The 2021 Chablis Montée de Tonnerre 1er Cru, of which half comprises fruit from the Chapelots climat, has a delightful oyster shell-infused bouquet that blossoms in the glass - citrus peel intermixed with orange zest. The palate is very well-balanced, with a little more weight and concentration than the Butteaux. It is taut and linear, with a lick of salinity on the finish. Excellent.
