Comoz Vermouth de Chambéry Blanc is produced by Maison Dolin from the classic 1881 recipe created by Jean-Pierre Comoz, who left Dolin in 1856 to found his own eponymous house. Comoz is credited with creating the first òpale-style’ vermouth, what is now categorized as òblanc’. The only vermouth blanc sold in Cuba, it was the defining element of the famous El Presidente cocktail. Comoz remained in family hands until 1981, when the house ceased production and closed.
