Eggnog – Love It or Love to Hate It?
Eggnog is a traditional holiday drink made of eggs, milk, cream, spices, and one or a combination of rum, whisky, and brandy. Eggnog is loved by many but detested by others.
The term “eggnog” is a generic term that is not eligible for trademark protection by any single person or entity for EGGNOG beverages or flavored foods—of course, like APPLE for computers, EGGNOG could serve as a trademark for a wide range of non-‘nog goods or services such as shoes or tax consulting. Indeed the United States Patent and Trademark Office has determined that the term EGGNOG is considered to be a generic name for daquiris and taffy.
However, entrepreneurs in the EGGNOG space may find that intellectual property protection may be available. Copyright protection can apply to a creative literary expression of an eggnog recipe, or photographs and videos of eggnog-related content. Recipes may also be protected by treating them as “trade secrets” for commercially sold eggnog beverages. Patents may also be available for novel and non-obvious innovations in the EGGNOG ingredients or manufacturing process.
The origins of eggnog are equally entertaining:
History
Eggnog may be tracked back to the medieval British beverage posset – a warm, thickened milk drink made with wine or beer, cream or sugar, eggs, bread or oatmeal, and spices. The term “eggnog” was apparently first used circa 1770 and its name refers to either “nog” (an old English term for “ale”) or “noggin” (a small wooden mug often used for serving the beverage), depending on whom you ask.
British aristocracy drank posset with sherry as a signal of wealth. Later, Monks added eggs and figs to posset and crafted a drink that was reserved for the British elite due to egg and sherry shortages.
In the U.S., colonists found the ingredients to make eggnog were more prevalent and the drink became popular before 1800. The colonists tended to use rum, but southern families preferred bourbon or whiskey.
In the early 20th century, refrigeration became more widely available, and eggnog became more associated with the holiday season.
Fun Facts
George Washington was known for serving an eggnog-like beverage to his guests, purportedly from his own recipe created in Mount Vernon.
Eggnog was once thought to have medical use and was recommended for patients recovering from diphtheria, dysentery, malaria, surgery, ulcers, and tuberculosis.
There is a semi-official U.S. Supreme court recipe for eggnog, which was unearthed in the late Chief Justice Harlan Fiske Stone’s paperwork.
Eggnog is known in Scotland as “Auld Man’s Milk” and in the United Kingdom as an “egg flip.”
Eggnog is blamed for causing a riot at West Point on December 24, 1826, during which approximately 70 inebriated cadets assaulted offers and destroyed the barracks in which the cadets had tried to barricade themselves.
In modern times, National Eggnog Day occurs on December 24 each year.
Variations
Today, eggnog is popular throughout the English-speaking world. In the American south, eggnog is made with bourbon. Regional variations include long-aged Creole eggnog, classic hot eggnog, and a “coquito” (coconut milk-spiked eggnog that is often eggless) and those in Mexico, Belize, and most of Latin America prefer eggnog called “rompope” that uses cinnamon sticks rather than ground cinnamon. Eggnog in Bolivia and Peru, called biblia con pisco, contains no milk or cream.
Germans call eggnog “biersuppe” and is made with beer and its cousin is called “Eierpunsch” made with white wine.
In Venezuela and Trinidad, eggnog is called “Ponche crema.” Finally, Chileans enjoy Cola de Mono, often described as something between eggnog and a White Russian.
