So, how long? Five to seven days after opening. Toss it after a week, no guilt. Your stomach will thank you, and your holiday memories will stay sweet.
Think of it like a party guest: eggnog is wonderful for a few days, but by the end of the week, it’s time to say goodbye. Wave it off with a smile, make a fresh batch, and keep the cheer going.
Now go enjoy that last glass—just check the smell first. Cheers, you festive genius.
