Franck Bonville "Unisson", Avize Grand Cru, Blanc de Blancs, Brut NV 750ml

As with their flagship Blanc de Blancs, Bonville’s Grand Cru cuvée “Unisson” (“unison”) can vary from year to year in vineyard sources, reserve wines, and dosage levels, but their aim here is a more complex and mineral-dominated character than the flagship—a profile enhanced by spending more time on the lees before disgorgement. This release comes entirely from holdings in the grand cru Avize, from roughly equal proportions of the 2017 and 2016 harvests, and it was disgorged after nearly five years on the lees with a dosage of 6.7 grams per liter. A salty, authoritative nose introduces a palate of greater depth than that of the flagship, with a clean and stony finish of impressive length.
