The 2018 Chablis Séchet Vieilles Vignes 1er Cru comes from 0.60ha of 80-year-old vines and spends 18 months on the fine lees. It bides its time in the glass. Discreet at first, it gradually unfurls to reveal quite intense marine aromas of shucked oyster shells and sea cave. This is very well defined but it clearly benefits from decanting. The palate is lively on the entry, presenting a lovely lick of salinity right from the start. Fine energy here, and great focus, with just a touch of spice coming through on the finish and aftertaste. A very fine Séchet from M. Billaud. Recommended.
