Eggnog is widely believed to have originated in medieval Britain, evolving from a warm, milky, spiced ale or wine drink called posset that monks and the aristocracy enjoyed as a rich winter treat. Over time, this posset-like drink was enriched with eggs and expensive spirits, then carried to Britain’s American colonies, where abundant dairy and cheaper rum helped turn it into the creamy holiday eggnog known today.

Where Did Eggnog Originate?

Most food historians trace eggnog back to:

  • Medieval Britain, where posset—a hot mixture of milk curdled with ale or wine and spices—was popular from at least the 14th century.
  • Monastic traditions, with medieval monks in Britain drinking richer versions of posset with eggs and figs by the 13th century.

Because milk, eggs, and imported wine or sherry were expensive, this early “eggnog-like” drink became a symbol of wealth and was often used for toasts to health and prosperity among the English aristocracy.

How Posset Turned Into Eggnog

As the drink evolved, several key changes nudged it toward what people now search for as “where did eggnog originate”:

  1. From simple posset to egg-rich custard drinks
    • Posset began as milk plus alcohol and spices, but recipes gradually incorporated beaten eggs, creating a thicker, custard-like texture similar to modern eggnog.
 * By the 17th century, sherry and other fortified wines were common, and these richer, eggier versions were used in formal toasts.
  1. A drink of the elite
    • Because of the cost of dairy and alcohol in Europe, this early form of eggnog remained primarily a luxury beverage of the upper classes.
 * Its association with special occasions helped cement its later role as a Christmas and New Year’s drink.
  1. The name “eggnog” appears later
    • Linguists suggest “nog” may come from “nog,” a strong beer from East Anglia, or from “noggin,” a small wooden mug used for serving alcohol.
 * The combined term “eggnog” shows up in Britain’s American colonies in the 18th century, rather than in medieval England itself.

Eggnog Crosses the Atlantic

When asking “where did eggnog originate” in today’s context, many also think of its American twist:

  • In the 1700s, the drink reached the American colonies, where farms provided plentiful cows and chickens, and Caribbean rum was cheaper and easier to obtain than European wines.
  • Colonists swapped in rum (and later bourbon or other spirits), helping create a distinctly New World style of eggnog that became strongly tied to American holiday traditions.

From there, variations spread:

  • Mexico developed rompope , a close cousin of eggnog made with eggs, milk, sugar, and usually rum or other spirits.
  • Puerto Rico created coquito , a coconut-milk-based relative that blends rum, coconut, and spices for a tropical holiday drink.

Modern Eggnog and Cultural Buzz

Today, “where did eggnog originate” is a seasonal trending topic every December as people debate whether the drink is delicious, nostalgic, or just odd. Modern eggnog is typically:

  • A sweet, liquid-custard mixture of beaten eggs, sugar, and milk or cream, often flavored with nutmeg and sometimes cinnamon.
  • Served with or without alcohol, using rum, brandy, bourbon, or other spirits depending on regional taste and family tradition.

Online forum discussion often centers on:

  • Safety and technique (cooked vs. raw-egg recipes, and how much alcohol is “traditional”).
  • Personal twists like extra spices, different spirits, or plant-based substitutes that still nod to the drink’s rich, medieval-British roots.
