Aromas of pear, green apple and citrus oil mingling with hints of fresh bread and oyster shell introduce Dauvissat's 2018 Chablis Grand Cru Les Clos, a full-bodied, layered wine that's ample and elegantly muscular, girdled by bright acids and revealing more overt structure than Les Preuses at this stage. Concluding with a long, chalky finish, even in the demonstrative 2018 vintage, this will merit a bit of patience.
