Fine post by Michel Smith on Les 5 du Vin extolling the virtues of Muscadet Haute Expression. This is Muscadet from low yields, specific terroirs which spends a minimum of 48 months sur lie. However, due to the appellation's rules sur lie cannot be mentioned on the labels for these wines as the rules say that all sur lies have to be bottled by 30th November following the vintage. Crazy I know but that is the legislation.
