Peychaud's Aperitivo. Antoine Amedie Peychaud, the creator of world-famous Peychaud’s bitters, began his career in the 1800s working in an apothecary in the French Quarter of New Orleans making concoctions of his bitters and brandy that he served to peers and patrons. Peychaud eventually became the lead bartender of the Sazerac Coffeehouse where he continued mixing simple cocktails with his bitters to much acclaim. It is this belief in simplicity and quality that serves as the basis for Peychaud’s Aperitivo.
