The 1999 Cote Rotie Seigneur de Maugiron is brilliant. It boasts a black/purple color as well as sumptuous aromas of espresso, graphite, violets, and blackberry/cassis fruit. This is underlined by abundant power, good acidity for definition as well as freshness, and a superb, pure finish. This exceptional Cote Rotie requires 4-5 years of cellaring. Anticipated maturity: 2005-2018. Beginning with the 1997 vintage, this firm has made remarkable progress with their Cote Rotie program. The cuvaison lasts twenty days, and Jacques Granges believes in several pigeages (punching down) a day, with pump overs as well.
