Peychaud's Aromatic bitters are famously a required ingredient for the classic  Sazerac cocktail. Also used as a standard aromatic bitters in many other cocktails, these were originally made by Antoine Amedie Peychaud, an apothecary in New Orleans. Their distinct flavour and bright red hue make them a perfect float on a frothy sour or to liven up everything from simple Rye and Gingers to complex Negronis.
