While nearly all cocktails are vegetarian by default, a small number of savory drinks use animal-derived ingredients — most often Worcestershire sauce, which contains anchovies, in a Bloody Mary or Michelada. These vegetarian recipes flag those exceptions. Note that egg white (used for foam in sours), dairy, and honey are all vegetarian, so sours, flips, and creamy drinks are fine.
