PRIMA Notes:  The nv Gosset Brut Grande Reserve Brut is a blend of 45% Chardonnay, 45% Pinot Noir and 10% Pinot Meunier, aged for three years on the lees and finished with 7g/liter, tilting it toward the drier end of the spectrum.   The added reserve wine contributes another layer of complexity, making it approachable now without sacrificing age-worthiness; that is, of course, if you have the patience and resolve to leave a few bottles in the cellar.
