to guarantee the uniqueness of their origin. It was him who coined the term "mis en bouteille au château" - still valid today as a quality criterion. One of his greatest achievements, however, is the creation of Mouton Cadet. Referring to the expression "Cadet" ( "the youngest") - Baron Philippe being the youngest of three siblings - he conceived it originally as a second wine. However, the Cuvée enjoyed such great popularity that their quantities could no longer satisfy the increased demand. So the Baron bought selected grapes and created the most successful premium wine of France ever. The selected qualities of Réserve Mouton Cadet line are more than elegant brand wines: They are ambassadors for the most famous appellations of the Bordeau and reflect the unique character of each terroir perfectly. Each réserve wine is composed carefully by Baron Philippe de Rothschild winemakers and tells in a very individual way about its origin. The réserves are produced in limited quantities and are linking to the top wines of the house.
