The 2017 Chablis Grand Cru Les Clos was reserved and reductive when I tasted it—the least extroverted of all the wines in Piuze's cellar, as is often the case with Les Clos. Notes of lemon oil, crisp peach and iodine mingling with smoky, leesy nuances introduce a full-bodied, deep and promising wine that is less monolithic than the Valmur but no less powerful. It's really too early to get a clear read on this, but its potential, at least, is clear.
