Rum, brandy, and bourbon are the classic choices for spiking eggnog, with rum (especially dark or spiced) being the most traditional, and brandy or bourbon adding a richer, boozier kick. Non-alcoholic eggnog simply skips the spirits and is just as common.

Quick Scoop

  • Most traditional: Dark or spiced rum
  • Other classics:
    • Brandy or cognac for a smooth, slightly fruity warmth
    • Bourbon (or other whiskey) for a strong, rich, dessert-like punch
  • Modern twists:
    • Mix rum and brandy together for depth
    • Use flavored liqueurs (like amaretto-style or vanilla liqueurs) in small amounts for extra sweetness and aroma
  • How much to add (rough guide):
    • About 1 ounce of liquor per 4 ounces of eggnog for a single serving, adjusting stronger or weaker to taste
    • For a big batch, many home recipes use roughly ½–1 cup of spirits per quart of eggnog, tasting as they go

Mini Section: Picking Your Spirit Vibe

  • Cozy and classic holiday feel: Go with dark or spiced rum for that warm, festive flavor that blends right into the nutmeg and cinnamon.
  • Elegant, old-school nog: Choose brandy or cognac for a smoother, slightly fruity, traditional style.
  • Bold and boozy: Use bourbon or whiskey when you want more bite and a stronger alcohol presence.

Think of eggnog as a dessert in a glass: the thicker and sweeter it is, the better it pairs with brown, aged spirits that bring warmth, spice, and a little edge.

TL;DR: If you are unsure what kind of alcohol goes in eggnog, dark or spiced rum is the safest traditional bet, with brandy or bourbon as excellent alternatives depending on whether you want smooth or strong.
