1. Cocktail Punk's Cherry Bitters
    Absolutely a must-have for manhattans, old fashioneds, and any whiskey cocktail!
  2. Fee Brothers Celery Bitters
    A delicate but delicious addition to most any cocktail. However, I stopped buying Fee Bros when I realized they put additives into most of their bitters.
  3. Dr Adam Elmegirab's Boker's Bitters
    In manhattans it adds a chocolatey flavor; in martinis it turns the cocktail smooth and distinctive.
  4. Dutch's Spirits Prohibiters
    Puns! Also, it adds a certain je ne sais quoi to martinis.
  5. Underberg
    A potable digestif bitter that's survival medicine for the holidays.
