While the late-April frost may have been less damaging in Chablis than it was on the Côte de Beaune, large additional swaths of the greater Chablis region were ravaged by two hailstorms in May. This map shows how extensively the Chablis region suffered from frost and hail this spring (grêle is hail and gel is frost). Note that the Grand Cru slope in the heart of the appellation was virtually untouched.
