I guess the answer to that question would be NO, especially if we look at the early uses for eggnog.
I saw a post this morning from the grocery store in New Germany saying that they had just received their first eggnog of the season.  Not gonna lie, I will probably pick up a carton when I see it.
So where did this now holiday beverage originate?
I love the idea of the picture I saw once.  They had a chicken laying eggs in a bowl while the cow was adding milk and at the same time emptying a bottle of rum in the bowl.  That might not be a factual account though.
According to Wikipedia eggnog was used as a cold remedy in the past… “most agree eggnog originated from the early medieval” British drink called posset,^[14] which was made with hot milk^[7] that was curdled with wine or ale and flavored with spices. In the Middle Ages, posset was used as a cold and flu remedy.”

Eggnog, historically also known as a milk punch or an egg milk punch when alcoholic beverages are added

 

Now more Canadian than eggnog is Moose Milk.  In case the colder weather really bothers you this year, you could up the anti a bit with this military beverage.
