Many people instinctively store Baileys Irish Cream liqueur in the fridge after opening, but experts say this is unnecessary. According to the manufacturer, Baileys can be kept at room temperature, provided it is stored between 0°C and 25°C (32-77°F) and away from direct sunlight.
Whether opened or sealed, a bottle of Baileys remains good for two years from the date of bottling. The best-before date printed on the back of the bottle indicates its freshness. Chilling the liqueur does not extend its shelf life, though it may be a matter of personal preference.
However, plumbing professionals from MyBuilder.com warn against disposing of leftover Baileys down the sink. The cream liqueur has a high fat content, classifying it as a FOG (Fats, Oils, and Greases). Pouring it down the drain can stick to pipes, cause blockages, and contribute to fatbergs in sewers.
For those who have an old bottle past its best-before date, the advice is to dispose of it responsibly rather than risking plumbing issues. Proper disposal methods include checking local recycling or waste guidelines for alcohol or creamy liquids.
