In 18th century England, eggs and fresh milk were luxury items that only the wealthy could afford regularly. British aristocrats literally hoarded these ingredients as status symbols, serving them in elaborate drinks at parties to show off their wealth.
American colonists thought this was absolutely ridiculous. They had abundant access to eggs, milk, and cheap rum from the Caribbean trade routes. So they decided to create their own version as a deliberate mockery of British pretentiousness.
They mixed eggs, milk, and massive amounts of alcohol into a thick, custard-like drink and called it "egg-n-grog"—basically "egg and booze." The whole point was to take ingredients the British elite treasured and turn them into something common, excessive, and frankly kind of gross.
The colonial version was also significantly boozier than anything the British made. We're talking drinks that were sometimes 50% alcohol or more. It wasn't meant to be refined or elegant—it was meant to be a working-class statement.
Here's where it gets weird: the drink caught on specifically because it was seen as a rebellious, anti-British beverage. During the American Revolution, drinking eggnog became almost patriotic—a liquid middle finger to British customs.
George Washington had his own recipe that included rye whiskey, rum, AND sherry—plus brandy for good measure. His version was so alcoholic that historians believe guests at Mount Vernon were probably getting absolutely hammered at holiday parties.
The drink's association with Christmas came later, mostly because winter was when families butchered livestock and had access to fresh cream and eggs. It became a seasonal treat simply because the ingredients were only reliably available in cold months.
Fast forward to today, and we've completely forgotten the satirical origins. We're now drinking a beverage that was literally invented as a joke—a colonial parody of British wealth that somehow became a cherished tradition.
The final irony? Modern store-bought eggnog contains barely any alcohol and costs more than regular milk. We've turned a working-class mockery of elite luxury into... an actual elite luxury item. The aristocrats won after all.
