Peychaud's is a brand of cocktail bitters invented in the 18th century by New Orleans apothecary Antoine Amedie Peychaud. Like most bitters, the recipe is a secret. Bright pinkish-red color and clear, it smells of tutti-frutti, licorice and flowers. By cocktail bitter standards, it's only slightly bitter. It's best known as the bitters and essential ingredient in the Sazerac cocktail. Both the cocktail and the bitters are strongly linked to New Orleans. It's quite versatile in drinks, as it's not as heavy as most bitters.
