Deemed the world's greatest white wine, Château d'Yquem is located on a small hill and benefits from an exceptional micro-climate and terroir. The vineyard encompasses no fewer than 150 plots of different soil, and is pampered throughout the year, with each individual vine undergoing an average of 50 different treatments per year. The selection process at Château d'Yquem is particularly stringent, with a local saying holding that a single vine makes a single glass of wine. Harvesting involves a minimum of four different passes (seven passes took place in 1997!) in order to ensure the grapes harvested have reached perfect maturity and have been affected by noble rot. Time is taken with every step of the vinification and ageing processes. The wine spends up to 20 months ageing in new barrels.
The estate also produces a dry white called Y d'Yquem from grapes that are free from noble rot. In some years, the entire harvest is de-classified (there was no wine produced in 1910, 1915, 1930, 1951, 1952, 1964, 1972, 1974, 1992 and 2012). Since 2022, the property has held organic certification (AB/ Eurofeuille).

Y de Yquem is not a second wine, but a dry white wine produced by the Château d'Yquem since the vintage of 1959. It benefits from the same care and treatment given to the prestigious grand cru classé, using grapes that have not been affected by noble rot. The end result is a fine, elegant wine that develops aromas of candied citrus fruits, acacia flowers and bergamot. On the palate, it releases incredibly delicate woody and roasted notes.
