The 2017 Chablis 1er Cru Montée de Tonnerre is showing well, opening in the glass with aromas of crisp green apple, citrus oil, white flowers, pastry cream and smoke. On the palate, it's medium to full-bodied, broad-shouldered and powerful, with a deep core of ripe fruit, bright acids and saline finish. Reserved without being austere, it will reward some bottle age.
