Chablis is the largest wine region in Burgundy, but it’s actually closer to parts of Champagne than the Côte d’Or (the backbone of Burgundy). That’s to say, it’s way up north, and the cool climate leads to lean, light-bodied wines that taste tart and acidic like green apple and lemon. Another reason why Chablis benefits from a couple extra years of age is that it’s often grown on chalky soils, and due to the high levels of acidity produced from grapes on these soils, it remains super fresh and delicious at even 15 years of age.
