This vermouth thought of as a wine, expresses with elegance and finesse all the complexity of François' favorite grape variety: Sauvignon Blanc. Léonce Extra Dry Sauvignon Blanc is made from a base of Sauvignon Blanc wine from our Domaines des Fumées Blanches. Fortified with a Sauvignon Blanc eau-de-vie, the wine is then enriched with botanicals via maceration or blending of distillates.
