Château Mouton Rothschild is de enige cru die sinds de start van het klassement in 1855 veranderde van rang. In 1973 werd hij immers gepromoveerd van Second Grand Cru Classé naar Premier Grand Cru Classé. Door de etiketten die jaarlijks aangevuld worden met een foto of tekening van een wereldberoemde kunstenaar is deze wijn een waar collectors item. Collecties van verschillende jaargangen bereiken astronomische waarden op wijnveilingen. Zeldzame flessen zijn zeer veel waard.

Wine Advocate Robert Parker: The 2020 Mouton Rothschild is composed of 84% Cabernet Sauvignon, 13% Merlot, 2% Cabernet Franc and 1% Petit Verdot, with an alcohol of 13.1% and a pH of around 3.78. Deep purple-black colored, it starts off with subtle notions of fresh raspberries and blackberries, needing considerable swirling and patience to unlock its intense core of blackcurrant pastilles, rose oil, licorice and cardamom, plus touches of cedar chest, black truffles and crushed rocks. The medium-bodied palate is like a tightly coiled spring, possessing exhilarating tension and very firm, ripe, multi-grained tannins to frame the layer upon layer of black and red fruits intertwined with earthy and mineral accents, finishing very long and very fragrant. It is certainly the most coy, reticent and elegant grand vin of this trio of vintages (2018, 2019 and 2020), bearing Mouton's signature perfume, opulence and stylishness with great grace and sophistication as opposed to devil-may-care flamboyance. It's this gently teasing, achingly beautiful restraint that collectors are not going to want to miss.
