While all Sauternes share the same botrytised harvest process, Château d'Yquem stands apart through several fundamental elements. First, its yields are the lowest in the appellation: on average, only one glass of wine is produced per vine, compared to a full bottle elsewhere. Furthermore, in years deemed insufficient, the château does not hesitate to produce no grand vin at all, as was the case in 1972 and 1974 — an exceptionally rare decision that reflects an absolute uncompromising stance on quality. Finally, ageing in new oak barrels for three and a half years gives Yquem a structure and depth that its neighbours, excellent as they are, only rarely achieve.
