Three years of lees aging, two terroirs (Le Mesnil and Montgueux), one variety (Chardonnay) and zero dosage - '3210'.  This Extra Brut from Gonet is captivatingly delicious and is also an unbelievable value.  The chiseled, precise, mineral-driven and subtly briny profile will have you unconsciously lifting the glass back to your lips over and over again.  It's everything you could ask for from a NV Blanc de Blancs.
