There are no US listings for this rare 2024, but Wine-Searcher lists the average price for other vintages at $49.
Again, here is the British importer:
Le Grand Chemarin is a single vineyard within the Domaine’s holdings. Vinified and aged in barrel, it gives this Sauvignon Blanc wonderful structure and texture which is often hard to achieve. The fruit is brilliantly supported by the creamy mouthfeel.
Again, this almost magically combines the best qualities of a top Sancerre with a top white Burgundy.
And at such a great price!
There are several other Sancerre producers offering this top cru at over $50…but I doubt any can hold a candle to this.
