Can you freeze Baileys? Yes, but you’ll regret it. The alcohol keeps it from turning into a solid ice cube, so you’ll get a slushy, separated mess. It’s not dangerous to drink after thawing, but it’ll taste like a sad, watery ghost of your former self. Use it for baking instead—Baileys brownies are a divine way to dispose of regret.
Pro tip: if you’re storing an open bottle for more than two months, squeeze out the air from the bottle before capping it. Oxygen is the enemy. That’s right—treat your Baileys like a vampire avoiding sunlight and fresh air.
