L’Essence de Courvoisier is a high end cognac from the House of Courvoisier. The crystal decanter actually looks like a teardrop, and fills 70 cl of a fine blend. Over 100 rare eaux de vie, some date back to the beginning of the 20th century are united in this Cognac. The crystal bottle comes from Baccarat. This decanter has a very special history: It is formed in the shape of a ring, actually it is a reference to Napoléon.
