Forget the date for a minute. Your nose and eyes are like those wise grandparent figures who just know when something’s off. Take a whiff—does it smell sour, yeasty, or like a forgotten gym bag? If yes, toss it immediately. Fresh eggnog smells like vanilla, cream, and a hint of holiday cheer.
Next, look at it. If you see chunks, separation that doesn’t shake back together, or any weird colors like yellow or green (yes, that can happen), don’t risk it. A little separation is normal—just give the carton a vigorous shake. But if it looks like cottage cheese swimming in milk, you’ve got a clear sign it’s time to say goodbye.

If you made your eggnog from scratch with eggs, cream, and maybe a splash of bourbon, your timeframe is much shorter.
