I’ve seen people throw away Baileys that was “expired” by three days. Stop doing that. The “best by” date is for factory-fresh flavor, not a poison alert. If it smells fine and looks smooth, you’re good for months past that date. I once found a bottle that was eight months past its date in my parents’ cabinet. It was still delicious. (Don’t tell my doctor.)
That said, don’t push it to a year. At that point, you’re not drinking Baileys—you’re participating in a Cream Apocalypse. The texture will turn grainy, and the alcohol flavor will fade, leaving a weird sweet-sour note that makes you question your life choices.
