1945 was quite an outstanding year for First Growth Bordeaux. However, Mouton, which still held Second Growth status at that time, was undoubtedly the hot ticket of that year. Not only was its demand in the market more than all the four major estates of that time, the owner of the estate, Phillipe, also began considering the promotion of Mouton to First Growth status.

There was cause for celebration during that particular year. This wine was vinified soon after the end of World War II, and, for the first time, artist drawings were placed onto the wine label. The significance of victory that year and its symbolism with the letter, "V," add to Mouton's collection value alongside the rare and exquisite flavors it imbues. A hot harvest year birthed a rich, full-bodied wine that achieved the standard alcohol level of 15%. However, only a few were produced that year. The wine critic, Robert Parker, gave Mouton a full score of 100-points, hailing it as one of the immortal wines of the century and estimating that it could be stored for at least another 40 years.
