Eggnog originated in medieval Britain as a variation of "posset," a hot, milky drink made with ale, eggs, and figs consumed by monks as early as the 13th century. The name "eggnog" first appeared in the British North American colonies around 1775, where it evolved using abundant local milk, eggs, and cheap Caribbean rum due to taxes on brandy and wine.

Origins Debate

Historians trace eggnog's roots to 14th-century England, but some sources note even earlier mentions in colonial America, like a 1759 description in "History of New Sweden" by Israel Acrelius. While Britain claims invention for aristocrats, the drink exploded in popularity in the U.S., with George Washington serving his own recipe at Mount Vernon. No single "invention spot" exists due to its murky evolution from posset and similar punches.

Key Historical Milestones

Modern Twists and Popularity

Eggnog remains a holiday staple, especially in the U.S. and Canada, often spiked with rum, brandy, or bourbon. Recent discussions, like 2025 Reddit threads, highlight homemade recipes with secret spices amid its viral winter appeal. In 2026 trends, it's seeing gourmet revivals with vegan or low-alcohol versions.
